Spatial electron distribution and its origin in the nanoporous TiO(sub 2) network of a dye solar cell
Article Abstract:
Dye solar cells were investigated by charge carrier extraction under short and open circuit conditions and an illumination intensity. A theoretical model was developed to describe the charge transport in the nanoporous TiO(sub 2) network of a dye solar cell, and the spatial distribution of the electron concentration was calculated and these results were compared with experimental data of charge carriers stored in the TiO(sub 2) network under short and open circuit conditions.

Low temperature kinetics and energetics of the electron and hole traps in irradiated Ti[O.sub.2] nanoparticles as revealed by EPR spectroscopy
Article Abstract:
The dynamics of photogenerated charge carriers trapping in deep traps and trapped electron-hole recombination in UV irradiated anatase Ti[O.sub.2] powders by electron paramagnetic resonance (EPR) spectroscopy at 10K are investigated. The results reveal that the strategy of using low temperatures contributes to the stabilization of the charged pair states for hours by reducing the rate of electron-hole recombination processes.

Conductive-matrix-mediated alkaline Fe(III/VI) charge transfer: Three-electron storage reversible super-iron thin film cathodes
Article Abstract:
An extended conductive matrix, which facilitates a 100-fold enhancement in charge storage for reversible Fe(III/VI) super-iron thin films, is presented. It is observed that Fe(VI) salts exhibit higher cathodic capacity and environment advantages, and the films are relevance toward the next generation charge storage chemistry for reversible cathodes.
