Triarylamine on nanocrystalline TiO2 studied in its reduced and oxidized state by photoelectron spectroscopy

Article Abstract:

An investigation on the electronic structure of electrochemically reduced and oxidized triarylamine layer absorbed on a nanocrystalline TiO2 film is presented. The purpose of the study is to gain further insight into the electronic and geometrical changes upon changing the oxidation state of the molecule at the surface.

The photon-driven hydrophilicity of titania: A model study using TiO2(110) and adsorbed trimethyl acetate

Article Abstract:

The hydrophilic nature of clean surfaces and the hydrophobic nature of TMA-covered surfaces are revealed by the behavior of H2O on clean and trimethylacetate. The TMA is removed and the wetting behavior of the surface is restored, by the irradiation with the UV light in the presence of Torr of O2.

Investigation of sensitizer adsorption and the influence of protons on current and voltage of a dye-sensitized nanocrystalline TiO2 solar cell

Article Abstract:

ATR-is used to investigate the interaction between N3, N719, and N712 stabilizers with nanocrystalline TiO2 film. In nanocrystalline TiO2 based solar cells, the performance of N3 sensitizer with different degrees of protonation were investigated.
