JinkoSolar Holding Co., Ltd., one of the world’s largest and most innovative solar module manufacturers, announced that it has made significant progress in the development of N-type TOPCon-based perovskite tandem solar cells. The cell, independently tested by the Shanghai Institute of Microsystems and Information Technology of the Chinese Academy of Sciences, achieved an impressive conversion efficiency of 33.84%, surpassing JinkoSolar’s previous record of 33.24%. This achievement marks the 27th time JinkoSolar has set a world record for efficiency and power generation for solar power products.
This record-breaking perovskite tandem solar cell utilizes JinkoSolar’s N-type high efficiency monocrystalline TOPCon solar cell as the bottom cell and is powered by significant advances across multiple key technologies. Innovations such as full-area passivation contact technology, perovskite interfacial defect passivation technology, and bulk defect passivation technology have contributed to improving the efficiency of perovskite/TOPCon tandem cells. This result once again breaks the conversion efficiency limit of single-junction crystalline silicon cells. This achievement highlights the compatibility of TOPCon as a mainstream solar cell technology with next-generation perovskite/silicon tandem cell technology and paves the way for new possibilities in the future development of the photovoltaic industry.
Dr. Jin Hao, Chief Technology Officer (CTO) of Jinko Solar Co., Ltd. said: This milestone strengthens our confidence in our ability to achieve further technological advances as we work towards building a greener and more sustainable energy future. ”
