用于染料敏化太阳能电池 (DSC) 的高性能钌基染料。N-719 是对会导致电池电压升高的 N-3 染料改性得来的 High-performance ruthenium-based dye used in dye-sensitized solar cells (DSCs). N-719 is a modification of the N-3 dye which can result in increased cell voltage. Product description： Di-tetrabutylammonium cis-bis(isothiocyanato)bis(2,2′-bipyridyl-4,4′-dicarboxylato)ruthenium(II) (N-719 dye) is a ruthenium based polypyridyl mixture used as a photosensitizer. It acts as a medium for effective absorption of photons and transfer of electrons within the electrolytic solar cells. Application： N-719 dye is widely used as a sensitizer that can be coated on indium tin oxide (ITO) substrates by doctor blade technique, with different photoanode materials like titanium oxide (TiO2), zinc oxide (ZnO), and gold nanourchin for dye sensitized solar cell (DSSC) applications.
