我们设计并合成了用于染料敏化太阳能电池的新型Zn（II）-卟啉衍生物。该衍生物在卟啉衍生物的5，10，15-内消旋位上将三苯胺侧基的给电子基团引入氰基取代的（[TPA]Zn-Por-CN 1）或未取代的二苯乙烯部分（[TPA] Zn-Por 1）中，并在20-内消旋位上引入羧酸基团。通过1H NMR、FT-IR、UV-vis吸收光谱、EI-mass、MALDI-TOF质谱等表征了它们的结构。用循环伏安法研究了它们的电化学性能。这些Zn（II）-卟啉衍生物已被用于制造染料敏化太阳能电池的基础上I-/I2液体电解质作为染料敏化剂和它们的设备性能进行了评估，通过比较与标准的Ru（II）络合物染料。[TPA]Zn-Por-CN 1显示出比[TPA] Zn-Por 1更高的功率转换效率，这是由于在435 nm附近具有更宽的吸收带。[TPA]Zn-Por-CN 1的DSSC的短路光电流密度（Jsc）、开路电压（Voc）、填充因子（FF）和功率转换效率（η）分别被评估为Jsc = 6.3mA·cm-2、Voc = 0.737V、FF = 0.683和η = 3.1%。
We have designed and synthesized novel Zn(II)-porphyrin derivatives for dye-sensitized solar cells. The derivatives incorporate the electron-donating group of a pendant triphenylamine into cyano-substituted ([TPA]Zn-Por-CN1) or non-substituted stilbene moiety ([TPA]Zn-Por1) in the 5,10,15-meso-position and carboxylic acid group in the 20-meso-position in a porphyrin derivative. Their chemical structures were characterized by 1H NMR, FT-IR, UV-vis absorption, EI-mass, and MALDI-TOF mass spectroscopies. Their electrochemical properties were studied by cyclic voltammetry measurement. These Zn(II)-porphyrin derivatives have been used to fabricate dye-sensitized solar cells based on I-/I2 liquid electrolytes as dye sensitizers and their device performances were evaluated by comparing with that of a standard Ru(II) complex dye. [TPA]Zn-Por-CN1 showed higher power conversion efficiency than that of [TPA]Zn-Por1, due to a broader absorption band around 435 nm. Short-circuit photocurrent density (Jsc), open-circuit voltage (Voc), fill factor (FF), and power conversion efficiency (η) of DSSC for [TPA]Zn-Por-CN1 were evaluated to be Jsc = 6.3 mA.cm-2, Voc = 0.737 V, FF = 0.683, and η = 3.1%, respectively.
