Japan, Sharp Corporation, announced October 22 that the application layer of the formation of an innovative technology company with long-term commitment to R & D compounds 3 junction solar cell has achieved a 35.8% of the high photoelectric conversion efficiency.
Press release 22 Sharp that the compound is different from the current traditional silicon solar cells, laptop battery rechargeable   solar panels for equipment. There are only two kinds of indium and other elements of the compound as the material to form a layer of light absorption, the photoelectric conversion efficiency than silicon solar cells, is mainly used in satellites.
Sharp is committed to research and development since 2000 by a three-layer absorption of optical layer stack of three compounds formed junction solar cells.  dell latitude x300 battery,dell xps m140 battery Composed of cells The last three junction solar materials underlying germanium are used, although the use of this material has a large current, but can not be the most common use of energy. Another type of gallium arsenide and indium materials, can significantly increase the effectiveness of current usage, but very regular atomic arrangement of production of indium arsenide high quality gallium is very difficult. Staff Sharp R & D application layer of the formation of a single technology to solve high-quality GaAs layer formation phenomenon of indium, and compounds 3 junction photoelectric conversion efficiency of solar cells of the previous 31.5% to 35.8%.
