Abstract

Abstract : Small‐molecule nonfullerene‐based tandem organic solar cells (OSCs) are fabricated for the first time by utilizing P3HT:SF(DPPB)4 and PTB7‐Th:IEIC bulk heterojunctions as the front and back subcells, respectively. A power conversion efficiency of 8.48% is achieved with an ultrahigh open‐circuit voltage of 1.97 V, which is the highest voltage value reported to date among efficient tandem OSCs.
