What is N719?

Description

Di-tetrabutylammonium cis-bis(isothiocyanato)bis(2,2′-bipyridyl-4,4′-dicarboxylato)ruthenium(II), N719 dye, is the ammonium salt of N3 dye.?With changes to increase cell voltage and solubility in polar solvents comparing with N3 dye, N719 dye is also one of the most common high performance dyes that are developed for DSSC solar cells.

The Uses of N719

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.

General 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.
