JinkoSolar’s High-efficiency N-Type Monocrystalline Silicon Solar Cell Sets New World Record with Maximum Conversion Efficiency of 25.7%

SHANGRAO, China, April 27, 2022 — JinkoSolar Holding Co., Ltd. (“JinkoSolar” or the “Company”) (NYSE: JKS), one of the largest and most innovative solar module manufacturers in the world, today announced that it has achieved a major technical breakthrough for its 182 mm high-efficiency N-type monocrystalline silicon solar cell. JinkoSolar has set a new world record again with the maximum solar conversion efficiency of 25.7% for its large-size monocrystalline silicon TOPCon solar cell. This result has been independently confirmed by the National Institute of Metrology, China (“NIM”).

The record-breaking monocrystalline silicon solar cell was fabricated on a high quality CZ Mono-Si substrate. High temperature gettering, advanced diffusion, semi-transparent metallization, JinkoSolar’s self-developed HOT technologies, and a series of material upgrades were integrated into the cell process to set this new world record for maximum conversion efficiency of 25.7%, compared with the record set last October reaching 25.4%.

Dr. Jin Hao, CTO of Jinko Solar Co., Ltd., commented, “We are very proud to set another world record for the N-type monocrystalline silicon solar cell. It is a major breakthrough for our N-type TOPCon cell technology and an important milestone in our development of innovative products and solutions. We are constantly investing in technology upgrades to achieve cost-effective mass production, and increase the competitiveness of our N-type products in the market. Our global clients trust our cutting-edge technology and reliable supply chain. We are well-positioned to lead the industry with innovative products and provide our customers with higher returns on their projects.”
