Title:
SEMICONDUCTOR PHOTOELECTRODE, METHOD FOR MANUFACTURING SUCH SEMICONDUCTOR PHOTOELECTRODE AND LIGHT ENERGY CONVERTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2006/114972
Kind Code:
A1
Abstract:
A semiconductor photoelectrode is provided with a metal substrate having an uneven surface, and a semiconductor layer which is formed on a surface of the metal substrate and composed of a material having photocatalytic characteristics. Thus, light absorption efficiency is improved, and furthermore, charge recombination can be prevented.
