Methine dye sensitized semiconductor particle

摘要

A semiconductor particle has a surface on which a methine dye is adsorbed. The methine dye has a phosphoric group of the formula (P) as a substituent group: in which L is a single bond, -O-, -S- or -NH-; and the hydrogen atoms may be dissociated from the oxygen atoms. A photovoltaic element using the particles and a photo-electrochemical cell using the element are also disclosed.
