What are the kinds of silicon solar cell
There are three in the world are commercial silicon solar cells, monocrystalline silicon solar cells, polycrystalline silicon solar cells and amorphous silicon solar cells.
For single crystal silicon solar cells, due to the use of single crystal silicon materials and the semiconductor industry, with the same quality of materials, make the use cost of single crystal silicon is expensive.
Mainly used in solar street light;
Polycrystalline silicon solar cell crystal direction without rules, meaning in the positive and negative charges of electricity cannot all be PN junction place, because the charge on the boundaries between crystals and crystal may be due to the irregular of crystal loss, so the efficiency of polycrystalline silicon solar cell generally lower than monocrystalline silicon solar cells, mainly used for solar photovoltaic power generation and solar garden light.
Amorphous silicon solar cells belong to the thin-film batteries, low cost, but the photoelectric conversion efficiency is lower, the stability and crystalline silicon solar cells, most used in weak light power supply is available at the moment, such as watches, calculators, etc.
General transition of monocrystalline silicon solar electricity and photoelectric conversion efficiency for 13 & ndash;
15% the transition of polysilicon solar electricity and photoelectric conversion efficiency of 11 & ndash;
13% the transition of amorphous silicon solar battery photoelectric conversion efficiency of 5 & ndash;
8%
