Industrial solar cells achieve 26.09% efficiency with reduced silver use and better bifacial performance

A research team led by Prof. Ye Jichun from the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences, in collaboration with partners, has proposed a synergistic technical solution enabling industrial tunnel oxide passivating contact (TOPCon) solar cells to simultaneously achieve high efficiency, low cost, and excellent bifacial power generation performance.
