摘要
量子点因具有特殊的量子尺寸效应而得到广泛应用,尤其是在聚合物太阳电池中的应用具有独特的优势。列举了量子点常见的合成方法,如有机相合成法、水相合成法、水热法和溶剂热法、微波辅助水热法、微乳液法等;介绍了常见的量子点表面修饰方法,如偶联剂法、配位基交换法及化学反应法等;最后,介绍了表面修饰后的量子点在聚合物太阳电池中的应用,并针对器件效率较低这一问题讨论了提高聚合物/量子点太阳电池效率的方法。
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.
