Abstract Mesoporous TiO2 thin film has been considered as a benchmark material in the applications of dye sensitised solar cells DSSCs due to a combination of the physical properties that are inherent to the metal oxide and its particular structuring, in addition to its chemical stability and commercial availability.

Branched Nanostructured Anodes For Dye-Sensitized Solar Cells
For p-type DSSCs, we computed the hole injection and recombination rate at the semiconductor-dye NiO-C interface based on theories applied previously for electron injection and recombination in n-type DSSCs, derived from Fermi golden rule and non-adiabatic charge transfer theory. Our analysis showed that the faster recombination in p-type in comparison to n-type was due to difference in Franck-Condon factor of the relevant transitions. For n-type DSSCs, we devised a statistical model based on the electronic structural properties of dyes for predicting the efficiency of this device with confidence when a new dye was employed.
The approach for constructing the model was QSAR-like and involved examining correlations between the efficiency of the device and a number of predictors that were properties of the dye. For photo-catalytic reduction of carbon dioxide to produce methane, we studied with DFT calculations three competing reaction mechanisms on TiO2 anatase proposed in literature on the basis of experimentally observed reaction intermediates.
By comparing the thermodynamics of mechanisms we showed that the formaldehyde pathway was the most favorable reaction mechanism. The computational methodology employed was useful for testing mechanistic hypotheses for reactions on the surface of solid catalysts.
