Abstract

The present paper describes electrochemical characteristics of photo-electrochemical cell during light-on and light-off regimes. The cell involves TiO2 as photo-anode and Pt as cathode both immersed in a aqueous electrolyte. The photo-voltage was determined for two different cell structures both equipped with TiO2 as photo-anode. The first cell involved a homogeneous electrolyte system, formed of Na2SO4, and photo-anode made of pressed polycrystalline TiO2. The second cell involved an electrolyte of different pH at both electrodes (ΔpH=14.6) and TiO2 thin film (deposited in Ti) as photo-anode. Maximum photo-voltage of these cells was 0.7 V and 1.3 V, respectively.
