The record-breaking bifacial solar cell was fabricated on a large-sized 244.62 square centimetre 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 per cent, without using any dedicated aperture during the illumination. This result has been independently confirmed by the ISFH CalTeC in Germany.
“We are very delighted to announce the latest achievement from our research team at the State Key Laboratory of PV Science and Technology. To the best of our knowledge, this is the new world record for total area efficiency for a large-area two-side contact silicon solar cell”, said Jifan Gao, the CEO of Trina Solar. “The excellent R&D results lays a solid foundation for Trina Solar to provide new differentiated high-end PV modules and solutions to our customers.” (mfo)
