DOCUMENT TYPE: Journal CA Section: 52 (Electrochemical, Radiational, and Thermal Energy Technology) Section cross-reference(s): 29, 73, 76 A novel ligand 4,4'-bis(carboxyvinyl)-2,2'-bipyridine (L) and its ruthenium(II) complex [Ru(II)L2(NCS)2] (K8) were synthesized and characterized by anal., spectroscopic, and electrochem. techniques. The performance of the K8 complex as a charge transfer photosensitizer in nanocryst. TiO2 based solar cells was studied. When the K8 complex anchored onto a nanocryst. TiO2 film, the authors achieved very efficient sensitization yielding 77 ± 5% incident photon-to-current efficiencies (IPCE) in the visible region using an electrolyte consisting of 0.6 M Me-N-Bu imidazolium iodide, 0.05M iodine, 0.05M LiI, and 0.5M 4-tert-butylpyridine in a 50/50 (vol./vol.) mixt. of valeronitrile and acetonitrile. Under std. AM 1.5 sunlight, the complex K8 gave a short circuit photocurrent d. of 18 ± 0.5 mA/cm2, and the open circuit voltage was 640 ± 50 mV with fill factor of 0.75 ± 0.05, corresponding to an overall conversion efficiency of 8.64 ± 0.5%. .
