(1) polycrystalline silicon solar cell polycrystalline silicon solar cell production process and monocrystalline silicon solar cell almost, but the polysilicon solar cell photoelectric conversion efficiency will have to reduce a lot of its photoelectric conversion efficiency of about 12%. From the cost of production, than the monocrystalline silicon solar cells to be cheaper, easy to manufacture materials, saving power consumption, the total cost of production is low, so get a lot of development. In addition, polysilicon Sichuan solar cell life than monocrystalline silicon solar cells shorter. From the performance and price ratio, monocrystalline silicon solar cells also slightly better.
(2) amorphous silicon solar panel amorphous silicon Sichuan solar cell is a new thin film solar cell in 1976, it is with the monocrystalline silicon and polycrystalline silicon solar cell production method is completely different, the process greatly simplified, silicon material consumption is very Less power consumption lower, its main advantage is in low light conditions can also generate electricity. However, the main problem of amorphous silicon solar cells is the low efficiency of photoelectric conversion, the international advanced level of about 10%, and not stable enough, with the extension of time, the conversion efficiency of attenuation.
