<p>Antenna ligands for use in dye-sensitized solar cells are described. The antenna ligands consist of a bidentate or tridentate heteroaromatic metal-chelating group having at least one independently selected antenna group substituted thereon, each antenna group being an independently selected substituent of the formula -R'1-Ar' or -R'1-Ar'-R2-Ar'2, wherein: R'1 is an aliphatic group of the formula -(CH=CH)n-, where n is from 1 to 3; Ar' is an aromatic group; in some embodiments a heteroaromatic group; R'2 is a covalent bond or a C1 to C15 linear or branched, saturated or unsaturated alkyl; and Ar'2 is an aromatic group. Organometallic complexes containing such ligands and dye-sensitized solar cells containing the same are also described.</p> |
