JinkoSolar’s 182 mm TOPCon Module Reaches Conversion Efficiency of 23.86%

SHANGRAO, China, November 15, 2022 — 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 that following the record of maximum solar conversion efficiency of 26.1% recently set by its 182 mm and above large-size monocrystalline silicon TOPCon solar cell, the maximum solar conversion efficiency of JinkoSolar’s 182 mm N-type module reached 23.86%. The result was independently tested and confirmed by TÜV Rheinland, one of the world’s leading testing service providers on internationally recognized safety and quality standards.

The module adopted JinkoSolar’s latest TOPCon cell technology and advanced welding and packaging technology and achieved conversion efficiency of 23.86% for the first time for 2 mm2 above large-size solar modules. The advanced welding and packaging technology effectively reduces the internal resistance loss of the module, while significantly improving conversion efficiency. In addition, this lab result has the practical foundation to be introduced into mass production, and technically set the direction for mass production of subsequent advanced products.

Dr. Hao Jin, Chief Technology Officer of JinkoSolar Co., Ltd., commented, “We are pleased to make another breakthrough in module conversion efficiency, leveraging our accumulated experience and continuous efforts in N-type technology R&D and mass production. It is both recognition and incentive for our R&D capabilities. We will drive industrial progress through constant technical upgrades in product structure, materials and processes, catering to clients’ demands for high-efficient and more reliable N-type products. As the advantages of N-type products are further recognized by the market, we are confident to lead the industry with increasing penetration and cost-effective performance.”
