The development history of solar panels is more than the domestic solar energy

Solar panels on the development process of the first generation of solar cells, including monocrystalline silicon solar cell and polycrystalline silicon solar energy, crystal silicon solar battery invented until now, despite all kinds of silicone material problem, but is still a solar battery materials, its about

the development of the solar panels first generation solar cells including monocrystalline silicon solar cells and polycrystalline silicon solar cells. Since the invention of crystalline silicon solar cells, despite the silicon materials in a variety of problems, but they are still current solar battery materials, more than 90% of the total solar cell production. Since the 1920 s, Beijing solar energy research institute of China has been making efficient battery research. Using the surface of the inverted pyramid structure, emitter passivation, back field, such as technology, the efficiency of monocrystalline silicon solar cells at 19. 8%. The second generation of solar cell: the second generation of solar cells based on thin solar cell. Thin-film technology needs to be much less than the crystalline silicon solar battery materials, and easy to realize large-scale production. Solar cells including amorphous silicon thin-film batteries, polycrystalline silicon thin-film batteries, cadmium telluride, and copper indium selenium thin-film batteries. Nankai university of China in the late 1980 s began to study copper indium selenium thin-film batteries. Currently, it is a leading domestic and international research. Preparation of copper indium selenium thin-film battery conversion efficiency reached 12%. Copper indium selenium thin-film solar cell manufacture production line has been completed. Dye sensitized industrialization research of nanometer thin film solar cells is at a level close to the world of scientific research. It has a certain influence in this area. The third generation solar cells: the third generation solar cells must meet the following conditions: film high conversion rate, abundant raw materials, non-toxic environmental protection. At present, the concept of the third generation solar cells and simplicity is still in experimental study. Has developed the third generation solar cells include laminated band gap solar cells of solar cells, and so on. Although solar battery raw materials into the third stage, but their technical level and the manufacturing cost but not compared with the conventional silicon solar cells. After decades of efforts, finally reducing the costs of silicon solar cells, but compared with the conventional energy, it is still relatively expensive, which limit its further application.
