Abstract

A novel incorporation of polyoxometalate (POM) into Cu₂O photocathodes was achieved by electrostatic adsorption of polyoxometalate on Cu₂O crystal faces, so that the Cu₂O/POM composite films exhibit significant photovoltaic enhancement because the POM could act as electron-acceptor to retard the electron–hole recombination and facilitate the photoexcited electron transfer.
