China Clean Energy: prosperity and embarrassment to the

Filed under: Battery News — Tags: , , , , , , — admin @ 11:14 pm

December 21, the capital of 16.74 billion yuan in the Sino-French joint venture - Taishan Nuclear Power Joint Venture Co., Ltd. was formally established. The company is currently the largest investment in energy companies together. This project is the rapid development of clean energy in China in miniature. rechargeable laptop battery , dell latitude d510 battery,dell latitude d520 battery,dell latitude d600 battery,dell latitude d610 battery,dell latitude d620 battery

There is such a set of data shows that China has built the world’s largest nuclear power in the country: At the end of November this year, already has 11 nuclear reactors with a total production capacity of 9 1 million kilowatts, to approve the construction of nuclear power units to 24 units with a total installed capacity of 25.4 million kilowatts. Wind power in China’s installed capacity has increased to double in three consecutive years and the first three quarters of this year to incomplete statistics showed that the total cumulative wind power capacity installed in the country reached 15.85 million kilowatts by the end of 2010 is expected to more than 30 million kilowatts by 2020 could exceed 100 million kilowatts. sony vgp-bps2 battery,sony vgp-bps2a battery, sony vgp-bps2b battery , sony vgp-bps2c battery , sony vgp-bpl2 batteryChina Industry photovoltaic and solar thermal in recent years have shown rapid development momentum, particularly in the PV capacity and output has ranked first in the world … …

German Institute for World Economics expert reasons Cihuo Fu said: “China should overtake Germany in 2009 as the total investment in renewable energy projects than any other country.” But the economic study devoted to energy experts, the world has also said: “China field of renewable energy technology has no basis.” Foreigners “frank” exposed the Chinese industry to clean energy behind prosperity of embarrassment.

Focus on a “landscape” behind the lack of self-innovation, sustainable development, concern

Turning to the achievements in the field of clean energy, China in recent years, wind, solar and others of the renewable energy industry, the rapid growth in most of the “landscape”.

Let me talk about wind energy. From the National Council of Energy data show that at the end of 2008, wind power in China’s installed capacity has increased to double for three consecutive years, reaching 12.17 million kilowatts, ranking fourth the world, the first three quarters of this year, driving 19 wind turbines in the main provinces (autonomous regions) 93 New wind power projects completed with a total installed capacity of 5.59 million kilowatts, a total installed capacity of domestic production of about 15.85 million kilowatts. Is expected by the end of 2010 should exceed 30 million kilowatts.

The Chinese wind power development fast makes the World Wide Fund for Nature in Beijing on behalf of Mr. Dermot Gorman strongly “encouraged”. He quickly said, “China at about installing one megawatt of wind, more than a week to add a thermal power plant is more encouraging.”

In addition to solar energy. According to statistics, 1 / 3 of solar cell manufacturers from China, this figure is six times more than the United States. National energy experts from the Expert Advisory Committee, Xu Hong, director of the China Institute of Electrical Engineering Chinese Academy of Sciences said the “Economic Information Daily” Reporter, the production capacity of China’s current energy solar photovoltaic and ranks first outing in the world with the “clear plan”, “send electricity to rural”, “Golden Sun Project and a number of national implementation of the project, toshiba pa3420u-1brs battery,toshiba pa3450u-1brs battery,toshiba pa3478u-1brs battery the solar heating market production of electricity have also begun to start soon.

However, wind energy in China and solar energy, “landscape” but there are worries.

In wind energy, for example, several years ago because the Separate Ways capital optimistic about the market for wind energy equipment, swarmed, not the imported machine, which is seeking licenses as a result, domestic manufacturers the majority of fans do not own the intellectual property rights. For example, experts of power within the wind, Chen Tao, said: “For example, the Shanghai Electric is licensing the company to buy the German DeWind paying the deposit, the Germans have learned with drawings of hands on how to make a series of wind energy facilities can not make any changes to innovate. There are no property rights independent, which means that technically can not be slavishly followed the German to go. ”

2009 Hui-funded $ 3.0 billion in China in the world wind energy giant Vestas Wind Industry has told the media: Vestas in the goal of China is to achieve 100% localization of production fan. However, the recent “Economic Information Daily” journalists have traveled to the city of Aarhus, Denmark, headquarters of Vestas, in an interview found that this world-class corporate wind power, the basic technology - Control systems in plants and R & D Center, sony vgp-bps8 battery,sony vgp-bps9 battery ,sony vgp-bps10 battery ,sony vgp-bps11 battery , Sony VGP-BPL11 battery , sony vgp-bps13 battery  also failed to transfer any other country than Denmark. Its control system, factory Thoroddsen chairman, said: “produced by the technology base of the plant is sufficient to meet the needs of enthusiasts Vestas in the world.”

The industry of solar energy. Xu Hong-Hua researcher said: “Our country is today the industry of solar energy in the world, one of the largest markets, but the market alone can not be redeemed prior-art technology. Insufficient capacity of independent innovation, sustainable development, lack of capacity, is the soft underbelly of the industry of solar energy in China. ”

According to Great Wall Securities introduction Zhou Tao, an analyst with energy industry news, although some national companies have become the world’s leading solar photovoltaic companies, but in the manufacture of photovoltaic cells, the finest technology based art n ‘ have not yet mastered the hands of the Chinese people. He said: “At present, the world can be put into commercial production is the single-crystal cells and solar modules and batteries second thin film production and component in the manufacture of components thin film battery in China’s lack of core technologies, apple a1245 battery , apple a1280 battery , apple a1281 battery we need the United States, Switzerland, Japan, etc. STATE OF THE PURCHASE of the production line. ”

Focus on the strength of two third generation nuclear technology from the United States, the Chinese market

Standing to address their own energy needs and economic development in low-carbon, pitch, China attaches great importance to the area of nuclear energy. In search of clean energy, the growing demand of domestic and international situation, China has even become a major force in driving the recovery of nuclear energy. Especially for third-generation AP1000 nuclear power technology to China as the world’s first “Crab-eating person” and subject of much attention around the world.

However, in the area of nuclear energy, China seems to have played the role of the assignee of the technology. As we all know, the third power generation of nuclear technology has quoted from the United States.

In 2006, the U. S. Westinghouse AP1000 overcome Areva’s EPR, winning China’s third largest single power of nuclear generation, for three, Haiyang Nuclear Power Station to provide such units, including four units, including third AP1000 technology production nuclear energy. When we are proud to say that “AP1000 is the world by the U.S. Nuclear Regulatory Commission certified and approved by the three generations of semiconductor nuclear technology”, when in fact the need to clearly understand that China has the power of third generation nuclear (AP1000) is in fact the U.S. Westinghouse Electric the first time in the transformation of the global market.

In fact, China’s large-scale development of nuclear energy has always existed behind the baseline technology for the introduction of foreign conflicts.

Nuclear energy was a senior expert of Luqing Zhang of China has introduced three generations of nuclear plants that have different opinions. He said in an interview for both the United States, AP1000, dell inspiron 1525 battery,dell inspiron 1526 battery,dell inspiron 1720 battery EPR or French in the world have not yet completed and commercial operation of precedent, and many industry experts when Submissions were invited on the proposal could be the first to introduce a single unit, and so he began and completed the production of energy, depending on the purpose of monitoring before deciding how to develop, rather than once that they are now introducing four production units with an investment of nearly 100 billion too risky.

Introduction by China to Westinghouse AP1000 nuclear technology, Beijing University, Professor Feng Lu wrote that China should not give up independent R & D in the second reactor Qinshan mature generation of nuclear technology to improve .

“But already a fait accompli, to arguments that are no longer needed. What we need now is to build as soon as possible of these units.” Zhang Luqing said the “Economic Information Daily” journalist in 2010, is a crucial time for the node. Westinghouse has developed the ability to plan and through the testing of prototype main pumps, AP1000 will be China’s initial nuclear power in determining the status of the first construction of key projects.

It is understood that the development of nuclear power plants at the beginning, the third generation of China’s nuclear energy since the beginning proposed to introduce a “three steps” strategy: the first stage of the main square, our full participation The completion of three, and four sets Haiyang AP1000 units, the second step, focus on ourselves and external support, training of coastal and inland site of the AP1000 standard execution, build inland and coastal group of factory third nuclear power production, the completion of digestion and absorption of the AP1000 technology, third step,  hp f2024b battery,hp f4486b battery,hp f4809a battery,hp f4812a battery the formation of standard design CAP1400 and CAP1400 built science major and special technology demonstration projects to complete full independent innovation, to form China with the intellectual property rights independent of the advanced technology of nuclear energy and brands.

But three generations of nuclear power itself, “U.S. technology, the Chinese market,” the reality, but it has always been nuclear power in China were the sentences of heart.

Focus on three War low carbon: China needs to seize the heights of clean energy technologies

With the wind sweeping through the world of low-carbon industry of clean energy is the world all around development opened in spring. However, when the United Nations Climate Change Conference in Copenhagen on sites with a different economies and reduce carbon emissions around the struggle between the battlefield, we were surprised that concept of low carbon and clean energy technologies in developed countries will also slowed progress in developing a new instrument.

Carbon tariffs in many developed countries and countries endemic. June 22 this year, was the House of Representatives passed “The United States Clean Energy Security Act provisions, including China, the United States the right of non-quota countries in the application of rates carbon emissions carbon tax on imported goods.  compaq evo n600 battery,compaq evo n600c battery,compaq evo n610c battery,compaq evo n620c battery,compaq presario 2100 battery,compaq presario 2500 battery The Act came into force from 2020. The EU tariffs on the one hand, in pursuit of its carbon-win public support, first began to redouble efforts to promote the technical aspects of the carbon tax to to prepare. While France has indicated that rates of carbon will be January 1, 2010 date of introduction.

Carbon tax to promote a big noise about the same time, developed countries also use its advantage of clean energy technologies to developing countries to suppress. As the first country in the developing world, the industry of clean energy in China, although the achievements of world interest, but the lack of core technologies Querang we have to pay higher prices.

U. S. President George Obama said: “In the development of new sources of energy in leading countries, will lead the global economy of the 21st century.” Chinese-American Energy Secretary Steven Chu during the visit of a new China’s energy and renewable energy development to give highly appreciated. However, we note that many Sino-US cooperation in the field of new energy-related projects, most exports of U.S. technology to the Chinese market. For example, Westinghouse third AES Power Company nuclear generating methane projects in coal mines do not have the wind and so on.

“You do not have the basic technology, we will be controlled by others.” XU Chinese researcher said that “the path of global development clean energy, China should establish an independent system of intellectual property rights, sustainable development, industrial system.”

NDRC Energy Research Institute researcher Feng Zhou to accept the “Economic Information Daily”, an interview, said that China should not be content with a variety of clean energy available to the huge capacity, acer aspire 5520 battery but rather the management of intellectual property rights independently. He said: “In the past, we have a lot of money for capacity expansion of clean energy, the next step should be around the core technology in R & D and research.

U.S. Scientists announce new nuclear batteries no need to be recharged

Filed under: Battery News — Tags: , , , , — admin @ 9:35 pm

Scientists at the University of Missouri, announced they are developing a new type of battery, its battery life standard of more than 1 million times.

What is the Mars Science and technology have made this life such a long battery life? The original, this battery is that some radioactive elements decay of isotopes in the energy generated. Simply means that a nuclear power.

The main advantage of this battery will not charge for providing electricity for some very long half-life isotopes, while the half-life, they will listen to the release of energy. For example, the fifth cycle, the First Family VIIB element technetium isotope Tc-97, its half-life of more than 260 million years. Imagine the future as long as a coin-size batteries, your cell phone you can still use your grandchildren, great-grandfather who was a generation without charge, how it looks.

According to the developer who introduced the use of energy decay of the battery is already used for military and aerospace, but the size and weight are great, but they expanded the size of the new product is only slightly larger than the one-franc piece, and about the thickness of a human hair. In addition, they still use the battery in the semiconductor material liquid to overcome the traditional solid-chip inside the battery charged particle radiation easily corrupted.

This battery is currently the main target application areas of micro-nano-electro-mechanical energy. Developers have also said that although the use of radioactive elements, but the technology is safe. He stressed that, in fact, the use of nuclear energy has long been a variety of cells, such as pacemakers, satellites and space equipment submarine system and so on

Currently, the group has filed a provisional patent on the battery.

The sharing of resources to build solar cells Sharp Joint Factory

Filed under: Battery News — Tags: , , , — admin @ 9:30 pm

Sharp has announced it will build in Osaka Prefecture Sakai City line LCD panel manufacturing plant and a new solar cell. To reduce the 42-inch, 57 inch, 65 inch widescreen LCD panel and the cost of thin film solar cells, Sharp is building new facilities such as LCD and solar cell, “a factory town.” Combine a total area of 1.27 million m2 (for the Kameyama plant four times), with a total investment of 1 billion yen.

10th generation LCD plant: With vertical integration upstream and downstream to reduce costs

LCD panel plant will be the first in the use of industry size substrate is 2850mm x 3050mm 10th-generation glass substrates, try to put into operation in March 2010. The objective is to conduct a thorough integration upstream and downstream vertical, and further reduce costs. Until now, the glass substrate supplier Corning (Corning), color filter supplier Dai Nippon Printing and electricity suppliers Kansai Electric Power said it would join a joint facility.

The manufacture of glass substrate from silicon raw materials made from start to produce the glass substrate moving through the factory and sent to the production line TFT and color filter production line. dell latitude d620 battery Glass substrate not only buying a business will also receive the vicinity of a joint facility of the glass supply companies to maintain a purchasing mechanism for both companies. Color filters also use the same mechanism.

In addition, Sharp also plans to import new technologies such as inkjet printing, as compared to vertical integration to reduce costs resulted in a greater effect.

Thin-film solar cell factory: LCD plant with a shared infrastructure to reduce costs

Facilities cells in thin layers for solar energy, the annual production capacity to reach 1000MW plant will be a giant LCD plant construction during the same period. This is a sharp focus on the multiplier effect of energy saving “(LCD) and” can not create “(solar cells) for the business backbone of one of measures. Largest Solar Sharp plans to share infrastructure with LCD panel plant, reducing costs while making the world production of plant cells. hp f4486b battery The objective is to 1000MW by increasing the size of production to keep the world No. 1 market share. The current annual global production of solar cells just over 2000MW, the new facility is completed, production will increase from Sharp to half of current world production.

Regarding the sharing of infrastructure with the LCD, Sharp said that the use of amorphous silicon can be manufactured using SiH4 gas, water and substrate handling equipment. Sharp believes that we can reduce costs by sharing infrastructure costs to acquire the world’s leading competition. Sharp has demonstrated through their own efforts to reduce costs to compete in the global market ideas.

In addition, including thin film solar battery  production and use of the size of the substrate, etc., the specific plan is still under discussion between the thin film solar cell production facility details will be announced later in the program is entered.

In 2010, the market share of widescreen LCD continues to grow

2850mm x 3050mm 10th-generation glass substrates can be cut in six separate 65-inch panels, eight panels of 57 inches, 15 by 42 inch panels. On the LCD market, investment in new facilities in the background, Sharp, Mikio Katayama, president of this prediction: “At present, 32 inches is the biggest selling model, on this basis, the 2010 42 -inch market as a whole will account for 40% over the 50-inch widescreen is also increased. (in display technology) Liquid Crystal in the future continue to improve product performance and market expansion. In this case, we will actively carry out the LCD screens for export. Previously, due to meet the demand, motorized, it can only lead to export small scale, with the creation of the new plant, we will actively carry out the export. “

Filed under: Battery News — Tags: , , , , — admin @ 4:01 am

Cell phones are commonly used in everyday items, batteries, security is important Municipal Technical Supervision Bureau experts on how to select high quality phone batteries for the mobile consumer to the guide. According to experts, the piles of bad phone quality and potentially dangerous. Using the mobile phone original battery, is to ensure the safety of the more important. In addition, the high temperature heat can cause the upgrade of the battery when explosives are to recharge the batteries, or upgrade your phone, be sure to choose a place away from heat, while avoiding the direct rays of summer sun. Some changes in the mobile, but it may lead to the explosion of derogatory phone. Mobile is a manufacturer of sophisticated communications equipment in the design of its security will be strict validation, performance is better, but this will be amended to change, may lead to mobile phones has exploded. In addition, do not talk too long, responsible not try to call, do not phone hung on the chest as much as possible on the mobile phone bag, multi-headset to answer the call.
According to experts, to identify counterfeit batteries sony vgp-bps2a battery  should pay attention to the following aspects: First, the duration of standby time. The battery life saver is an important indicator to measure the strengths and weaknesses of the battery. Waiting time and high quality manual on the logo to be basically the same. The false identification of only half the time. Some low-quality battery is used as the core of secondary battery cells, made by compiling new packages. Secondly, the battery capacity. Mobile phone battery capacity in general of 1000 mA / hour, or two kinds of 1000mAh. Some of the smaller capacity battery has not been identified, the label is unreadable. By measuring the current of the battery, you can identify the authenticity of the apple a1060 battery. Thirdly, security. Mobile phone battery when there is no internal circuit protection, it is easy to distortion, leakage, or even an explosion. Many piles of bad quality for a low price to attract consumers, removed the piece of shield circuit to earn more profits.

China’s battery sharp decline in export volume during the first half blocked

Filed under: Battery News — Tags: , , , — admin @ 2:50 am

(Time :2009-10-14 10:06:09)
According to the National Bureau of Statistics show that in 2009, June 1 in China battery industry accumulated value of industrial output of 136.34 billion yuan, up 7.9%, cumulative sales value of industrial production 130.45 billion yuan, up 0.9%; completion of delivery of the export value of 43.41 billion yuan, down 11.3%.

Among them, lead battery acid production increased by 16.7%, alkaline battery production fell by 32.0%, production of primary cells decreased by 13.2%.

In addition, May 1st solar pointing 022 million export volume, the cumulative value of exports 1.518 billion U.S. dollars, an increase of 20%. Ni-Cd battery exports cumulatively 87.5373 million, down 60.8%.

Button alkaline manganese batteries, cylindrical type alkaline manganese batteries, lithium batteries, lithium-ion battery, home-style export-lead battery acid decreased. Other types of alkaline manganese batteries, alkaline manganese batteries are 6LF22 essentially flat, as exports dropped significantly.

Fixed type, type of storage and lead acid traction battery used lead acid batteries and other industrial exports fell by half.

Industry Analysis, nickel-cadmium batteries are mainly used in power tools, as directed by the battery from the EU included in the regulated products. Nickel-cadmium batteries because of States have adopted a policy on environmental protection, limiting their use and market size, China has also promulgated a policy on the environment in the Ni-Cd battery included in the directory couples high, and removed tax rebates on exports, to ban the processing trade. Because incidents of environmental pollution by cadmium frequently, some companies have ceased operations Ni-Cd battery manufacturing. As the financial crisis, power tools, production and sales declined, lithium-ion battery competitive market pressures lead to multi-market for nickel cadmium batteries are declining, exports have declined significantly.

In addition, the common zinc-manganese batteries, nickel-hydrogen battery exports cumulatively 258 million, down 29.8%, while its exports decline by 10 percentage points higher than the volume of exports, experts suggest that companies should improve the battery unit.

Fake battery explodes, Manufacturers nowhere to find

Filed under: Battery News — Tags: , , — admin @ 2:35 am

Recently, Mr. Chiang Chao-An Giang to spend a certain mobile phone accessories stall 13 yuan to buy a mobile phone battery. More than 10 hours to charge the phone before going to sleep, as usual, the results an hour later, there was an explosion fried awake. The result: his right eye to collapse and fries charger, battery explosions, while the left eye was bleeding, did not see the light.

It is only 70 yuan, about 6 km bike has traveled to two hospitals “hello”. Finally, while accepting a rescue operation, but doctors have said frankly: the left eye and the eye-eye in the split-East The content of logistics show, seriously injured, the basis of blindness is undoubtedly . Can do is to vigorously defend the right eye will not be involved in infection. “You said it’s a good thing to remind you not to buy a cell phone batteries, counterfeit!” Said Mr. Jiang.

The seller can not find the manufacturer says

“This battery is not an original battery, I can not find this explosive battery manufacturers, and because it is in advance of the shipment.” Yesterday afternoon, the country head stall Communications supermarket, Ms. Chen was indeed confirmed the blast cells their stalls for the sale. After learning that the battery exploded wounding, they are early in the morning with a basket on the injured taken to hospital for give comfort and hope to resolve in private consultation with the wounded. “We’re really sorry, and certainly not escape responsibility.” Said Ms Chan.

However, Chiang Chao-An, and are not suitable to a private address. At 3 am, Chiang Chao-An in bed, called 110, the ongoing police investigation.

When journalists Motorola (China), the Department of Public Relations Phone Manager when Ms Luo Ping, she said that the phone batteries original mobile phone is secure enough. The company produces batteries manufactured using high quality batteries, the battery in high temperature, high humidity and other difficult problem of environmental quality does not occur at any time, even in the current unstable situation voltage, and still be able to protect the circuit works properly. In addition, “consumers by supporting the use of the best original charger. Due process of charging battery charger Parents can monitor, adjustments and stops charging automatically, poor quality chargers on the market have such a function. ”

Expert Tip: In the City National Electronic and number of adjacent street, manufacture and sell a cottage sellers battery minorities, journalists rough estimate, the country each month, several million to 10 million cottage with a little cell access channels distribution has become a cell phone use One of the biggest risk factor. Standards In China today “phone use lithium-ion battery cells general, the mobile phone battery must pass through a series of cons-explosive testing, compliance to the factory after the sale, and this is clearly a live production of batteries for mobile phones do not meet national standards, hoping consumers cautious use.

Nissan reduction Trilogy: energy conversion, energy storage and efficiency gains

Filed under: Battery News — Tags: , , , — admin @ 10:10 pm

Future of the automobile may not be cars, but now do not know “he” will be called something, so we in the “he” Features - the movement called “it” for mobile tools. Nissan Motor Co. plans for the future is one of mobile devices, electric vehicles.

Nissan to develop electric vehicles have their origin, carbon dioxide Business (CO2) concentration is below the long-term goal 550 ~ 450 ppm, which, in 2050, all new cars which emit CO2 compared to 2000, must be reduced by 70% ~ 90%. Nissan To achieve long-term objective of long-term reduction of CO2 in the strategy is divided into short term and long term and short-term method is to improve ICE efficiency, long term is to expand the electric vehicle market and in optimizing the use of renewable energies. Nissan said to reduce carbon dioxide to be fully realized, we must start from three aspects, namely: energy conversion, energy storage and efficiency gains.

The battery is the heart of the development of electric cars

Nissan electric cars that were optimistic about the prospects for the main reason is that the battery technology over the past 15 years has come a long way down the aisle, in the 1900s invented the lead acid batteries, has a capacity of less than 0.5kW/kg 1992 invented the nickel-hydrogen cells, build capacity in 2003 reached 1.5kW/kg; lithium 1997 years Cylindertype and lithium batteries in 2003 Laminatedtype strengthen the capacity attained 3kW / kg. In addition, the size of the battery greatly reduces the size of lithium batteries is the same construction and capacity of lead acid battery 1 / 8, not only that, since the invention of the stack since the size of the battery has been halved.

Development of the electric car from Nissan is also based on lithium batteries as the heart, is expected by 2010, an official of the United States and Japan market, 2012 will enter the global market, which uses lithium batteries laminated electric vehicles, high speed response to the engine, the maximum speed of over 100 miles, in collaboration with the driver’s account, the highest multiplier of 5 people. Nissan to develop electric cars that the basic technology of the company for high capacity and stability of the battery technology, motor and battery performance can be adjusted higher, and optimize the performance of other important components. Electric cars of the main components include: battery, BBWDCDC & JB, Charger, PTCHeater, Motor, AC-Compress, INV, ABS and airbag.

Provisions for taxation Feis Liang

According to Nissan USA, Great Britain, Germany, France and Japan, studies have shown that most of the day round trip distance of 50 kilometers, so the coverage area as well as station load can be arranged, two types of electric vehicles can navigate without hindrance, the two common types of loading stations are charging stations and fast-charge stations. General Charging Station costs ¥ 45,000 ~ 150,000 yen in order to charge voltage 200V, assume 8 hours for family and automobile traffic at the plant; rapid charging stations costing as much as 5 million yen, 10 minutes load can be carried 50 km, suitable for the construction of shopping malls and public places. According to Nissan, the survey said that the Japanese have spent an average of 8 minutes in convenience stores, supermarkets, 52-minute stay, restaurants, 54 minutes, Coin-Operated gate terminal 120 minutes, because the time Japanese residence minimum of 8 minutes, if the charging station is designed for 10 minutes to allow electric cars to run 50 km. In the future information system on vehicles, but also must be able to provide real-time continuous driving charge there, charging distance of the station and the number of electric charge and other information.

2009 We are concerned that solar cells

Filed under: Battery News — Tags: , , , , — admin @ 10:03 pm

In the solar system of energy production, the most complex technology can be considered as part of solar cells. The solar cells are at the heart of the solar system, its development and production will have a direct impact on the popularity of solar energy and development.
      The principle of solar cell is able to live a sunlight in the pn junction semiconductors, the formation of new hole - electron pairs in the pn junction under the action of the electric field, P the flow hole from area sector n, the electronic flow of N from the p-zone, then after the formation of the current passing circuit. The solar energy solar energy means that there are two ways, one is light - heat - way conversion of electricity, and the other is light - electric direct conversion approach.

        

In Tokyo, Japan in 2008, sun exposure, a Japan Institute of Industrial Science and technology workers show flowers and leaves are shaped models of solar cells.

Recalling the development of solar cells in the world

      Since 1839, the French scientist Becquerel (Becqurel) found that illumination of semiconductor materials can arise between different parts of the potential difference. This phenomenon is known as the “photovoltaic effect, called the photovoltaic effect. In 1954, U.S. scientists Qiabin Pierson and Bell Labs in the U.S. for the first time made a practical silicon solar cells, gave birth to the solar energy is converted into electrical energy technology of photovoltaic energy production practice .

      Since then, increasing the types of solar cells, a growing range of applications, the size of the enlarged market. For 1994, sales in the world reached 64 megawatts of solar cells, showing a trend of rapid growth. In this century, some developed countries have launched a development, including solar cells, including renewable energy projects. Research on solar cells and production in Europe, the Americas, Asia, large-scale deployment. The United States and Japan to compete in the PV market dominance of the world, competing for the introduction of solar energy research and technology development programs. In recent years, world production capacity of solar cells of almost 40% average annual growth in 2003, total world production will reach 744 megawatts.

      Types of solar cells

      According to the different materials used in solar cells can be divided into: 1, the silicon solar cell 2 to inorganic salts such as gallium arsenide III-V compounds, cadmium sulphide, selenium, indium of copper compounds such as multi-material cells, 3, has a high molecular materials can be prepared by the cells of sun, 4, nano-crystalline solar cells.

      Silicon is the ideal material for solar cells is silicon-based solar cells with the main reason. Above Solar cells monocrystalline silicon conversion efficiency of cells of the highest technology and most sophisticated performance of photoelectric conversion up to 23.3%. In the process of production, the overall texture of the surface passivated emitter, the doping area of technology. However, as the price of raw silicon, the complicated process and the corresponding impact of high prices of silicon costs, thus reducing considerably the cost is very difficult, can be achieved massive popularity of solar energy.

      With the continuous development of new materials and technologies, in other village-cell materials based solar have shown more and more attractive. International news low cost of research on mass production technologies based on polysilicon, large area silicon thin film amorphous CdTe cells, production of IEC Battery Technology Ⅲ semiconductor compounds V and effective solar cells and amorphous silicon hybrid crystalline silicon thin film photovoltaic cells and so on.

      If silicon is characterized by high efficiency, high cost of other materials, the problem of the battery is probably low cost, low-transforming. Compared to monocrystalline silicon solar cells, in addition to polycrystalline silicon, cadmium telluride loaded with other materials, electro-optical conversion efficiency of the battery does not generally exceed 15%.

      The development of solar cells in China

      In China, in 1958, began studying solar cells, first used in 1971, China launched the spacecraft. The solar cells in 1973, began to be used in the field. Because prices and limiting production, market development is very slow, except in the case of satellite power, solar cells on the ground for systems that supply power to small, as lights, railway signaling systems.

      In 2002, the departments concerned and have begun the “western provinces and autonomous regions without electricity, rural electric Scheme, through photovoltaic and small wind energy to solve the seven provinces and autonomous regions in electricity rural West without electricity problems. The beginning of this project has greatly stimulated the industry of solar energy, China has built several solar cell line of packaging, so that the annual capacity of production of solar cells increases rapidly.

      At present solar cells are already widely used in communications, transportation, consumer products and other areas, production of photovoltaics to include a research plan not only the country, and included in the national power construction, but also in a number of major projects has been applied. At the end of 2003 the installed capacity of China’s solar cells to 5 thousands. Currently, the production of photovoltaic energy has been around in the western provinces of China and the autonomous regions, and parts of central provinces and East, municipalities and autonomous regions, and put the total size of over 30 billion yuan.

      Efficient and low unit cost of solar cells has always been one of the international development goals. Similarly, production of China, promoting this fundamental problem has assembled here. Grasslands, islands, desert areas without electricity needs are enormous, but the affordability, lack of production scale and product specific problems such as weak is very visible. In the city the power system, the high cost of investment of time may be more product promotion more difficult. Therefore, improve efficiency, reduce costs, expand the scale of today must be the development and production of solar cells subject.

      In 2008, swept the global financial crisis also spread to the solar cell industry in China, declines in the fight polysilicon prices to historically low levels, the “original blue sky” of the industry solar cells, all of a sudden, “opaque”, the crisis had led many companies to cut production to cope with layoffs, etc., but I think the use of solar energy is photovoltaic irreversible trend. China has become the second largest market after the U.S. consumer, demand for electricity, the growth rate was highest in the world. The tension of the petroleum energy, resources of coal in emergency makes production methods existing electricity can not meet consumer demand, promoting solar energy demand in China is still a pressing need, the market potential is enormous. To market, to accelerate development, the solar cell industry is certainly promising.
