Title:
PHOTOELECTRIC CONVERSION ELEMENT, DYE-SENSITIZED SOLAR CELL, METAL COMPLEX DYE, DYE SOLUTION, DYE-ADSORBED ELECTRODE, AND METHOD FOR MANUFACTURING DYE-SENSITIZED SOLAR CELL
Document Type and Number:
WIPO Patent Application WO/2014/077356
Kind Code:
A1
Abstract:
A photoelectric conversion element which comprises a conductive supporting body, a photosensitive layer containing an electrolyte, a charge transfer layer containing an electrolyte, and a counter electrode, and wherein the photosensitive layer contains fine semiconductor particles that are loaded with a metal complex dye represented by formula (I); a metal complex dye; a dye solution; a dye-adsorbed electrode; a dye-sensitized solar cell; and a method for manufacturing the dye-sensitized solar cell. M(LA)(LD)(LX)mX·(CI)mY formula (I) In formula (I), M represents a metal ion; LA represents a tridentate ligand represented by formula (AL); LD represents a bidentate or tridentate ligand wherein at least one coordinating atom is an anion; LX represents a monodentate ligand; CI represents a counter ion; mX represents 0 or 1; and mY represents an integer of 0-3. formula (AL) In formula (AL), each of rings A-C represents a nitrogen-containing aromatic hetero ring; each of Z1 and Z2 represents a carbon atom or a nitrogen atom; each of Anc1-Anc3 represents an acidic group; each of X1 and X3 represents a single bond or a linking group; X2 represents a linking group that is linked in a conjugated form or a single bond, and in cases where X2 is a linking group, the linking group contains an ethenylene group, an ethynylene group, an arylene group or a heteroarylene group in a linking chain; each of R1-R3 represents a substituent; each of l1 and l3 represents an integer of 1-4; l2 represents an integer of 1-5; each of m1 and m3 represents an integer of 0-4; m2 represents an integer of 1-3; each of n1 and n2 represents an integer of 0-3; and n3 represents an integer of 0-4. In cases where X2 is a single bond, m1 or m3 represents an integer of 1-4 and X1 or X3 represents a linking group.
