Abstract
Dye-sensitized solar cells have attracted a great deal of attention as next generation solar cells. We report the fabrication of the SnS-nanoparticles-sensitized TiO2 photoelectrodes and their performance in photoelectrochemical solar cells. By controlling the size of SnS at the nano scale, the improvement of the cell performance is expected because of quantum size effect. SnS nanoparicles were deposited on the TiO2 electrodes by the SILAR (successive ionic layer adsorption and reaction) methods reported by B.Ghosh et al1). The TiO2-SnS electrodes were analyzed by various methods, such as UV-vis, SEM, EDX, and so on. Electric power generation with the TiO2-SnS electrodes was confirmed. With increasing the number of coating of SnS, the current density and the conversion efficiency increased.
