Title:
PHOTOELECTRIC CONVERSION ELEMENT, DYE-SENSITIZED SOLAR CELL, METAL COMPLEX DYE, DYE SOLUTION, AND TERPYRIDINE COMPOUND OR ESTERIFICATION PRODUCT THEREOF
Document Type and Number:
WIPO Patent Application WO/2016/052193
Kind Code:
A1
Abstract:
Provided are: a photoelectric conversion element that comprises a conductive support body, a photosensitive layer containing an electrolyte, a charge transfer layer containing an electrolyte, and a counter electrode, wherein the photosensitive layer comprises fine semiconductor particles having a metal complex dye that is represented by formula (I) loaded thereon; a dye-sensitized solar cell; a metal complex dye used in the photoelectric conversion element and the dye-sensitized solar cell; a dye solution; and a terpyridine compound or an esterification product thereof. Formula (I): M(LA)(LD)p(LX)q∙(CI)z. In the formula, M represents a metal ion. LA represents a tridentate ligand that is represented by formula (LA-1). LD represents a bidentate or tridentate ligand. p represents 0 or 1. LX represents a monodentate ligand. q represents 0, 1, or 3. CI represents a counterion. z represents an integer of 0-3. In formula (LA-1), Za and Zb each represent a non-metal atom group that is necessary in order to complete a 5- or 6-membered ring. At least one of the Za ring and the Zb ring comprises an acidic group. LW represents a nitrogen atom or CRW. RW represents a hydrogen atom or a substituent. L1 represents an aromatic ring group that is either a single ring selected from the group consisting of a benzene ring, a furan ring, a selenophene ring, a cyclopentadiene ring, a silole ring, and a nitrogen-containing aromatic ring or a multi-ring containing the single ring as a fused ring, and this aromatic ring group is bonded to a ring that includes LW by a carbon atom that constitutes the ring of the single ring. L2 represents an aromatic ring group. m represents an integer of 0-5. R1 and R2 each represent an alkyl group or an aromatic ring group.
