ABSTRACT:
A photosensitizing transition metal complex of the formula (Ia) MLY1, (Ib) MLX3(Ic) MLY2X, (Id) MLY3X or (Ie) MLY4X in which M is a transition metal selected from ruthenium, osmium, iron, rhenium and technetium, preferably ruthenium or osmium. X is a co-ligand independently selected from NCS—, Cl—, Br—, I—, CN—, H2O; pyridine unsubstituted or substituted by at least one group selected from vinyl, primary, secondary or tertiary amine, OH and C1-30alkyl, preferably NSC and CN—; L is a tridentate polypyridine ligand, carrying at least one carboxylic, phosphoric acid or a chelating group and one substituted or unsubstituted alkyl group having 1 to 50 carbon atoms, substituted or unsubstituted alkylamide group having 2 to 30 carbon atoms or substituted or unsubstituted aralkyl group having 7 to 50 carbon atoms. A dye-sensitized electrode includes a substrate having an electrically conductive surface, an oxide semiconductor film formed on the conductive surface, and the above sensitizer of formula (Ia), (Ib), (Ic), (Id) or (Ie) as specified above, supported on the film. A solar cell includes the above electrode, a counter electrode, and an electrolyte deposited there between.
