Read MoreA new record! The mass production conversion efficiency of DAH Solar's TOPCon cells has reached 26.05%! The mass production average conversion efficiency of TOPCon cells (PE-poly route) exceeded 26%! On September 3rd, with the superposition application of SE (Selective Emitter) laser doping technology, the mass production average conversion efficiency of DAH Solar TOPCon cells, has reached 26.05%, refreshing the industry record once again, reaching the industry leading level, showing the "DAH speed". On June 9, DAH Solar and SHENZHEN S.C issued the joint announcement, that DAH Solar's TOPCon cells manufacturing base set the climbing record of 97% yield and 25.4% efficiency in just 23 days (not on SE at that time), which attracted high attention from the whole industry. Subsequently, through the continuous optimization of each technical links and materials, by the end of July, the mass production average conversion efficiency of DAH Solar’s TOPCon cells has reached 25.8%. At the beginning of September, with the equiped of laser SE equipment and technology, the conversion efficiency improved by another 0.25%, creating an industry-leading level by 26.05%. DAH Solar has always focused on R&D and organization development.Not only in terms of module and PV system product innovation, we have successfully launched the global patent Full-Screen PV module and the world's first integrated PV system SolarUnit, and also forward-looking developand layout of cells technology, with absolute advantages to achieve the full production of TOPCon cells and the high-speed climbing of conversion efficiency and yield. In addition to that, DAH Solar has also precipitated for many years in terms of crystal pulling and slicing technology, laying a good foundation for further improving the layout of industrial integration.

DAH Solar Plans To Build 7GW TOPCon Silicon Wafer Solar Cell Manufacturing Base in Shanxi
On the morning of June 3, DAH Solar Co., Ltd., Jinzhong Development Zone Management Committee of Shanxi Transformation Comprehensive Reform Demonstration Zone, and China Three Gorges Corporation Shanxi Branch discussed the " DAH Solar 7GW high-efficiency N-type silicon wafer and solar cell production base project" reached the strategic cooperation and formally signed a contract. The project plans to build 7GW of high-efficiency N-type silicon wafers and 7GW of high-efficiency N-type solar cell production capacity, with a total investment of about 2 billion Yuan RMB.
Before the signing ceremony, project-related leaders visited and inspected DAH Solar’s headquarters base and DAH Solar’s TOPCon Manufacturing base. To have the meeting with Xie Shenheng the President of DAH Solar and Bian Chonglei, the CEO of DAH Solar Waiting for the leaders to hold a discussion on this strategic cooperation.
Xie Shenheng, the President of DAH Solar, indicated that DAH Solar's 7GW high-efficiency N-type silicon wafer and solar cell production base project is important for the company to deepen its industrial integration layout. The strategic cooperation between DAH Solar, Jinzhong Development Zone, and Three Gorges Group will further consolidate the company's strategic development foundation in the next five years, which improve the company's integrated industrial layout, and enhance the company's comprehensive competitiveness. The three parties will give full effort to their respective advantages, strengthen in-depth cooperation at the levels of industry, technology, and market, promote the high-quality development of the regional economy, jointly help the photovoltaic industry reduce costs and increase efficiency, and contribute to the achievement of the goal of carbon dioxide emission and carbon neutrality.
