ABSTRACT

Y(2)O(3):Er(3+) nanorods are synthesized by means of a hydrothermal method and then introduced into a TiO(2) electrode in a dye-sensitized solar cell (DSSC). Y(2)O(3):Er(3+) improves infrared light harvest via up-conversion luminescence and increases the photocurrent of the DSSC. The rare earth ions improve the energy level of the TiO(2) electrode through a doping effect and thus increase the photovoltage. The light scattering is ameliorated by the one-dimensional nanorod structure. The DSSC containing Y(2)O(3):Er(3+) (5 wt%) in the doping layer achieves a light-to-electric energy conversion efficiency of 7.0%, which is an increase of 19.9% compared to the DSSC lacking of Y(2)O(3):Er(3+).
