On April 19, Zhang Xiutao, general manager of Qingdao Gaoce Technology Co., Ltd., and his entourage visited Tongwei for a discussion and exchange. Dr. Xing Guoqiang, Chief Technology Officer of Tongwei Photovoltaic, Ma Zicheng, Deputy Chief Engineer of Sichuan Yongxiang Photovoltaic Technology Co., Ltd. , Tongwei Solar Photovoltaic Technology Center responsible persons warmly received and discussed.

Discussion

At the symposium, General Manager Zhang Xiutao said that Gaoce is an enterprise that values R&D technology and R&D talents. The company focuses on the field of cutting hard and brittle materials. Its business covers cutting equipment, cutting consumables and silicon wafer cutting and processing services. It has advanced photovoltaic Cutting equipment and specialized slicing technology will be responsible for slicing equipment, technology development and services. This time, Gaoce has reached a strategic partnership with Tongwei. Gaoce will give full play to its own experience and advantages, work together with Tongwei to be a link in the industrial chain, continue to improve the quality of silicon wafers through technological and product innovation, and promote the downturn of the photovoltaic industry chain. Increase efficiency and realize high-quality development of the industry.

Dr. Xing Guoqiang said that relying on the development strength of upstream silicon materials and midstream batteries, Tongwei follows the development trend of the industry and cuts into the component link to comprehensively develop the synergistic advantages of the industrial chain. This signing is in line with Tongwei's long-term integrated development strategy. At present, Tongwei has a production capacity of 230,000 tons of high-purity crystalline silicon in the upstream. By the end of 2022, the production capacity of solar cells has reached 70GW, and the production capacity of modules has reached 14GW. It will form a production capacity of 800,000-1 million tons of high-purity crystalline silicon, and Tongwei Solar will form a production capacity of 130-150GW, creating a more competitive photovoltaic industry structure. The company continues to provide high-quality and affordable high-purity crystalline silicon and solar cell products for partners in the industry chain. While promoting the steady development of the company's photovoltaic business, it continues to make more contributions to the development of the industry.

During the symposium, the three parties jointly signed a framework cooperation agreement for the joint laboratory project. In the future, the three parties will give full play to their respective technological advantages and resource advantages in the industrial chain, "From crystal pulling, slicing, battery and module application development and other links, around ultra-thin silicon wafer cutting, heterojunction cost reduction and crystalline silicon cutting surface In-depth cooperation and data sharing have been achieved in morphology research and other aspects, and joint laboratories have been established to jointly develop cutting-edge projects, promote technological progress, and accumulate new kinetic energy for the high-quality development of photovoltaic industry clusters.
