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.
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.
