Photovoltaic Silicon Material Manufacturing Project (Phase II 50,000 T/Y High-Purity Polycrystalline Silicon Project) of Inner Mongolia Tongwei High-Purity Polycrystalline Silicon Co., Ltd.

Tongwei Group is a large multinational conglomerate that focuses on green agriculture and green energy. It is a key national leading enterprise in agricultural industrialization. In the field of new energy, Tongwei has become a vertically integrated photovoltaic enterprise with independent intellectual property rights, covering the production of high-purity polysilicon in the upstream, the production of high-efficiency solar cells and modules in the midstream, and the construction and operation of photovoltaic power plants in the downstream. It has formed a complete photovoltaic new energy industry chain. In the upstream of the new energy industry chain, Tongwei’s subsidiary Yongxiang Co., Ltd. has three major high-purity polysilicon production bases in Leshan, Sichuan, Baotou, Inner Mongolia, and Baoshan, Yunnan. It has built globally leading production lines with large-scale, low comprehensive energy consumption, technological integration, and high-quality products. By the end of 2023, Yongxiang Co., Ltd.’s high-purity polysilicon production capacity will exceed 380,000 tons, leading globally. The core technology of high-purity polysilicon has been successfully applied in Yongxiang New Energy Phase II, Tongwei Yunnan Phase I, and Tongwei Inner Mongolia Phase II projects.

Inner Mongolia Tongwei High-Purity Polysilicon Co., Ltd. is committed to becoming an industry benchmark in high-purity polysilicon and photovoltaic industries. The company’s high-purity polysilicon products, including polycrystalline silicon, monocrystalline silicon, and electronic-grade polycrystalline silicon, are widely used in solar panels, flat panel displays, semiconductor materials, and other fields.
