چکیده
|
Ruthenium(ii) complex containing cis-[ru(hcbiq)(l)(ncs),where hcbiq = 4,4′-dicarboxy-2,2′-biquinoline and l = 4,4′-di-tert-butyl-2- 2′-dipyridyl coded as sps-02,was synthesized and fully characterized. this complex showed appreciably broad absorption range. the new complex was used as photosensitizer in nanocrystalline tiodye-sensitized solar cell application. cis-[ru(hcbiq)(l)(ncs) (sps-02) achieved efficient sensitization of nanocrystalline tioover the whole visible range,extending into the near-ir region (ca. 1000 nm) with superior short-circuit photocurrent density (jsc = 9.13 ma cm-2) and conversion efficiency (η = 2.09%) compared with complex cis-[ru(hcbiq)ncs) (1) under an irradiation of full sunlight (100 mw cm-2). © 2013 surya prakash singh et al.
