Abstract: A series of narrow-band-gap donor-acceptor conjugated polymers, with quinoxaline derivatives as acceptor units and bithiophene as donor unit, were synthesized. It was found that solubility and device performace of the resultant copolymers were strongly affected by the alkyl chain and fluorine. The synthesized D-A narrow band gap conjugated polymers can be fabricated as active layers for solar cells. The best performance of polymer solar cell was achieved with inverted device structure of ITO/ZnO/Copolymer:PC71BM/MoO3/Ag, which showed an open circuit voltage of 0.55 V, a short-circuit current (Jsc) of 9.56 mA/cm2, and a fill factor of 62.5%, leading to a high power conversion efficiency of 3.31%.
