Solar street lights are one of the more common street lights we use now. We can find that the service life of some solar cells in it is very different from that of our traditional charging street lamps. The service life of this kind of solar battery is generally between 20 years and 30 years. So for us, the street lamp must maintain a stability during the use process to minimize its loss. Therefore, the solar street lamp is a very important and wise choice for us, and its battery materials are also very good. important.
Amorphous silicon solar cell is a new type of thin film solar cell that appeared in 1976. It is completely different from monocrystalline silicon and polycrystalline silicon solar cells. The process is greatly simplified, the silicon material consumption is low, and the 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. The international advanced level is about 10%, and it is not stable enough. As time goes by, its conversion efficiency decays. Multi-element compound solar cells refer to solar cells that are not made of a single element semiconductor material. There are many types of research in various countries, and most of them have not been industrialized. The main ones are as follows: a) cadmium sulfide solar cells b) gallium arsenide solar cells c) copper indium selenium solar cells (new multi-element band gap gradient Cu(In, Ga) Se2 thin-film solar cell)
