Trina Solar, the global provider of PV and smart energy total solutions, announced today that its State Key Laboratory of PV Science and Technology in China has set a new world record for a high-efficiency n-type mono-crystalline silicon (c-Si) i-TOPCon solar cell.

New efficiency record for a mono cell
The latest efficiency world record has been achieved in Trina Solar's State Key Lab of PV Science and Technology.

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)
