Interpretation of the time constants measured by kinetic techniques in nanostructed semiconductor electrodes and dye-sensitized solar cells
Article Abstract:
The study investigates the physical origin of the electron diffusion coefficient Dn and electron lifetime Tn obtained by perturbation kinetic techniques, dependent on steady-state Fermi level or on carrier concentration. However, the model suggested in ref 56 needs further studies to determine the relationship of macroscopic steady-state time constants to microscopic models

Electron transport and back reaction in nanocrystalline TiO2 films prepared by hydrothermal crystallization
Article Abstract:
Preparation of nanocrystalline low-temperature TiO2 films for dye-sensitized solar cells can be made by gas-phase hydrothermal treatment of TiO2 powder with titanium salts. Improved electron transport properties were seen in the TiO2 films which shows potential for further development of hydrothermal method.

Influence of TiO(sub2) nanoparticle size on electron diffusion and recombination in dye-sensitized TiO(sub 2) solar cells
Article Abstract:
The influences of particle size in dye-sensitized solar cells on diffusion coefficient of electrons and electron recombination lifetime were calculated. The implications of particle size to solar cell efficiency are discussed.
