Monocrystalline silicon
The photoelectric conversion efficiency of monocrystalline silicon solar panels is about 15%, with the highest reaching 24%, which is the highest among all kinds of solar panels. However, the production cost is very high, so that it is not widely and universally used. Because the monocrystalline silicon is generally encapsulated by toughened glass and waterproof resin, it is rugged and durable, with a service life of up to 15 years and up to 25 years.
Polysilicon
The production process of polysilicon solar panels is similar to that of monocrystalline silicon solar panels, but the photoelectric conversion efficiency of polysilicon solar panels is reduced a lot, and its photoelectric conversion efficiency is about 12% (the world's highest efficiency polysilicon solar panels with 14.8% efficiency listed by Sharp in Japan on July 1, 2004). In terms of production cost, it is cheaper than the monocrystalline silicon solar panel, the material is simple to manufacture, saving power consumption, and the total production cost is low, so it has been developed in a large number. In addition, the lifetime of polysilicon solar panels is shorter than that of monocrystalline ones. In terms of performance and cost, monocrystalline silicon solar panels are slightly better.
Amorphous silicon
Amorphous silicon solar panel is a new type of thin-film solar panel appeared in 1976. It is completely different from the production method of monocrystalline silicon and polycrystalline silicon solar panel. The technological process is greatly simplified, and the silicon material consumption is less and the power consumption is lower. However, the main problem of amorphous silicon solar panels 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.
Multiple component compound
Polycompound solar panels are solar panels that are not made of a single element semiconductor material. There are many varieties studied in various countries, most of which have not yet been industrialized, including the following:
