Abstract

A metal complex dye having a structure defined by general formula (1) and having either 1 or 2 acid groups. [In general formula (1), A and C have a structure represented by general formula (2), and can be the same as or different to one another. B represents a linking group, and n represents an integer not less than 1. The bond between A and B and the bond between B and C can each be at least bivalent. Additionally, a double bond may be included so as to maintain the resonance structure of the compound. In general formula (2), R1-R8 each independently represents a hydrogen atom, a substituent group, or the bond with B in general formula (1). Among R1-R8, those components which are bonded in the same pyrrole ring can be bonded directly or via another base, and have a cyclic structure. X represents a carbon atom or a nitrogen atom. M represents two hydrogen atoms, two metal atoms or metal oxides, or, one metal atom or metal oxide].

Description

technical field [0001] The invention relates to a metal complex pigment with high conversion efficiency and excellent durability, a photoelectric conversion element and a photoelectrochemical cell. Background technique [0002] Photoelectric conversion elements are used in various optical sensors, copiers, solar cells, and the like. Among the photoelectric conversion elements, various forms such as photoelectric conversion elements using metals, photoelectric conversion elements using semiconductors, photoelectric conversion elements using organic pigments or dyes, or combinations thereof have been put into practical use. Among them, solar cells using non-exhaustible solar energy are highly anticipated for their true practical use as inexhaustible clean energy sources that do not require fuel. Among them, research and development of silicon-based solar cells has been conducted for a long time. It is also being popularized with the policy considerations of various countries...
