The Main Material Structure Of Solar Panels

- Aug 29, 2017 -

Conventional solar cells are generally two layers of glass in the middle of the EVA material and the structure of the battery, such components heavier weight, the installation of the need for stent, easy to move.

At present, crystalline silicon materials (including polysilicon and monocrystalline silicon) is the most important photovoltaic material, its market share of more than 90%, and in the future for a long period of time is still the mainstream of solar cells. Polysilicon material production technology has long been in the United States, Japan, Germany and other three countries 7 companies in the hands of 10 factories, the formation of technology blockade, the market monopoly situation. The demand for polysilicon is mainly from semiconductors and solar cells. According to the different requirements of purity, divided into electronic and solar level. Among them, for the electronic grade polysilicon accounted for about 55%, solar grade polysilicon accounted for 45%, with the rapid development of photovoltaic industry, solar cell demand for polysilicon growth rate higher than the development of semiconductor polysilicon, is expected to 2008 solar polysilicon Demand will exceed the electronic grade polysilicon. In 1994 the world's total output of solar cells is only 69MW, and in 2004 was close to 1200MW, in a short period of 10 years, an increase of 17 times. Experts predict that the solar PV industry will overtake nuclear power as one of the most important basic energy sources in the first half of the 21st century.

Crystal silicon panels: polycrystalline silicon solar cells, monocrystalline silicon solar cells.

Amorphous silicon panels: thin film solar cells, organic solar cells.

Chemical Dyestuffs: Dye Sensitive Solar Cells.

Flexible solar cells
