Abstract
An oxygen generation electrode includes, a conductive layer including a salt of stannic acid, the salt of stannic acid having a perovskite structure, a light absorption layer disposed on the conductive layer, and a catalyst layer disposed on the light absorption layer, the catalyst layer including an oxide having a perovskite structure and being responsible for an oxygen evolution reaction, the conductive layer being doped to degeneracy with impurities, the light absorption layer forming a Type-II heterojunction with the conductive layer, the catalyst layer being doped to degeneracy with impurities, the upper end of the valence band of the catalyst layer being higher than the upper end of the valence band of the light absorption layer.
