The photoelectric conversion efficiency of monocrystalline silicon solar cells is about 18%, solar panel and the highest is 24%. This is the highest photoelectric conversion efficiency of all types of solar cells, but the production cost is so large that it cannot be widely used. Since monocrystalline silicon is generally encapsulated with toughened glass and waterproof resin, solar panel it is durable and has a service life of up to 25 years.
The manufacturing process of polycrystalline silicon solar cells is similar to that of monocrystalline silicon solar cells, but the photoelectric conversion efficiency of polycrystalline silicon solar cells has to be reduced a lot, solar panel and its photoelectric conversion efficiency is about 16%. In terms of production cost, it is cheaper than monocrystalline silicon solar cells, the materials are simple to manufacture, the power consumption is saved, solar panel and the total production cost is lower, so it has been developed in a large amount. In addition, solar panel the service life of polycrystalline silicon solar cells is shorter than that of monocrystalline silicon solar cells. In terms of cost performance, solar panel monocrystalline silicon solar cells are slightly better.
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, solar panel the silicon material consumption is low, solar panel and the power consumption is lower. The advantage is that it can generate electricity in low light conditions. However, solar panel the main problem of amorphous silicon solar cells is that the photoelectric conversion efficiency is low. The international advanced level is about 10%, solar panel and it is not stable enough. As time goes by, its conversion efficiency decreases.
