Abstract
Official abstract text for this publication.
A photoelectric-conversion-device dye comprising a ruthenium metal complex, which includes a molecule including elemental phosphorous and the molecule forms a coordinate bond at least at the phosphorous atom, and which also includes a terpyridine derivative that forms a coordinate bond and has at least one adsorbing group that exhibits adsorptivity toward a metal oxide. The adsorbing group is selected from the group consisting of a carboxylic acid group, an ester thereof, or a salt thereof; a phosphonic acid group, an ester thereof, or a salt thereof; a hydroxyl group; an alkoxy group; and a sulfonic acid group or salt thereof. The dye exhibits absorption over a wide range from the visible light region to the near-infrared region, and as a result, a photoelectric conversion film, an electrode, and a solar cell having improved photoelectric conversion efficiency are provided.
