Dye-sensitized nanocrystalline titanium-oxide-based solar cells prepared by sputtering: Influence of the substrate temperature during deposition
Article Abstract:
Nanocrystalline titanium oxide-based solar cells are prepared by DC magnetron sputtering onto SnO2:F-coated glass substrates kept at temperatures in the 50 < taus < 300 degree C range. Optimized deposition conditions yielded a material with parallel penniform structure and the luminous transmittance was 42%. The crystalline size was substantially enlarged at taus > 250 degree C.

Dye-sensitized solar cells based on nanocrystalline TiO2 films surface treated with Al(super 3+) ions: Photovoltage and electron transport studies
Article Abstract:
The efficiency optimization and opto-electrical characterization of dye-sensitized solar cells based on TiO2 coated with aluminum oxide is presented. It is demonstrated that the amount of aluminum oxide affects the energetics and the kinetics of the dye-sensitized solar cells and thereby its power conversion efficiency.

Diffusion impedance and space charge capacitance in the nanoporous dye-sensitized electrochemical solar cell
Article Abstract:
A simple analytical model is presented for the impedance behavior of the dye-sensitized solar cell (DSC) under forward bias revealing its nature as diffusion effect. The prediction of this model shows good qualitative agreement with the experimental results.
