Trinasolar, a global leader in smart PV and energy storage solutions, announced that its industrial larger-area perovskite/crystalline silicon tandem solar cell, jointly developed with Huairou Laboratory, has achieved 32.6% efficiency independently certified by Fraunhofer ISE CalLab, setting a new record on 210mm half-cut tandem solar cell. The 3.1m2 industrial standard-sized tandem module, integrated with tandem cells, has delivered a peak power output of 865W certified by TÜV SÜD, also setting a world record for module power.
The breakthroughs in both efficiency and power output demonstrate the successful integration of Trinasolar’s expertise in large-area perovskite/crystalline silicon tandem solar cell manufacturing with Huairou Laboratory’s advances in next-generation perovskite absorber and functional layer materials. The achievement also underscores the close collaboration between an industry-leading company and the national research laboratory in addressing key technical challenges.
“We are pleased to announce two new world records in perovskite/crystalline silicon tandem solar technology through the effective collaboration,” said Dr. Yifeng Chen, vice president at Trinasolar. “The achievements mark a milestone for next-generation high-efficiency photovoltaics, highlighting the technology's enormous potential. Trinasolar will continue leading innovation in tandem solar technology, strengthening our leadership in advanced photovoltaics.”
