A terrylene chromophore exhibiting a high extinction coefficient has been developed as a sensitizer for photovoltaic applications. The photophysical and photochemical properties of the dye were analyzed both experimentally and theoretically. Terrylene-sensitized nanocrystalline TiO 2 solar cells yielded good photocurrents providing more than 60% in external quantum efficiency. The photoinduced...
In this work, photoelectron spectroscopy is used to measure the electronic density of states in the band gap region of a nanostructured TiO 2 film. Such nanostructured films are used in dye-sensitized solar cells, and in this study a plain TiO 2 film as well as a dye-sensitized film were examined. Further, to simulate the electrolyte effect on the energy levels at the oxide/dye/electrolyte...
