The module achieved a full-panel conversion efficiency of 29.2% in testing by Germany’s TÜV SÜD and is designed for mass production rather than laboratory-scale use.
Chinese PV manufacturer Trina Solar has unveiled a 907 W n-type TOPCon-perovskite tandem solar module.
According to the company, the module achieved a full-panel conversion efficiency of 29.2% in testing by Germany’s TÜV SÜD. The product is reportedly designed for mass production, rather than a laboratory-scale sample.
The module uses a two-terminal tandem cell architecture combining an n-type TOPCon crystalline silicon bottom device with a perovskite top cell. The design is intended to absorb a broader part of the solar spectrum than conventional single-junction silicon modules.
The module measures 2,384 mm by 1,303 mm and is based on 210 mm wafer technology. It incorporates large-area perovskite film deposition, tunnel recombination contact technology, and high-reliability encapsulation.
