Electron injection and recombination in dye sensitized nanocrystalline titanium dioxide films: a comparison of ruthenium bipyridyl and porphyrin sensitizer dyes
Article Abstract:
A comparison is conducted between the recombination and the electron injection kinetics of two porphyrin sensitizer dyes and a ruthenium bipyridyl. The study allows for the direct investigation of the link between dye photophysics/redox potential and interfacial electron transfer kinetics.

Modulation of the rate of electron injection in dye-sensitized nanocrystalline TiO2 films by externally applied bias
Article Abstract:
The influence of applied electrical potential and the presence of potential determining ions in the electrolyte upon the kinetics of electron injection in RuL2(NCS)(sub 2)- sensitized nanocrystalline TiO2 films are studied. The result indicates that the retardation of the injection kinetics in the absence of potential determining ions is attributed to the influence of these ions upon the electronic density of states of the TiO2 electrode.
