A carbon doped anatase TiO2 as a promising semiconducting layer in Ru-dyes based dye-sensitized solar cells

Abstract The synthesis and characterization of two simple Ruthenium(II) complexes of the type [Ru(X^N) 2 (4,4′-dicarboxybipyridine)] + (with X C, X^N benzoquinolinate, 1 ; with X N, X^N 2-pyridyl tetrazolate, 2 ) and the exploitation of a new carbon doped anataseTiO 2 paste in dye-sensitized solar cells(DSSCs) photoanode are described. In particular, glucose (C 6 H 12 O 6 ) is used as a new chemical eco-friendly C-dopant during the doping process of anataseTiO 2 nanoparticles. The proper combination of Ru(II) sensitizers and C-doped titania can afford efficient DSSC photoanodes. All the relevant photovoltaic parameters have been determined.
