Different types of solar module(1)

Monocrystalline silicon(solar module)
The photoelectric conversion efficiency of monocrystalline silicon solar cells is about 18%, and the highest is 24%, which is the highest among all kinds of solar cells, but the manufacturing cost is so high that it can not be widely used. Because monocrystalline silicon is generally encapsulated with tempered glass and waterproof resin, it is durable and has a service life of up to 25 years.

polysilicon(solar module)
The manufacturing process of polysilicon solar cells is similar to that of monocrystalline silicon solar cells, but the photoelectric conversion efficiency of polysilicon solar cells is much lower, and its photoelectric conversion efficiency is about 16%. In terms of production cost, it is cheaper than monocrystalline silicon solar cells. The materials are easy to manufacture, save power consumption, and the total production cost is low. Therefore, it has been greatly developed. In addition, the service life of polycrystalline silicon solar cells is shorter than that of monocrystalline silicon solar cells. In terms of performance price ratio, monocrystalline silicon solar cells are slightly better.

Amorphous silicon(solar module)
Amorphous silicon solar cell is a new type of thin-film solar cell appeared in 1976. It is completely different from the manufacturing methods of monocrystalline silicon and polycrystalline silicon solar cells. The process is greatly simplified, the consumption of silicon materials is small, and the power consumption is lower. Its main advantage is that it can generate electricity under weak 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. With the extension of time, its conversion efficiency decreases.
