A research team from the Ningbo Institute of Materials Technology and Engineering has achieved a power conversion efficiency of 26.09% in industrial-grade TOPCon silicon solar cells, significantly reducing silver consumption. By employing a high-precision steel-stencil printing method and a localized polysilicon structure, the team enhanced electrical contact and bifacial performance, addressing cost constraints in the photovoltaic sector. These innovations position TOPCon technology for increased efficiency and lower-cost production at scale, crucial for reducing silver demand in the industry.
