SPECIFIC COMPOUNDS - The semiconductor fine particle is titanium oxide fine particle. Totally 10 metal complex dyes have been disclosed such as iron bi(4,5-dicarboxylpyrid-2-yl)dithiocyanate (D-10) and osmium bi(4,5-dicarboxylpyrid-2-yl)dithiocyanate (D-9).    EXAMPLE - (In grams) Potassium permanganate (3.7), was dissolved in mixed solvent of water (50 ml)/acetone (25 ml). The resulting solution was added with 4,4',5,5'-tetramethyl-2,2'-bipyridine (0.5), stirred at 80 degreesC for 3 days and thermally filtered. Concentrated hydrochloric acid was added to the resulting mixture to convert the mixture into an acidic state, to separate 0.2 g of hydrochloride of the ligand (L1) by filtration. A solution of ligand (L1) (0.2) and ruthenium chloride (0.06) in dimethyl formamide (20 ml), was added to triethyl amine (0.17). The resulting mixture was heated under nitrogen for 4 hours at 120 degreesC and subsequently added with ammonium thiocyanate (0.22). The mixture was cooled, concentrated and the residue was purified. The purified residue was neutralized to obtain metal complex dye (D-1) (0.1). The dye was found to have absorption maximum at 576 nm in methanol. An electrically conductive surface of conductive glass TCO Glass-U (RTM), was applied with 20 g/m2 of titanium oxide dispersion (formed from titanium dioxide Degussa P-25 (RTM), water, Triton X-100 (RTM) and zirconium beads). An adhesive tape was attached to electrically conductive surface of conductive glass at portions of from the edge to 3 mm as a spacer, 8 conductive glasses were arranged such that adhesive tapes form both edges. The conductive glasses were applied with titanium dioxide dispersion at once, and the glasses were air dried for a day at room temperature after peeling. The conductive glass was thermally processed at 450 degreesC for half an hour to form a titanium dioxide electrode. The electrode was cooled and sequentially immersed in methanol solution comprising dye (D-1) for 15 hours, and 4-t-butylpyridine for 15 minutes. The immersed electrode was dried to obtain a dye-sensitized titanium dioxide electrode. A photoelectric conversion device was formed using the dye-sensitized titanium dioxide electrode. The conversion device was found to have open circuit voltage of 0.8 V.
