According to EnergyTrend, the Ecological Environment Bureau of Chuzhou City, Anhui Province issued the "SolarSpace (Chuzhou) Co., Ltd. High-efficiency large-size photovoltaic cell technical transformation project Announcement of acceptance of Ecological Environmental Impact Report.
According to the environmental impact assessment report, in July 2022, SolarSpace’s holding subsidiary SolarSpace (Chuzhou) Co., Ltd. In the expansion area of Langya Economic Development Zone, Chuzhou City Investment of approximately RMB 10.5 billion Construction of a high-efficiency photovoltaic cell project with an annual output of 16 GW, the project will be implemented in two phases, with each phase having an annual production capacity of 8 GW. The independent completion environmental protection acceptance will be completed in August 2023 and February 2025 respectively.
This technical transformation project mainly targets the process and equipment upgrade of the existing photovoltaic cell production line, with a total investment of RMB 800 million. Specifically, battery workshop 1 It is planned to transform all 16 existing TOPCon production lines into TBC type production lines. The entire line of equipment and related wet, high temperature, coating, screen, testing and other auxiliary equipment will be technologically upgraded, some of the original equipment will be eliminated, and LP, photolithography, dicing, inkjet and other equipment will be added.
Battery workshop 2 Upgrade and transform the existing 16 TOPCon production lines. By introducing advanced processes such as back laser technology, edge passivation technology, and silver-coated copper technology to reduce long-wavelength light parasitic absorption and repair cell cutting edge defects, it is expected that the battery conversion efficiency will increase by more than 0.2%, and the module efficiency will achieve a comprehensive gain of more than 0.3%. The module power will reach more than 740W, exceeding the second-level energy efficiency standard. At the same time, the amount of precious metal silver will be reduced, effectively reducing manufacturing costs and enhancing product price competitiveness.
This technical transformation mainly focuses on the process and equipment upgrade of the existing photovoltaic cell production line. After the technical transformation is completed, SolarSpace will further adjust the technical structure of the existing battery production line.
