JinkoSolar tops 26 percent efficiency with TOPCon silicon solar cell


JinkoSolar Holding Co. hit as new record milestone with its 182 mm high-efficiency N-type monocrystalline silicon solar cell: a maximum solar conversion efficiency of 26.1%. This result for its 182 mm and above large-size monocrystalline silicon TOPCon solar cell has been independently confirmed by the National Institute of Metrology, China.

“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,” stated Jin Hao, CTO of Jinko Solar Co.

The R&D department has developed interface defect passivation, highly transparent poly silicon film and ultra thin metallization technologies based on laser dopped selective emitter, which are 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%.

JinkoSolar has 14 productions facilities globally, 21 overseas subsidiaries in Japan, South Korea, Vietnam, India, Turkey, Germany, Italy, Switzerland, the United States, Mexico, Brazil, Chile, Australia, Canada, Malaysia, UAE, and Denmark, and global sales teams in China, the United States, Canada, Germany, Switzerland, Italy, Japan, Australia, Korea, India, Turkey, Chile, Brazil, Mexico and Hong Kong, as of June 30, 2022.
