Brief introduction of Yichang CSG silicon material Co., Ltd.

Yichang CSG Silicon Materials Co., Ltd. is a holding company of CSG, which belongs to the Solar Energy Division, with a total investment of about 6 billion yuan. The company covers an area of 65,438 0.500 mu, and plans to produce 5,000 tons of high-purity polysilicon and 65438±0.60 MW of silicon wafers for solar photovoltaic. By May of 20 10, the production capacity of 1500 tons of high-purity polysilicon, 100 MW silicon wafer and 3400 tons of gas-phase silicon dioxide by-product of polysilicon tail gas has been formed. In just over a year, the quality of solar-grade polysilicon and electronic-grade polysilicon products produced by the company exceeded the national standards, and the production capacity also met the design requirements.

Yichang CSG is the first polysilicon factory in China to realize closed-loop production. In particular, all by-products in the production process are recycled, turning waste into treasure, adopting high-tech nano-materials, and taking the lead in realizing pollution-free production, which truly embodies the concept of environmental protection. With the increasing shortage of fossil energy and global warming, low-carbon economy, energy conservation and renewable energy will be the long-term needs of human social development.

The completion of "CSG Polycrystalline Silicon Production Base" has laid a foundation for CSG to open up the solar photovoltaic industry chain in the future and become a leading domestic solar enterprise. It will form a complete industrial chain of "high-purity polycrystalline silicon materials → silicon wafers → solar cells → solar cells" led by polycrystalline silicon materials, and become an influential supplier in global solar battery industry.
