Abstract

The present invention relates to a metal complex dye, a photoelectric conversion element and a photoelectrochemical cell. The metal complex dye has a structure defined by the following general formula (1) and has one or two acidic groups. In the general formula (1), A and C have the structure of the general formula (2), and A and C may be the same as or different from each other. B represents a linking group, and n represents an integer of 1 or more. In addition, the bond of A and B and the bond of B and C may each be divalent or more. In addition, a double bond may be contained in order to maintain the resonance structure of the compound.

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...
