‘Solar Module Super League’ (SMSL) member, Trina Solar has set a conversion efficiency record of 24.58% for an i-TOPCon (Industrial Tunnel Oxide Passivated Contact) bifacial solar cell using a super-sized 244.62 cm2 wafer.

“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 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.”

PV Tech has been running an annual PV CellTech Conference since 2016. PV CellTech USA, on 13-14 October 2026 is our third PV CellTech conference dedicated to the U.S. manufacturing sector. The events in 2023, 2024 and 2025 were a sell out success and 2026 will once again gather the key stakeholders from PV manufacturing, equipment/materials, policy-making and strategy, capital equipment investment and all interested downstream channels and third-party entities. The goal is simple: to map out PV manufacturing in the U.S. out to 2030 and beyond.
