Abstract
The effect of GdVO4:Dy3? luminescent film as down converter material on the efficiency of dye sensitized solar cell (DSSC) was investigated. For this urpose, GdVO4 nanoparticles doped with lanthanide were synthesized by hydrothermal method and the effect of different parameters such as emperature, reaction time, concentration of dopant and annealing regime on their morphology and photoluminescence (PL) properties were studied. he ultraviolet–visible (UV–Vis) and PL spectroscopy studies indicated that GdVO4 nanoparticles could be used as luminescent down conversion (DC) nd UV filters. Considering the decrease of chemical stability of dye sensitized solar cells under UV radiation, nanoparticles of GdVO4: Dy3?, onstructed as a UV filter and the luminescent DC were used to increase the cell efficiency of DSSC. The efficiency of DSSC increased by 10.30 % using ilm of nanoparticles on the back surface of the photo electrode (PE) and by 2.69 %, when the nanoparticles were used to prepare the PE of DSSC, ompared with a DSSC lacking GdVO4:Dy3?.
