A novel hybrid solar-thermoelectric device on Ti-based metal oxides, TiO2 and SrTiO3, has been investigated. SrTiO3 thin films were deposited by RF sputtering in the presence of Ar sputtering gas without oxygen gas. X-ray diffraction pattern indicates that annealed thin films were partially polycrystalline and/or amorphous. A dye-sensitized solar cell, whose electrode is made of thermoelectric material SrTiO3:Nb single crystal, shows photovoltaic and thermoelectric effects.
