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.

Ruthenium-Based Dyes for Dye Solar Cells

Dye solar cells (DSCs) are third generation solar cells with the promise of high efficiency combined with low production costs. While present day DSCs provide light-to-electricity conversion of up to 11%, significant further improvement is envisaged through optimized materials and novel cell and module architectures.

Organic Dyes for Efficient and Stable Dye-Sensitized Solar Cells

Over the last decade, dye-sensitized solar cells (DSSCs) have attracted much attention because these unconventional solar cells exhibit high performance and have the potential for low-cost production.

Synthesis of ZnO Aggregates and Their Application in Dye-Sensitized Solar Cells

One of the more traditional photovoltaic devices, single crystalline silicon solar cells were invented more than 50 years ago, currently make up 94% of the market. Single crystalline silicon solar cells operate on the principle of p-n junctions formed by joining p-type and n-type semiconductors.
