November 27– JinkoSolar, the global leading PV and ESS supplier, announced that it has achieved a new world record efficiency of 34.76% for its N-type TOPCon-based perovskite tandem cell, certified by the National PV Metric & Testing Center (NPVM). This result breaks the previous record of 34.22% for this type of tandem cell, marking the 32nd time JinkoSolar has broken a world record for cell efficiency and module power, representing significant progress in next-generation perovskite tandem technology.
This latest breakthrough is attributed to JinkoSolar's systematic innovation in perovskite and tandem technologies. Key advancements include the company's self-developed high-efficiency N-type TOPCon bottom cell, perovskite bottom interface defect passivation, novel perovskite crystallization techniques, and optimized charge vertical transport strategies. This achievement not only demonstrates JinkoSolar's leading R&D capabilities in perovskite technology but also establishes a solid foundation for the industrialization of high-efficiency tandem cells.
"This 34.76% efficiency breakthrough is a milestone for JinkoSolar's R&D system, proving the feasibility and great potential of TOPCon and perovskite tandem technology," said Dr. Hao Jin, Chief Technology Officer of JinkoSolar. "We firmly believe tandem technology will be the next disruptive direction following TOPCon. Our next step is to advance this technology from the laboratory to large-scale application, providing global customers with high-performance, cost-effective modules featuring long lifespan to support the global green energy transition."
