Trina Solar Co. Ltd. announced today that its State Key Laboratory (SKL) of PV Science and Technology (PVST) of China has set a new world record of 24.58% for a high-efficiency n-type mono-crystalline silicon (c-Si) i-TOPCon solar cell.
The record-breaking bifacial solar cell was fabricated on a large-sized 244.62 cm2 wafer with a low-cost industrial process of advanced i-TOPCon (Industrial Tunnel Oxide Passivated Contact) technologies, having a front boron emitter and a rear full-area passivating contact. The bifacial solar cell reached a total-area front side efficiency of 24.58%, without using any dedicated aperture during the illumination. This result has been independently confirmed by the ISFH CalTeC in Germany.
