Abstract Polymer solar cells ( PSCs) posed of a blend film of conjugated polymer donor and soluble
fullerene derivative acceptor sandwiched between an ITO transparent electrode and a metal electrode. PSCs have drawn
broad research interests in recent years , due to their advantages of simple device structure , low cost , light weight and
possibility to fabricate flexible devices. The donor and acceptor materials in the devices play the crucial role for the
photovoltaic performance of the PSCs. In this article , the recent progress of the conjugated polymer donor and fullerene
acceptor materials is reviewed. Furthermore , the conjugated polymer acceptor materials and D A double cable polymer
photovoltaic materials are also introduced briefly. In the introduction of conjugated donor materials , the emphasis is put
in the polythiophene derivatives and benzothiodiazole containing narrow bandgap D A copolymers.
Key words polymer solar cells ; conjugated polymer photovoltaic materials ; fullerenes ; polythiophene ; low band
