Abstract
This study examines the photoelectric conversion efficiency of dye-sensitized solar cells (DSSCs) when nanometer-sized Y (0, 0.1, 0.5, and 1.0 mol %)-incorporated TiO2 prepared using a solvothermal method is utilized as the working electrode material. The photoelectric properties of the Y-TiO2 used in DSSCs were studied by frequency-resolved modulated photocurrent/photovoltage spectroscopy. The recombination was much slower in the Y-TiO2-based DSSCs than in the pure TiO2-assembled DSSC. Compared to that using pure TiO2, the energy conversion efficiency was enhanced considerably by the application of Y-TiO2 in the DSSCs to approximately 6.08% for 0.5 mol % Y-TiO2.
