The mono solar panel company will introduce to you: At present, crystalline silicon materials (including polycrystalline silicon and monocrystalline silicon) are the most important photovoltaic materials, with a market share of more than 90%, and will still be the main source of solar cells for a long period of time in the future. mainstream materials.

The production technology of polysilicon materials has been in the hands of 10 factories of 7 companies in 3 countries including the United States, Japan and Germany for a long time, forming a situation of technology blockade and market monopoly. The demand for polysilicon mainly comes from semiconductors and solar cells. According to different purity requirements, it is divided into electronic grade and solar grade. Among them, electronic-grade polysilicon accounts for about 55%, and solar-grade polysilicon accounts for 45%. With the rapid development of the photovoltaic industry, the demand for polysilicon for solar cells is growing faster than the development of semiconductor polysilicon. Demand will outstrip electronic-grade polysilicon. In 1994, the total output of solar cells in the world was only 69MW, but in 2004 it was close to 1200MW, an increase of 17 times in just 10 years. Experts predict that the solar photovoltaic industry will surpass nuclear power to become one of the most important basic energy sources in the first half of the 21st century.
