The performance of Ru(II) dye-sensitized nanocrystalline TiO2 solar cells (DSSCs) is described with newly synthesized multivalent macromolecules, containing excellent optoelectronic acridinedione linked with 1,2,3-triazole units, via a novel and convenient Cu(I)-catalyzed alkyne and azide 1,3-dipolar cycloaddition (CuAAC) reaction. These unique macromolecules have proved to be highly suitable for utilizing additives in Iâ/I3â redox couple electrolytes. Among the various substitutions, the maximum photo-current conversion efficiency of about 6.4% with a Voc of 810 mV was obtained with electron rich substitutions in the nitrogen heteroatom.
