Abstract

Cu2O films as a photocathode for photoelectrochemical water splitting were potentiostatically deposited on FTO glasses. The morphology and composition of the electrodeposited Cu2O films were adjusted by the applied potentials. The potential-dependent grain size of Cu2O films was characterized by XRD and SEM analysis. Photoelectrochemical properties of the fabricated Cu2O photocathodes were investigated with photocurrents as a function of potentials under 1 sun condition of 100mW/㎠. Photocurrents of the electrodeposited Cu2O films were controlled with the tailored surface morphologies of Cu2O photocathodes.
