dc.description.abstract | Thin TiO 2 (anatase) films were prepared by reactive DC magnetron sputtering and characterized in detail.
Specifically, they were tested as comp act blockin g underlayers in dye-sensitized solar cells. Elastic recoil
detection analysis and optical measurement showed some porosity in the sputtered films, but electrochemical
measure ments demonstrated good blocking characteristics. This suggests the presence of small
voids rather than pinholes in the deposited films. In the case of an iodide/iodine redox couple, thin underlayers
(20 nm) improved the fill factor without affecting other properties of the cell. In case of a
ferrocene/ferrocenium-based electrolyte, the presence of underlayers was necessar y to obtain functional
