Amorphous silicon solar cells are new thin film solar cells that appeared in 1976. They are completely different from single crystal silicon and polycrystalline silicon solar cells. The process is greatly simplified, silicon materials are consumed less, and power consumption is lower. The advantage is that it can generate electricity in low light conditions. However, the main problem of amorphous silicon solar cells is that the photoelectric conversion efficiency is low. At present, the international advanced level is about 10%, and it is not stable enough. As time goes by, the conversion efficiency is attenuated.
