ORGANIC DYE, DYE-SENSITIZED METAL OXIDE SEMICONDUCTOR ELECTRODE AND DYE-SENSITIZED SOLAR CELL

An object of the present invention is to provide a dye sensitizer for a solar cell having stability and an excellent conversion efficiency. There is provided a dye sensitizer represented by the following general formula, to which a donor site (D) and an acceptor site (A) are bound via linkers (L1)n and (L2)n: (φ is an aromatic ring with or without heteroatom(s); D is a triphenylamine derivative, a carbazole derivative, a coumarine derivative or an indoline derivative; A is an organic residue having an acidic group; each of L1 and L2 is an optionally substituted divalent alkenyl group, aromatic group or heterocyclic group, and n represents an integer of 0 to 3).
