JinkoSolar says its N-type cell achieves 25.7% efficiency record

Chinese solar module maker JinkoSolar Holding Co Ltd (NYSE:JKS) on Wednesday said it has set a new world record, achieving maximum solar conversion efficiency of 25.7% for its 182 mm high-efficiency N-type monocrystalline silicon solar cell.

The result accomplished by the company’s large-size monocrystalline silicon TOPCon solar cell has been independently confirmed by the National Institute of Metrology, China (NIM). It marks an improvement from the previous record of 25.4% reported in October 2021.

The solar cell was fabricated on a Czochralski (CZ) mono-Si substrate, with the cell process integrating high temperature gettering, advanced diffusion, semi-transparent metallisation, JinkoSolar's self-developed HOT technologies and a series of material upgrades.

“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,” commented Jin Hao, chief technology officer of Jinko Solar Co Ltd.

JinkoSolar has 12 plants globally and an annual capacity of 40 GW for mono wafers, the same for solar cells and 50 GW for solar modules as of March 31, 2022.
