Tailoring intra-molecular coupling in BDT-based copolymers to enhance their performance in fullerene-free organic solar cells

20234 citationsOpen accessDebre Berhan University

Abstract

By systematically adding acceptors and π-spacers, the structure of a BDT-based copolymer could be tailored to improve their performance in non-fullerene based organic solar cells. A planar geometry increases the complementarity of the copolymer with ITIC, resulting in an efficiency of more than 8%.
