Abstract TiO2/CeO2:Gd photoanodes with different concentrations of CeO2:Gd were fabricated to improve the photoconversion efficiency of a dye-sensitized solar cell (DSSC). The CeO2:Gd nanoparticle-based DSSC showed a photoconversion efficiency of 8.03% with an improvement of 45% compared to that of the conventional TiO2 nanoparticle-based DSSC due to the increased diffuse reflectance of visible light. The TiO2/CeO2:Gd photoanode had higher charge transfer resistance than conventional TiO2 nanoparticle-based photoanode. It is suggested that the improvement in the conversion efficiency results from the enhanced highly favored light scattering and downconversion photoluminescence of the CeO2:Gd nanoparticles.

通过在光阳极中添加 CeO 2 :Gd 纳米颗粒改善染料敏化太阳能电池的光伏性能

摘要 为了提高染料敏化太阳能电池 (DSSC) 的光转换效率，制备了具有不同浓度 CeO2:Gd 的 TiO2/CeO2:Gd 光阳极。由于可见光漫反射率的增加，基于 CeO2:Gd 纳米颗粒的 DSSC 的光转换效率为 8.03%，与传统的基于 TiO2 纳米颗粒的 DSSC 相比提高了 45%。TiO2/CeO2:Gd 光电阳极比传统的基于 TiO2 纳米颗粒的光电阳极具有更高的电荷转移电阻。这表明转换效率的提高是由于 CeO2:Gd 纳米粒子的增强的非常有利的光散射和下转换光致发光。
