26.05%, DAH Solar set a new record of TOPCon cells mass production conversion efficiency!

A 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.
