Research Abstract

Fully conjugated donor-acceptor block copolymers were synthesized for the candidate of non-fullerene acceptor materials. The obtained block copolymers showed the good acceptor and wide light-harvesting properties. The all-polymers solar cells, in which the active layers were respectively prepared from poly(3-hexylthiophene) and the obtained block copolymers as donor and acceptor materials, achieved the power conversion efficiency of 1.6%. These results demonstrated that fully conjugated donor-acceptor block copolymers had a huge potential for the non-fullerene acceptor material.
