Title:
PHOTOELECTRIC TRANSDUCER AND PHOTOSENSITIZING PIGMENT FOR TRANSDUCER
Document Type and Number:
Japanese Patent JP3505425
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a photoelectric transducer of photosensitizing type consisting of solid substance having an excellent photoelectric conversion efficiency, capable of suppressing exfoliation of each electrode from an electric charge conveying layer, and accomplishing a long lifetime of cell.
SOLUTION: This photoelectric transducer is composed of a semiconductor electrode 3, a pigment 4 carried thereby and expressed by ML1L3L4L5 and/or ML22L6L7, and an electric charge conveying layer 5 including a bond with the pigment 4. In the expression for the pigment, M is either of ruthenium, osmium and iron, L1 and L2 are organic ligand unsubstituted or substituted with 1-3 carboxyl radicals, hydroxyl radicals, sulfon radicsls, or cyano radicals, and at least one of L3-L5 and also of L6-L7 is able to form a bond of M with the electric charge conveying layer by a coupling radical expressed by X-Y-, where X is either of the hydroxyl radical, thiol radical, carboxyl radical, phosphonic group, sulfonic group and amino radical, while Y is two-valent aromatic compound of C3-30 substitution or non-substitution.
