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.

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.

  4. What is the Department of Transportation shipping information for this product?

    Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product. 

  5. What are the advantages of dye solar cells?

    Dye solar cells (DSCs) are 3rd generation solar cells with the promise of high efficiency combined with low production costs.

  6. What can cause degradation of the dye solar cell?

    Dye solar cells degrade from ultraviolet radiation.  For this reason, the barrier may include UV stabilizers and/or UV absorbing luminescent chromophores (which emit at longer wavelengths) and antioxidants to protect and improve the efficiency of the cell.

  7. What are the disadvantages of dye solar cells?

    The major disadvantage to the dye solar cell design is the use of a liquid electrolyte, which has temperature stability issues. The electrolyte can freeze at low temperatures and expand at higher temperatures.  It the electrolytes freezes, power production would cease, and it could potentially lead to physical damage.  If the liquid expands at higher temperatures, sealing the panels would be difficult.
