Design and Synthesis of Ruthenium (II) Complexes and their Applications in Dye Sensitized Solar Cells (DSSCs)

Abstract:

Three thiocyanate-free ruthenium (II) sensitizers, [Ru^II(dcppy)(L1-L3)](PF₆)] where dcppy = 4, 4-dicarboxylic acid-2, 2-bipyridine, L1 = 2-(2,4-difluorophenyl)-5-(trifluoromethyl) pyridine, L2 = 2-(2,4-difluorophenyl) pyridine and L3 = 2-phenyl-5-(trifluoromethyl) pyridine were synthesized and applied for dye-sensitized solar cells (DSSCs). The structures of ruthenium complexes were characterized by ¹H, ¹³C NMR and IR spectra. The absorption was studied by UV-Vis spectroscopy and the electrochemical property was determined by cyclic voltammetry. The surface morphology of ruthenium complexes on mica was examined by atomic force microscopy. The performance of this complexes as photosensitizer in TiO₂ based dye sensitized solar cells is studied under standard AM 1.5 sunlight and by using an electrolyte.
