China’s JinkoSolar Holding Co., Ltd., a global solar module manufacturer, announced a breakthrough in its N-type TOPCon-based perovskite tandem solar cell. The cell achieved a conversion efficiency of 33.84%, verified by the Shanghai Institute of Microsystem and Information Technology. This surpassed the company's previous record of 33.24%. It marked the 27th world record for efficiency and power output in PV products. The cell used N-type high-efficiency monocrystalline TOPCon solar cells. Advancements included full-area passivated contact, interfacial defect passivation, and bulk defect passivation technologies. This demonstrated the compatibility of TOPCon technology with next-generation perovskite/silicon tandem cells. It opened possibilities for further progress in the photovoltaic industry.
