Electrochemical photocells consisting of a thin film anode and a Pt cathode immersed in solution have been studied. thin films were formed on Ti, Cr, Mo, , glassy carbon, and graphite substrates by coating an aqueous mixture of , , and surfactant, subsequently sintering at 400°–500°C in air. The current‐voltage (I‐V) relations, output power efficiency, open‐circuit voltage, and short‐circuit current were measured. 7% power conversion efficiency was obtained at 20 mW/cm2 light intensity after photoetching. The monochromatic I‐V curves were analyzed.
