At present, the crystalline silicon materials (including polycrystalline and monocrystalline silicon) is the main photovoltaic material, its market share of over 90%, and in the future a long time also is still the mainstream of solar cell materials. Polysilicon material production technology for a long time to master in three countries such as America, Japan, Germany into the hands of seven companies 10 factories, forming technology blockade, the condition of market monopoly. Polysilicon demand mainly comes from the semiconductor and solar cells. According to the requirements of the purity is different, divided into electronic level and solar energy. Among them, to the electronic level polysilicon accounts for about 55%, solar energy polysilicon (45%), with the rapid development of photovoltaic industry, the demand for polysilicon solar cell is growing faster than the development of semiconductor polysilicon, more than 2008 solar polysilicon demand expected to electronic grade polysilicon. Only 69 mw solar cell production worldwide in 1994, and is close to 1200 mw in 2004, increased by 17 times in just a decade. Experts predict solar photovoltaic industry in the 21st century first half will become one of the most important foundation energy than nuclear power.
