PHOTOELECTRIC CONVERSION ELEMENT, PHOTOELECTROCHEMICAL CELL, AND PIGMENT

摘要

This photoelectric conversion element is characterized in being provided with a photoreceptor layer having a pigment comprising at least a compound represented by general formula (I), and semiconductor microparticles. (In general formula (I), Q represents a benzene ring group or a naphthalene ring group, and X1 and X2 represent a sulfur atom, an oxygen atom, or C(Ra)Rb. Ra and Rb represent a hydrogen atom, an aliphatic group, an aromatic group, or a heterocyclic group bonded by a carbon atom. R and R' represent an alkyl group or an aromatic group. P1 and P2 represent a nonmetallic atom group needed to form a polymethine pigment having a specific structure. W1 is a counterion when a counterion is needed to neutralize a charge.)
