10.2% Power Conversion Efficiency Polymer Tandem Solar Cells Consisting of Two Identical Sub‐Cells. (29th May 2013) - You, Jingbi
Abstract Polymer tandem solar cells with 10.2% power conversion efficiency are demonstrated via stacking two PDTP‐DFBT:PC71BM bulk heterojunctions, connected by MoO3/PEDOT:PSS/ZnO as an interconnecting layer. The tandem solar cells increase the power conversion efficiency of the PDTP‐DFBT:PC71BM system from 8.1% to 10.2%, successfully demonstrating polymer tandem solar cells with identical sub‐cells of double‐digit efficiency.
