The demand for polysilicon mainly comes from semiconductors and solar cells. According to different purity requirements, solar panel it is divided into electronic grade and solar grade. Among them, electronic grade polysilicon accounts for about 55%, solar panel and solar grade polysilicon accounts for 45%. With the rapid development of the photovoltaic industry, solar panel the demand for polysilicon from solar cells grows faster than the development of semiconductor polysilicon. The demand will exceed electronic grade polysilicon. In 1994, solar panel the total output of solar cells in the world was only 69MW, but in 2004 it was close to 1200MW, solar panel an increase of 17 times in just 10 years.
Crystalline silicon solar cells: polycrystalline silicon solar cells, monocrystalline silicon solar cells. Amorphous silicon panels: thin-film solar cells, solar panel organic solar cells. Chemical dye panels: dye-sensitized solar cells. Flexible solar cell
