Abstract:

2, 9, 16, 23-tetracarboxy zinc phthalocyanine(ZnTCPc)is synthesized and characterized by physicochemical and theoretical methods and it is used as a photosensitizer in dye-sensitized solar cells(DSSC). The excited lifetime, band gap and frontier orbital distribution of ZnTCPc are investigated by fluorescence spectra, cyclic voltammetry and quantum calculation. The results show that the excited lifetime and band gap are 0.1 ns and 1.81 eV, respectively. Moreover, it is found that the highest occupied molecular orbital(HOMO)location is not shared by both the zinc metal and the isoindoline ligands, and the lowest unoccupied molecular orbital(LUMO)location does not strengthen the interaction coupling between ZnTCPc and TiO₂. As a result, the ZnTCPc-DSSC gains a short-circuit current density of 0.147 mA/cm², an open-circuit photovoltage of 277 mV, a fill factor of 0.51 and an overall conversion efficiency of 0.021%.

合成和表征了2, 9, 16, 23-四羧基酞菁锌, 并将其作为光敏染料应用于染料敏化太阳能电池.通过荧光光谱、循环伏安和量化计算等方法分析了该染料的激发态寿命、能级匹配和前线轨道分布等参数及其对电池性能的影响.结果表明:激发态寿命为0.1 ns, 带隙为1.81 eV, HOMO分布未被锌原子和异二氢吲哚配体共享, LUMO分布不能增强染料与二氧化钛表面之间的相互作用;同时因酞菁类染料易聚集, 因此所组装成的电池的短路电流密度为0.147 mA/cm², 开路电压为277 mV, 填充因子为0.51, 效率为0.021%.
