Beschreibung
Zusammenfassung:	The present invention provides a method for generating hydrogen by water splitting at a higher hydrogen generation efficiency. In the present method, used is a photoelectrochemical cell comprising a container, a liquid stored in the container, a semiconductor electrode contained in the container, and a counter electrode contained in the container. The semiconductor electrode comprises a first semiconductor layer, a light-transmissive conductor layer; and a second semiconductor layer.
