JinkoSolar’s Perovskite Tandem Solar Cell Based on N-type TOPCon Sets New Record with Conversion Efficiency of 33.24%

SHANGRAO, China, May 31, 2024 /PRNewswire/ — JinkoSolar Holding Co., Ltd. (the “Company,” or “JinkoSolar”) (NYSE: JKS), one of the largest and most innovative solar module manufacturers in the world, today announced a significant breakthrough in the development of its N-type TOPCon-based perovskite tandem solar cell. Tested by the Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences, the cell achieved an impressive conversion efficiency of 33.24%, a significant leap beyond JinkoSolar’s previous record of 32.33% for the same type of tandem cells. This is a remarkable achievement, breaking the world record in efficiency and power output for PV products an impressive 26 times.

The record-breaking perovskite tandem solar cell employed Jinko’s n-type high-efficiency monocrystalline TOPCon solar cell as the bottom cell. This breakthrough in conversion efficiency for the perovskite/TOPCon tandem solar cell has been achieved through various materials and technology innovations including ultra-thin poly-Si passivated contact technology, novel light-trapping technology, intermediate recombination layer with high light transmittance and high carrier mobility, and efficient surface passivation technology using hybrid materials. This achievement demonstrates the compatibility of TOPCon as a mainstream solar cell technology with the next-generation perovskite/silicon tandem cell technology, breaking the efficiency limit of single-junction silicon solar cell.

As a leading company in the photovoltaic industry, JinkoSolar invests substantial R&D annually for technological innovation, continuously building up its patent portfolio and breaking world records in R&D achievements. To date, JinkoSolar has applied for over 3,800 global patents and has been granted more than 3,500, providing higher efficiency and better value energy solutions to the global solar photovoltaic market with ongoing technological breakthroughs. 

Dr. Jin Hao, CTO of JinkoSolar, said, “This milestone breakthrough once again highlights JinkoSolar’s determination to continuously push the boundaries through strong technological innovation capabilities. It also lays a solid technical foundation for the Company’s continuous development. We believe that, as we continue to deepen our scientific research and technology, we will contribute to building a greener and more sustainable new energy structure.”
