摘　　要：基于热载流子和多激子效应的新型低成本量子点敏化太阳电池(QDSSCs)的理论,光电转换效率高达66%。然而,目前QDSSCs的效率普遍维持在5%,远低于理论值。因此,对电极较低的催化活性和导电性是限制QDSSCs性能提升的主要原因。设计构筑具有高催化活性和导电性的新型对电极成为提高QDSSCs效率的关键。从增强对电极的催化活性和导电性的角度出发,分别阐述了5类硫化铜复合对电极与QDSSCs效率之间的影响关系,明确了复合对电极的构筑及性能优化是今后提升QDSSCs效率的一个关键研究方向。The theoretical efficiency of novel low-cost quantum dot sensitized solar cells(QDSSCs)based on the effects of hot carrier and multi-exciton is up to 66%.However,the current efficiency of QDSSCs is generally maintained at 5%,which is far lower than the theoretical value.The low catalytic activity and conductivity of the counter electrode are the main bottlenecks for limiting the performance improvement of QDSSCs.Designing and constructing novel counter electrodes with high catalytic activity and electrical conductivity is the key to improve the efficiency of QDSSCs.The relationship between the five types of copper sulfide composite electrode and the efficiency of QDSSCs is described in detail from the perspective of enhancing the catalytic activity and conductivity of the counter electrode.It is clear that the construction and performance optimization of the composite counter electrode is a key research direction to improve the efficiency of QDSSCs in the future.
