Abstract

Abstract : A small molecule non-fullerene electron acceptor (SMNFEA), bearing a furan π-spacer and dicyano- n -hexyl rhodanine as flanking groups, was designed and synthesized for organic solar cell applications. Abstract : A small molecule non-fullerene electron acceptor (SMNFEA), bearing a furan π-spacer and dicyano- n -hexyl rhodanine as flanking groups, was designed and synthesized for organic solar cell applications. Organic photovoltaic devices based on FRdCN2 and PTB7-Th polymer donors exhibited a highly improved efficient power conversion efficiency of 10.7%, which is the highest so far for OSCs fabricated from fluorene-core-based SMNFEAs.
