TW (Tongwei) Solar entered the PV industry in 2006, initially specialising in polysilicon production before going on to establish itself as a world-leading manufacturer, currently creating waves in the high-efficiency PV module sector.
Longi said it has achieved a 26.56% efficiency rating for a gallium-doped, p-type heterojunction solar cell and a 26.09% efficiency rating for an indium-free HJT cell, both based on M6 wafers. Germany’s Institute for Solar Energy Research in Hamelin has confirmed the results.
