Abstract

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.

酞菁化合物中给基和锚基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，本研究合成了以电子供体甲氧基和醛基为锚点的酞菁化合物(ZnPc-1和ZnPc-2)。研究了这些化合物的光伏和电化学性能，并探讨了它们作为DSSCs光敏剂的适用性。在模拟100mw /cm2的AM - 1.5太阳辐照下，器件的光伏电池效率(PCE)在0.43 - 0.76%之间。结合所制备的DSSC器件的光伏性能、锚基团和螯合效应，可以观察到效率的提高，分别为ZnPc-1 < ZnPc-2。不对称ZnPc-2基DSSC的PCE值最高，为0.76%。解释了甲氧基是电子供体，有助于分子内电子的迁移，单醛锚定的电子转移更好，提高了细胞效率。此外，分子上已知供体性质的甲氧基数量的增加也有助于通过增加电子转移来提高细胞效率。所有合成的化合物都用FTIR、UV-vis和MS进行了表征。
