Abstract
The invention relates to an electrode material used for organic/inorganic composite battery and provides a simple and low-cost preparation method thereof. The preparation method is characterized in that a stable precursor solution is adopted to synthesize the TiO2-based electrode material with controllable composition and excellent performance by liquid-phase method or solid-phase reaction. The TiO2 can be doped with one of the transition metals selected from Zr, Hf, V, Nb, Ta, Cr, Mo, W or Sc, with a doping concentration of 0 to 30 mol%, to adjust the band structure of the TiO2 and improve the charge separation transportation capability of the TiO2, thereby improving the conversion efficiency of solar batteries. The maximal photoelectrical conversion efficiency is improved by 27.2% than that of the non-doped material.
