This paper deals with the current transport mechanism of solid state photoelectrochemical cells of ITO/Cu2O/PVC-LiClO4/graphite as well as the physical properties of a component of a device affecting its performance. The principle of operation used in the photoelectrochemical cells is presented. The device makes use of ITO films, Cu2O films, PVC-LiClO4 and graphite films as photoanode, photovoltaic material, solid electrolyte and counter electrode, respectively. The device shows rectification. The Jsc and Voc obtained at 100 mW cm-2 were 3.2 × 10-11 mA/cm2 and 0.92 V, respectively.
