Ternary solar cells via ternary polymer donors and third component PC71BM to optimize morphology with 13.15% efficiency

•A PCE over the 13% for ternary PSCs based on ternary polymer donor was achieved.•Morphology studies confirmed that ternaty PSC brought most appropriate phase separation.•A classical ternary strategy could significantly improve charge extraction. The third component played an increasingly significan...
