To design sensitizers for dye sensitized solar cells (DSSCs), a series of zinc chlorins with different substituents were synthesized. Novel zinc methyl 3-devinyl-3-hydroxymethyl-20-phenylacetylenylpyropheophorbide-a (ZnChl-1), zinc methyl 20-bromo-3-devinyl-3-hydroxymethylpyropheophorbide-a (ZnChl-2), zinc methyl 3-devinyl-3-hydroxymethyl-pyropheophorbide-a (ZnChl-3), zinc propyl 3-devinyl-3-hydroxymethyl-pyropheophorbide-a (ZnChl-4) were synthesized and their photovoltaic performances were evaluated in dye-sensitized solar cells. Photoelectrodes with a 7 μm thick nanoporous layer and a 5 μm thick light-scattering layer were used to fabricate dye sensitized solar cells. The best efficiency was obtained with ZnChl-2 sensitizer. ZnChl-2 gave a Jsc of 3.5 mA/cm(2), Voc of 412 mV, FF of 0.56 and an overall conversion efficiency of 0.81 at full sun (1000 W m(-2)).
为了设计用于染料敏化太阳能电池(DSSC)的敏化剂,合成了一系列具有不同取代基的二氢卟吩锌。合成了新型的甲基 3-脱乙烯基-3-羟甲基-20-苯基乙炔基焦脱镁叶绿酸-a 锌(ZnChl-1)、甲基 20-溴-3-脱乙烯基-3-羟甲基焦脱镁叶绿酸-a 锌(ZnChl-2)、甲基 3-脱乙烯基-3-羟甲基焦脱镁叶绿酸-a 锌(ZnChl-3)、丙基 3-脱乙烯基-3-羟甲基焦脱镁叶绿酸-a 锌(ZnChl-4),并在染料敏化太阳能电池中评估了它们的光伏性能。使用具有 7μm 厚纳米多孔层和 5μm 厚光散射层的光电极来制备染料敏化太阳能电池。使用 ZnChl-2 敏化剂时获得了最佳效率。在全日照(1000 W m(-2))下,ZnChl-2 的短路电流密度(Jsc)为 3.5 mA/cm²,开路电压(Voc)为 412 mV,填充因子(FF)为 0.56,总转换效率为 0.81。
