Abstract
A photoelectric conversion element involving a photosensitive material layer comprising a dye represented by general formula (1) and semiconductor microparticles, wherein the dye is a compound having a C5-18 aliphatic group and represented by general formula (1). In general formula (1), Q represents a tetravalent aromatic group; X1 and X2 independently represent a sulfur atom, an oxygen atom, or a group CR1R2 (wherein R1 and R2 independently represent a hydrogen atom, an aliphatic group, an aromatic group, or a heterocyclic group which can be bound through a carbon atom contained therein); R and R' independently represent an aliphatic group, an aromatic group, or a heterocyclic group which can be bound through a carbon atom contained therein; P1 and P2 independently represent a dye residue; and W1 represents a counter ion which is required for the neutralization of an electric charge.
Description
technical field [0001] The invention relates to a photoelectric conversion element and a photoelectrochemical cell with high conversion efficiency and excellent durability, in particular to a pigment for a photoelectric conversion element and a pigment solution for a photoelectric conversion element. Background technique [0002] The photoelectric conversion element can be used in various photosensors, copiers, solar cells, and the like. In the photoelectric conversion element, various forms such as metals, semiconductors, organic pigments or pigments, or combinations of these can be used to put them into practical use. In particular, a solar cell using a non-dry solar energy source does not require fuel and can use inexhaustible clean energy, so its true practical use is highly expected. Among them, silicon-based solar cells have been researched and developed for a long time, and are continuing to be popularized and developed in consideration of the policies of various cou...
