JinkoSolar Sets New Record with Maximum Conversion Efficiency of 26.1%

JinkoSolar Holding Co., Ltd. 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 record again with the maximum solar conversion efficiency of 26.1% for its 182 mm and above large-size monocrystalline silicon TOPCon solar cell. This result has been independently confirmed by the National Institute of Metrology, China (NIM).

The R&D department has developed interface defect passivation, highly transparent poly silicon film and ultra-thin metallization technologies based on laser doped selective emitter. These advanced technologies can be applicable to large area solar cells.

JinkoSolar’s self-developed HOT technologies, and a series of material upgrades were integrated into the cell process to set this new record for maximum conversion efficiency of 26.1%, compared with the record set this April reaching 25.7%.

“We are proud to achieve a major breakthrough in the conversion efficiency of N-type TOPCon cells in less than half a year, breaking the record we have previously set for N-type monocrystalline silicon solar cells,” said Dr. Jin Hao, CTO of Jinko Solar Co., Ltd. “Thanks to the tireless efforts of our talented R&D team for creating this important milestone in the innovation of the company’s products and solutions. We will continue to invest in R&D innovation and mass production capabilities, and to accelerate the pace of industry upgrading for advanced N-type product.”
