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.
