摘 要: 以酞菁分子中的“pull-push”结构为主介绍了近年来酞菁染料分子设计的研究进展,分析总结了“pull-push”基团的改变对电子注入和电子传输,酞菁染料聚集程度和轨道能级,以及染料敏化太阳能电池(dye-sensitized solar cells,DSSCs)效率的影响。良好的“pull”基团应该含有吸电子基或者与TiO2间有强的相互作用,“push”基团应选择空间位阻较大的基团,以提高染料溶解性,减少染料聚集。这2种基团共同作用可有益于激发态电子的注入,促进电子流向半导体,提高效率。
关 键 词: 配位化学;染料敏化太阳能电池;综述;酞菁;染料

Abstract: In this paper, the progress in the development of the research on “pull-push” structure of phthalocyanine dyes was reviewed. Then, this paper summarized the influences of the changes of“pull-push” groups on electron injection and electron transfer, the aggregation of phthalocyanine, the energy level of molecular orbital and the performance of the dye-sensitized solar cells (DSSCs). Good “pull” groups should contain electron-withdrawing groups or have strong interaction with TiO2. In order to improve dye solubility and reduce dye aggregation, the larger steric groups should be selected as “push” groups. Both of the interactions could be benefit to the excitation electron injection to the semiconductor and increased the photoelectric conversion efficiency.
