Abstract
A photochemical electrode includes: an optical absorption layer; a catalyst layer for oxygen evolution reaction over the optical absorption layer; and a conducting layer over the catalyst layer. A valance band maximum of the catalyst layer is higher than a valance band maximum of the optical absorption layer. A work function of the conducting layer is larger than a work function of the catalyst layer.
