Title:
METHINE DYE AND DYE-SENSITIZED PHOTOELECTRIC CONVERSION ELEMENT
Document Type and Number:
WIPO Patent Application WO/2015/037676
Kind Code:
A1
Abstract:
The present invention pertains to the development of a dye having a specific structure, a photoelectric conversion element having high optical durability and being sensitized using the dye, and a solar cell comprising the photoelectric conversion element and being capable of maintaining high conversion efficiency. A methine dye represented by formula (1) (in formula (1), m represents an integer 1 to 5, l and n represent an integer 0 to 6, and j represents an integer 0 to 3. X1 and Y1 each independently represent a carboxyl group, a cyano group, or the like. Z1 and Z2 each independently represent an oxygen atom, a sulfur atom, or the like. A1, A2, A3, A5, and A6 each independently represent a hydrogen atom, an aromatic residue, an aliphatic hydrocarbon residue, a cyano group, or the like. A4 represents a hydrogen atom, an aliphatic hydrocarbon residue, a cyano group, or the like. A7 and A 8 each independently represent a hydrogen atom, an aliphatic hydrocarbon residue, a cyano group, or the like. R1 and R2 each independently represent a specific aromatic residue, a heterocyclic residue, or the like.)
