Interpretation of apparent activation energies for electron transport in dye-sensitized nanocrystalline solar cells
Article Abstract:
The interpretation of the apparent activation energies for electron transport in dye-sensitized nanocrystalline solar cells measured under short circuit conditions with the difference between quasi-Fermi energy and the conduction band energy is presented. The results have shown that the low apparent activation energies for electron transport measured under short circuit conditions are consistent with the multiple trapping model and would not be influenced by changes in the conduction band position.

Activation energy of electron transport in dye-sensitized TiO2solar cells
Article Abstract:
A study on various characteristics of dye-sensitized nanostructured TiO2 solar cells, such as electron transport and electron is conducted using monochromatic illumination conditions. The electron transport is found to be a thermally activated process with activation energies in the range of 0.10-0.15 eV for light intensities that varied 2 orders of magnitude.

Resonance raman scattering of a dye-sensitized solar cell: mechanism of thiocynato ligand exchange
Article Abstract:
The development of the resonance raman scattering (RRS) to study mechanisms in a sealed dye-sensitized solar cell device based on the N719 dye adsorbed on TiO2 is presented. It concluded that the amount of thiocyanato groups coordinated to the dye was found to decrease with the increased amount of the iodine added or triiodide formed in the electrolyte.
