Abstract
An oxygen generating electrode includes a conductive layer; a photocatalyst layer; and a light absorption. The light-absorbing layer arranged between the conductive layer and the photocatalyst layer. The light-absorbing layer is formed of one or a plurality of perovskite-type films, and each of the films contains tin (Sn), oxygen (O), sulfur (S), and one or more elements selected from Group 1 or Group 2 of the periodic table of elements. Each of the films formed by doping S for substituting an O site is set so that a band gap takes a predetermined value in a range between 0 eV to 4 eV.
