C106 Dye is ruthenium complex dye developed for high-efficiency dye-sensitized solar cells (DSSC). Power conversion efficiencies of 11.7-12.1% have achieved in high-efficiency dye-sensitized solar cells under air-mass 1.5G simulated sunlights [1-5].

C106 Dye provides higher degree of conjugation to the ligand which in return enhances its overall optical absorption capacity. With hexyl groups enhancing its hydrophobic nature, C106 Dye not only increases electron donating property to the core of the metallic centre, but also provides steric hindrance to minimize packing and agglomeration behaviour thus higher overall device performance could be expected.
