Dye-sensitized solar cells (DSSCs) have been considered one of the most promising candidates for renewable energy devices because of their high efficiency and low production cost. Nano-particles of pure TiO2 consisting of a semiconductor thin film in DSSC are one of the most useful materials in use until now. however, pure TiO2 has disadvantage, its electron transfer is not easy. A lot of works have been done to improve the photo kinesis of TiO2 by doping with various metal ions. This study examined the photoelectric conversion efficiency of dye-sensitized solar cells when nanometer sized Y (0.1, 0.5, and 1.0 mol-%)-TiO2 prepared using a solvothermal method was employed as a working electrode material. |
