Quantum dots are applied extensively owe to their quantum size effect, in particular, they display the superiority in polymer-based solar cells. The common synthesis method of quantum dots are listed, for example, orga- nic synthetic approach, aqueous synthetic approach, hydrothermal and solvothermal approach, microwave-assistant hydrothermal approach and micro-emulsion approach. Moreover, the surface modification method of quantum dots such as coupling agent modification, ligand exchange approach and chemical reaction modification are introduced. Fi- nally, the application of quantum dots in polymer-based solar cells are presented, in particular, the key factors influen- cing device efficiency of polymer/quantum dots solar cells are discussed.
