Third-CPV method for generating solar electricity is becoming the center of the field. The photovoltaic power generation has experienced the first generation of crystalline silicon cells and second-generation thin-film battery, the process of industrialization will gradually present systems to highly efficient power generation CPV. Compared to the previous two generations of cell multi-junction III-V CPV composed of cells, inspiron 2600 battery , with an absorption spectral important advantages of high conversion efficiency and small size required for the battery to a relatively cheap alternative to cooling device expensive semiconductor materials in the production of electricity on a large scale can be effectively applied to reduce costs, reduce energy consumption.
CPV systems have advantages and performance at high temperature conversion rates. Theoretical conversion efficiency of silicon cells about 23%, single-junction GaAs cells theoretical conversion efficiency up to 27%, multi-junction III-V on the batteries of the family of spectra ‘absorption of a more comprehensive, its conversion rate can theoretically exceed 50%. Even taking into account the condenser and the tracking error resulting from the loss, the current CPV system conversion efficiency up to 25% higher than the cell current commercially available crystalline silicon to about 17% of conversion efficiency. In addition, GaAs attenuation performance of the Department of battery temperature is higher than silicon cells, more appropriate for the high desert sun.
Production process of CPV systems more energy efficient, environmentally friendly. 417066-001 , Collapse several large smaller area of photovoltaic cells required up to several hundreds of times HCPV systems, these cell size can be converted size field of energy conversion devices.
Amount of savings in semiconductor materials, while reducing the production cost of solar energy systems and energy, making energy CPV is a recovery period shorter.
Become cost competitive CPV power and greater potential for cost reduction. With CPV technology is more mature, and the expansion of production scale can be achieved during the year 2010 has great potential to reduce the levelized cost of electricity (PMOD) lower than the crystalline silicon cell and thin film. In the future, if the production equipment for solar energy production of a carbon tax is levied, PCV recovery period will be extended to only 1 ~ 2 months, the crystalline silicon and thin film batteries s’ extend more than 1 year, when the relative cost advantages of the CPV will be more pronounced.
CPV will be a long term and the crystalline silicon cells, thin films co-exist. CPV because of the complexity of the system more applicable to large-scale photovoltaic power plants can be used to obtain a unified method of control and cooling systems. The crystalline silicon and thin-film batteries better suited to small systems of domestic and commercial energy in the long run, CPV will not completely replace the crystalline silicon and thin film market of the battery, pa3480u-1brs , as the thin film batteries can not replace completely the same crystalline silicon cells.
Size of the market with high growth potential. CPV less than 200MW currently installed worldwide, is expected in the coming years, with the technological advantages and benefits of implementation costs, market size will grow explosively in the next 10 years the average growth rate year is expected to more than 40%. In 2020, the sector’s output value up to 500 billion yuan. Currently, only a small demonstration plant to power in China in the future, as the capacity of PV and CPV will also gradually open the market.
CSP will also gradually in large scale applications. CSP system is mainly generated by the solar concentrator for the use of heat, CSP although without the use of photovoltaic cells, but still needs a lot of condenser optics. Install new capacity in 2015 should reach 5.5GW.
The applicable domestic, listed companies. Currently, there are no hardware manufacturers mature CPV, a strong dependence on imports.
Apart from the listed companies, MACRO, three-year opto-electronics, and Kazakhstan all have manufacturing operations CPV-tech, new Huaguang, crystal optoelectronics, thinkpad r40 battery , photovoltaics is Lida condenser capacity optical the future is expected CPV and CSP markets of high-speed expansion of the service.
