The research paper from the University of Chinese Academy of Sciences, in collaboration with industry researchers, examined tunnel oxide passivating contact solar cells. It applied an integrated front and rear optimization approach. It analyzed crystalline silicon photovoltaics, where TOPCon technology had become the dominant industrial solution. The study addressed efficiency, manufacturing cost, and bifaciality constraints in industrial production. A front-side steel-stencil printing process was used instead of conventional screen printing to form narrower fingers and reduce silver consumption. An optimized silver paste formulation improved the silver–silicon interface and reduced contact resistivity. On the rear side, a laser-patterned local polysilicon contact design reduced parasitic absorption while maintaining carrier transport. The combined strategy achieved a certified efficiency of 26.09% on industrial M10 wafers with bifaciality of around 90%.
