LONGi breaks world record for HJT solar cell efficiency twice in one week

Compared with the HJT solar cells on which June's conversion efficiency of 25.26% was achieved, the cells for the latest two world records were optimized. The microcrystalline N window layer was optimized to further increase current density, with a new intrinsic layer structure developed to enhance passivation performance and increase the Voc up to 2mV. The LONGi team also applied a completely indium-free TCO process. The cell was certified by ISFH with an efficiency of more than 25%, providing a valuable reference path for cost reduction in HJT industrialization.

From 25.26% through 25.82% to the latest 26.30%, LONGi has now achieved the rare feat of setting HJT cell efficiency world records three times in six months. Additionally, its N-type and P-Type TOPCon cells have also achieved the world's highest conversion efficiency of 25.21% and 25.19% respectively.
