Title
(EN) A PHOTOELECTRODE AND METHOD FOR FABRICATION THEREOF
(FR) PHOTOÉLECTRODE ET SON PROCÉDÉ DE FABRICATION
Abstract
(EN) A photoelectrode including a substrate including a semiconductor, the substrate having a light receiving side and a back side that is opposite to the light receiving side; a thin metal layer on the back side of the substrate; and a catalyst disposed on the outer surface of the thin metal layer.
(FR) Photoélectrode comprend un substrat comprenant un semi-conducteur, le substrat ayant un côté de réception de lumière et un côté arrière qui est opposé au côté de réception de lumière; une couche mince de métal sur le côté arrière du substrat; et un catalyseur disposé sur la surface extérieure de la couche mince de métal.
