- Abstract
- Novel ruthenium bipyridyl sensitizer incorporating conjugated benzo[1,9]quinolizino-(acridin-2-yl)vinyl-2,2??-bipyridine ligand [JJ-12] has been synthesized and demonstrated as efficient sensitizer in dye-sensitized solar cells. A mesoporous titania film stained with JJ-12 exhibits a remarkable incident monochromatic photon-to-current conversion efficiency of 82. Under standard AM 1.5 sunlight, the solar cell using a liquid-based electrolyte consisting of 0.6M 1,2-dimethyl-3-propylimidazolium iodide (DMPII), 0.05MI2, 0.1MLiI, and 0.5M tert-butylpyridine in acetonitrile exhibits a short-circuit photocurrent density of 16.47mA/cm2, an open-circuit voltage of 0.71V, and a fill factor of 0.71, corresponding to an overall conversion efficiency of 8.34. © 2012 Jeum-Jong Kim et al.
