Abstract

Beneficial effects of polythiophen layers on ruthenium (Ru) photosensitizer in dye-sensitized solar cells (DSSCs) are observed. The thiophene is photoelectrochemically polymerized by the photoexcitation of Ru photosensitizers on TiO₂. In situ polymerization enables the formation of uniform polythiophene layers on Ru-complexes/TiO₂. The polythiophene layers have hydrophobic nature and bridge the energy level between Ru-complexes and iodine/iodide, which suppress the recombination reaction and improve the concentration of photoinjected electron in TiO₂ layers. The DSSCs with polythiophene protecting layers shows a power conversion efficiency of 6.01%, which is a 30% increase compared to one without polythiophene layers.
