cis-Bis(isothiocyanato)bis(2,2'-bipyridyl-4,4'-dicarboxylato)ruthenium(II) is known to very efficiently photo-sensitize titanium dioxide (titania) in the visible spectrum up to a wavelength of ~750nm. This compound is commonly referred as N3 dye in the literature. It is so far one of the best pigments for Dye Solar Cells, and is considered an industry standard. The N3 dye can be coated on electrodes for improving the sensitivity of the dye sensitized solar cells (DSSCs) which can further enhance the power conversion efficiency (PCE). The N3 dye is used to prepare staining solutions in which metal-oxide semi-conductor electrodes will be immersed. The dye naturally adsorbs on the semi-conductor surface, resulting in a colored electrode bearing a sensitizing layer of dye molecules. N3 acts as a fluorescent sensitive luminescence turn-on type anion sensor in aqueous solution. Spectral Data: Absorption lambdamax: 538nm; 398nm; 314nm (epsilon/10^4 M-1cm-1). Emission lambdamax: 830nm (EtOH).
