Abstract

This research paper presents a systematic study on the preparation of ceria-doped ZnO (CDZ) nanomaterials for use as photoanodes in dye-sensitized solar cells (DSSCs). It introduces a novel organic dye, CCTRh, characterized by a D-A-π-A configuration and free from metallic components. The study involved doping ZnO with varying concentrations of CeO₂ (3%, 4%, and 5%) and characterizing the resulting CDZ using various techniques, including UV–Vis spectroscopy, photoluminescence, Density Functional Theory (DFT), electrochemical investigations, X-ray diffraction, scanning electron microscopy, energy-dispersive X-ray spectroscopy, and Brunauer-Emmett-Teller (BET) analysis. The findings indicate that the 4% CDZ exhibited the most optimized properties, achieving an efficiency of 2.54% when paired with the CCTRh dye, thus demonstrating the potential of CDZ as an effective photoanode material for DSSC applications.

用氰吡啶染料敏化铈掺杂ZnO光阳极的染料敏化太阳能电池研究

本文系统地研究了用于染料敏化太阳能电池（DSSCs）的掺杂氧化锌（CDZ）纳米材料的制备。介绍了一种新型有机染料CCTRh，其结构为D-A-π-A，不含金属成分。该研究涉及用不同浓度的CeO2（3%、4%和5%）掺杂ZnO，并使用各种技术表征所得到的CDZ，包括紫外可见光谱、光致发光、密度泛函数理论（DFT）、电化学研究、x射线衍射、扫描电子显微镜、能量色散x射线光谱和布鲁诺尔-埃米特-泰勒（BET）分析。结果表明，4%的CDZ表现出最优化的性能，当与CCTRh染料配对时，CDZ的效率达到2.54%，从而证明了CDZ作为DSSC应用的有效光阳极材料的潜力。
