Trina Solar achieves new record of 24.58% efficiency for Mono-crystalline Silicon i-TOPCon Cell

China’s solar modules manufacturer Trina Solar Co. Ltd. announced 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.

Jifan Gao, the CEO of Trina Solar said:

“We are very delighted to announce the latest achievement from our research team at the SKL PVST, to the best of our knowledge, this is the new world record for a TOTAL AREA efficiency for a large-area two-side contact silicon solar cell. The excellent R&D results lays a solid foundation for Trina to provide a new differentiated high-end PV modules and solutions to our customers.”
