量子点敏化太阳能电池（quantum dot-sensitized solar cells，QDSSCs）由于其理论转化效率高（44%）、带隙可调、价格低廉和稳定性好等优点引起了广泛关注。本文就QDSSCs的结构组成、工作原理、量子点（quantum dots，QDs）的合成方法、限制效率的因素以及优化方法等进行了综述，总结了量子点的两种合成方法即原位沉淀法和非原位沉淀法。与此同时，分析了目前影响QDSSCs效率的主要因素，如电子-空穴对的复合、光阳极结构不完善、电解质性能不佳等，最后对如何提高 QDSSCs 光电转化效率的研究重点和方向进行了展望，指出可通过改性量子点敏化剂、优化光阳极半导体及改善量子点与半导体间的界面特性等方法提高转换效率。

Quantum Dot-Sensitized Solar Cells (QDSSCs) have been drawing much more attention due to their high efficiency,tunable band gap,low cost and good stability. This paper reviews the latest research progress in QDSSCs,including the structure of QDSSCs,the basic working principle of QDSSCs,the synthesis methods of quantum dots(QDs),the limiting factor of conversion efficiency and the optimization methods. Two preparation methods of QDs are also summarized asin-situ synthesis andex-situsynthesis. Meanwhile,the effects of the recombination of electrons and holes,defective structure of photoelectrode and deficient functions of electrolyte on the efficiency of QDSSCs are analyzed,and the future research of QDSSCs is also prospected. Measures to improve the efficiency of QDSSCs,including QDs modification,photoelectrode structure optimization,and the modification of the interface between QDs and photoelectrode,are pointed out.
