Japan’s Sharp Corporation 22, announced that the application layer of the formation of an innovative technology, the company’s long-term commitment to R & D compounds 3 junction solar cell achieved a 35.8% of the high photoelectric conversion efficiency.
       Sharp’s 22 press release that the compound is different from the current mainstream solar cell silicon solar cells for the material. It more than two kinds of indium and other elements of the compound as the material to form a light absorption layer, Inspiron E1405 battery , Latitude D520 battery the photoelectric conversion efficiency than silicon solar cells, laptop battery is mainly used in satellites.

       Sharp is committed to research and development since 2000 by a three-layer optical absorption layer stack compounds made of three junction solar cell. The past three junction solar cell compounds, the underlying germanium materials are used, although the use of this material will have a great current, but can not be the most current energy use. Another kind of material indium gallium arsenide, can substantially increase the efficiency of current use, but very regular atomic arrangement of production of high-quality indium gallium arsenide is very difficult. Sharp R & D personnel application layer of the formation of unique technology to solve high-quality GaAs layer of the formation of indium problem, so that compounds 3 junction photoelectric conversion efficiency of solar cells from the previous 31.5% to 35.8%.
