Abstract
A platinum complex represented by the formula PtL.sup.1 /L.sup.2 or PtLX.sup.1 /LX.sup.2 wherein L.sup.1 and L each represent a ligand selected from the group consisting of 2,2'-bipyridine compounds having at least one anionic group and 1,10-phenanthroline compounds having at least one anionic group, L.sup.2 represents a dithiolate selected from those represented by the formulas (a) through (d) shown in the specification, and X.sup.1 and X.sup.2 each represent a thiolate selected from those represented by the following formulas (e) and (f) shown in the specification. A dye-sensitized electrode includes a substrate having an electrically conductive surface, an oxide semiconductor film formed on the conductive surface, and the above platinum complex supported on the film. A solar cell includes the above electrode, a counter electrode, and an electrolyte disposed therebetween.
