A novel planar acceptor IDT-2BR was designed and synthesized. Polymer solar cells (PSCs) based on P3HT:IDT-2BR blended films gave power conversion efficiencies of up to 5.12%, which are much higher than that of PC61BM-based control devices (3.71%) and the highest values reported for P3HT-based fullerene-free PSCs.NSFC [91433114, 51261130582, 21504006, 21534003]; 973 Project [2011CB808401]; President's Undergraduate Research Fellowship of Peking University; Office of Science, Office of Basic Energy Sciences of the U.S. Department of Energy [DE-AC02-05CH11231]SCI(E)EIARTICLExwzhan@pku.edu.cn113215-3221
