摘要: 采用水热法制备不同浓度CeO2掺杂TiO2薄膜,并以其为光阳极组装染料敏化太阳能电池(DSSCs),同时考察不同CeO2掺杂浓度对TiO2光阳极的光电转换效率的影响。通过X射线衍射(XRD)、扫描电镜(SEM)、透射电镜(TEM)X射线光电子能谱(XPS)等测试手段、紫外可见漫反射谱(UVVis DRS),对制得的光阳极薄膜进行晶体结构、表面形貌、微观结构、元素价态以及光学特性的表征,并对组装的DSSCs进行光电性能测试。结果表明:适量浓度的CeO2掺杂可提高太阳能电池中的短路电流与光电转换效率;与纯TiO2光阳极相比,0015 mol·L-1 Ce(NO3)3修饰的CeO2/TiO2光阳极的光电转换效率从244%提高到591%

Abstract: CeO2/TiO2 photoanodes with different CeO2 doping concentrations were prepared via a method of hydrothermal treatment and the photoanodes were sensitized with N719 dye to assemble dyesensitized solar cells (DSSCs). Multiple research techniques including XRD, SEM, HRTEM, XPS and UVVis DRS were employed to characterize the crystal structure, morphology, microstructure, chemical composition and optical properties of the fabricate samples. The photovoltaic measurement indicated that with a proper doping concentration, the cells photovoltaic performance was improved compared with the pristine TiO2 based cell. Among the samples with different doping concentrations, the sample CeO2/TiO2 modified with 0015 mol·L-1 Ce(NO3)3 solution exhibited the best power conversion efficiency (591%), which was improved compared with the pristine TiO2 sample (244%).

Key words: TiO2 thin film; CeO2 doping; dyesensitized solar cell; photovoltaic performance
