Film of fine semiconductor particles for a photoelectrochemical cell

摘要

A photoelectric conversion device having a conductive support and a photosensitive layer formed on the conductive support, said photosensitive layer being composed of a layer of dye-adsorbed, fine semiconductor particles, and a metal oxide layer formed thereon by cathodic electrodeposition. The layer of fine semiconductor particles has a roughness factor of 10 or more.
