Abstract: Abstract Two donor-acceptor (D-A) copolymers (PMT-FBT and PET-FBT) with alkoxythiophene-substituted benzo[1,2-b:4,5-b′]dithiophene as donor unit and difluorobenzothiazole as acceptor unit, were synthesized and employed as donor material for polymer solar cells (PSCs). The comparative study showed… read more here.
