JinkoSolar, the global leading PV and ESS supplier, today announced that it has achieved a significant breakthrough in the development of its N-type TOPCon-based perovskite tandem solar cell. Independently tested by the Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences, the cell 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 output for PV products.

The record-breaking perovskite tandem solar cell utilizes JinkoSolar’s N-type high-efficiency monocrystalline TOPCon solar cell as the bottom cell, enhanced by significant advancements across multiple key technologies. Innovations such as full-area passivated contact technology, perovskite interfacial defect passivation technology, and bulk defect passivation technology have contributed to the enhanced efficiency of the perovskite/TOPCon tandem cell. The results once again break the conversion efficiency limit of single-junction crystalline silicon cells. This achievement highlights the compatibility of TOPCon as a mainstream solar cell technology with the next-generation perovskite/silicon tandem cell technology, paving the way for new possibilities in the future development of the photovoltaic industry.

Dr. Jin Hao, CTO of Jinko Solar Co., Ltd., said, “Once again, we have achieved remarkable progress in solar cell efficiency as a result of our ongoing investments in R&D and steadfast commitment to excellence. This milestone strengthens our confidence in our ability to achieve further technological breakthroughs as we work toward building a greener and more sustainable energy future.”
