Abstract

Abstract : Phenazine copolymer donors demonstrate an efficiency of 15.14% in nonfullerene organic solar cells. Abstract : Two phenazine copolymer donors P1 and P2 were developed. P1 and P2 have deep highest occupied molecular orbital levels, enhanced light-harvesting capability and good hole mobility. Solar cells based on P2 and a nonfullerene acceptor, Y6, gave a power conversion efficiency (PCE) of 15.14%, which has been the highest value achieved by phenazine-donor-based solar cells to date.
