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 $TiO_2$ prepared using a solvothermal method is utilized as the working electrode material. The photoelectric properties of the Y-$TiO_2$ used in DSSCs were studied by frequency-resolved modulated photocurrent/photovoltage spectroscopy. The recombination was much slower in the Y-$TiO_2$-based DSSCs than in the pure $TiO_2$-assembled DSSC. Compared to that using pure $TiO_2$, the energy conversion efficiency was enhanced considerably by the application of Y-$TiO_2$ in the DSSCs to approximately 6.08% for 0.5 mol % Y-$TiO_2$.
