Polymer photovoltaic cells are becoming an extremely active research area to meet the urgent need for clean and renewable energy managements 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.In the introduction of conjugated donor materials

the emphasis is put in the polythiophene derivatives and narrow bandgap D-A copolymers.The film optimization and stability are also discussed.In the end

the development prospect of polymer solar cell was given from the perspective of improving cell efficiency.
