Functional Polymers: Ruthenium complexes incorporated into conjugated polymers for Dye-Sensitized Solar Cells

The synthesis of two ruthenium terpyridine complexes containing conjugated polymers is reported and their application as photosensitizers in dye-sensitized solar cells (DSSC) based on TiO2 nanoparticles and nanotubes was studied. The polymers were synthesized by the palladium-catalyzed coupling reaction between the ruthenium complex monomer and the fluorene-based comonomer. Functionalization with a carboxylic acid group strongly facilitated the anchorage of polymer dye molecules on the electrode surface. The power conversion efficiencies of the DSSCs sensitized with polymers functionalized with carboxylic groups were in the range between 0.12 and 0.13%. It was found that DSSCs fabricated from TiO2 nanoparticles and nanotubes substrates showed comparable performance.
