Classification Of Solar Panels

Crystalline silicon panels: polycrystalline silicon solar cells, monocrystalline silicon solar cells.
Solar panel
Amorphous silicon panels: thin film solar cells, organic solar cells.
Chemical dye panels: dye-sensitized solar cells.
Flexible solar cell
Single crystalline silicon solar cell
The photoelectric conversion efficiency of monocrystalline silicon solar cells is about 15%, and the highest is 24%, which is the highest photoelectric conversion efficiency of all kinds of solar cells, but the production cost is very large, so that it can not be widely used. Because monocrystalline silicon is generally packaged with tempered glass and waterproof resin, it is robust and durable, and its service life is generally up to 15 years, up to 25 years.
Polycrystalline silicon solar cells
The production 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 is reduced a lot, and its photoelectric conversion efficiency is about 12% (July 1, 2004, Japan Sharp listed efficiency of 14.8% of the world's highest efficiency polycrystalline silicon solar cells). In terms of production cost, it is cheaper than monocrystalline silicon solar cells, the material is simple to manufacture, saves power consumption, and the total production cost is low, so it has been developed in large numbers. 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 cells
Amorphous silicon solar cell is a new type of thin-film solar cell appeared in 1976, it is completely different from the production method of monocrystal silicon and polysilicon solar cells, the process is greatly simplified, silicon material consumption is little, lower power consumption, its main advantage is that it can also 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, and its conversion efficiency decreases with the extension of time.
