K19 Dye

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.]

Application	Electron transfer from K-19 dye to the conduction band of Titania is completed within 20 fs while charge recombination has a half-life of 800 μs. The high extinction coefficient of this sensitizer enable realization of a new generation thin-film dye-sensitized solar cells (DSCs) yielding high conversion efficiency at full sunlight, even with viscous electrolytes based on ionic liqs. or nonvolatile solvents, making solar cell devices exhibit excellent stability under light soaking.
