      PV Intelligent Manufacturing  

      After 10-year rapid development in the PV new energy industry since 2006, Tongwei has become a vertically integrated PV enterprise engaging in the upstream production of high-purity crystalline silicon, production of high-efficiency solar cells, and the construction and operation of PV power stations at terminals. It has formed a complete PV new energy industry chain with independent intellectual property rights, being an important participant and a major driving force in the development of PV new energy industry in China or even in the world.

      YONGXIANG CO.,LTD.

      As a large private science and technology enterprise subordinated to Tongwei, Yongxiang Co., Ltd. has carried out independent innovation in the field of cold hydrogenation, comproportionation, large energy-saving distillation, high-efficiency restoration, exhaust recovery, automatic control of electrical appliances, comprehensive gradient utilization of thermal energy, closed cycle of chlorine and hydrogen elements, and has built a circular economy industrial chain where new energy and chemical industry are fully integrated.

      After technological upgrading for four times, the “Yongxiang Method” developed originally by Yongxiang Co., Ltd. has raised the purity of high-purity crystalline silicon to 99.999999999% (10 to 11 decimal places) and made a global leader when referring to production capacity.
