Abstract

Abstract : An efficient bulk heterojunction all‐small‐molecule organic solar cell composed of a high‐performance small‐molecule donor and a self‐assembling nonfullerene acceptor is demonstrated. Favorable nanoscale phase separation and enhanced charge carrier generation with transport in this donor–acceptor system assures a maximum power conversion efficiency of 5.4%.
