In order to obtain higher power conversion performance in dye-sensitized solar cells, phthalocyanine compounds (ZnPc-1 and ZnPc-2) containing electron donor methoxy groups and aldehyde groups as anchors were synthesized in this study. The photovoltaic and electrochemical properties of these compounds were studied and their applicability as photosensitizers in DSSCs was investigated. The photovoltaic cell efficiencies (PCE) of the devices were in the range of 0.43–0.76 % under simulated AM 1.5 solar irradiation of 100 mW/cm2. Considering the photovoltaic performance of the produced DSSC devices, the anchor group and the chelate effect, it was observed that the efficiency increased, respectively, ZnPc-1 < ZnPc-2. The highest PCE value of 0.76 % was obtained with asymmetric ZnPc-2 based DSSC under. It has been explained that methoxy groups are electron donors and contribute to intramolecular electron mobility and that better electron transfer with single aldehyde anchor increases cell efficiency. In addition, the increase in the number of methoxy groups with known donor properties on the molecule also contributed to the increase in cell efficiency by increasing electron transfer. All compounds synthesized were characterized using FTIR, UV-vis and MS spectroscopic data.

酞菁化合物中供体和锚定基团对染料敏化太阳能电池效率影响的研究

为了在染料敏化太阳能电池中获得更高的功率转换性能，本研究合成了含有电子供体甲氧基和醛基作为锚定物的酞菁化合物（ZnPc-1 和 ZnPc-2）。研究了这些化合物的光伏和电化学性质，并研究了它们作为光敏剂在 DSSC 中的适用性。在 100 mW/cm2 的模拟 AM 1.5 太阳辐射下，器件的光伏电池效率 (PCE) 在 0.43-0.76% 的范围内。考虑到生产的 DSSC 器件的光伏性能、锚定基团和螯合效应，观察到效率分别增加，ZnPc-1 < ZnPc-2。使用不对称 ZnPc-2 基 DSSC 获得了 0.76% 的最高 PCE 值。已经解释了甲氧基是电子供体并有助于分子内电子迁移率，并且与单个醛锚更好的电子转移增加了电池效率。此外，分子上具有已知供体特性的甲氧基数量的增加也有助于通过增加电子转移来提高电池效率。所有合成的化合物都使用 FTIR、UV-vis 和 MS 光谱数据进行了表征。
