May 28 (Renewables Now) - Trina Solar has achieved a record-high 24.58% conversion efficiency for an n-type mono-crystalline silicon (c-Si) i-TOPCon solar cell, the Chinese photovoltaics (PV) maker said today.
The result was reached at the State Key Laboratory of PV Science and Technology of China (SKL PVST). According to the Chinese firm, this is the highest total area efficiency level in the world set for a large-area two-side contact silicon solar cell. No dedicated aperture was used during the illumination.
The record-setting bifacial PV cell was fabricated on a large-sized 244.62 sq cm wafer with advanced i-TOPCon (Industrial Tunnel Oxide Passivated Contact) technologies.
The efficiency has been confirmed by The Solar Cells Laboratory of the Calibration and Test Center (CalTeC) at the Institute for Solar Energy Research (ISFH) in Germany. "The excellent R&D results lays a solid foundation for Trina to provide new differentiated high-end PV modules and solutions to our customers," said Jifan Gao, Trina Solar’s CEO.
