[Description]

Cis-bis(thiocyanato)(2,2'-bipyridyl-4,4'-dicarboxylic acid)(4,4'-bis(phexyloxystyryl)-2,2'-bipyridine)ruthenium(II), K19 Dye sensitizer, is ruthenium complex dye developed for high-efficiency dye-sensitized solar cells (DSSC).?High extinction coefficient (18200 M-1cm-1) of K19 sensitizer enables realisation of a new generation thin-film dye-sensitized solar cells (DSCs) yielding higher conversion efficiency [1, 2].
[Uses]

K19 Dye is an organo-metallic dye that can be used as a photosensitizing material in the fabrication of dye sensitized solar cells (DSSCs). It shows a short circuit photocurrent density of 15.1 mA/cm2, an open circuit voltage of 747 mV and a fill factor of 0.69.
[General Description]

K19 Dye is an amphiphilic ruthenium sensitizer with a good molar extinction coefficient, which remains stable under thermal stress and light soaking. It can be synthesized by forming a reaction mixture of 4,4′-Bis(p-hexyloxystyryl)-2,2′-bipyridine, dichloro(p-cymene)ruthenium(II) dimer, and 4,4′-dicarboxylic acid-2,2′-bipyridine. It shows an overall power conversion efficiency (PCE) of 11% and can be used as an active material in electrochemical applications.
