Abstract

TiO₂ thin films were prepared on electrochemically etched porous Si by anodic oxidative hydrolysis of TiCl₃ for the purpose of solar cell application. We compared electrochemical and photoelectrochemical properties of the TiO₂-deposited porous Si electrodes (TiO₂/porous Si) with those of a porous Si electrode. The TiO₂/porous Si showed prolonged stability of photoluminescence and enhancements of photovoltage and photocurrent by 0.13 V and 67% increase, respectively, in comparison with porous Si due to the reduction of surface traps for charge carriers in the presence of TiO₂ thin layer. Li⁺ and Na⁺ ions exhibited intercalation and deintercalation through the electrodeposited TiO₂ film.
