Abstract: Polymer solar cells have been a subject of great interests, because of their advantages such as low cost，light weight and ease of large-area processing. Being a technique of depositing polymer film, inkjet printing has advantages of low wastage, high efficiency and flexible patterning process and has been used to fabricate polymer solar cells with great potential. The research progress of the polymer solar cells, inkjet printing and polymer solar cells fabricated by inkjet printing is reviewed. Meanwhile, the research trends and perspective of polymer solar cells, inkjet printing and polymer solar cells fabricated by inkjet printing are proposed.
