Abstract

This work comprises an experimental study on the effect of various dispersing agents on the morphology of mesoporous TiO2 films prepared by the doctor blade method and on the performance of the resulting dye-sensitized solar cells. TiO2 films were prepared using a commercial nanopowder, Degussa P25, which was ground in a mortar, with different dispersing agents and under continuous grinding, in order to break the large agglomerates (>1 μm), present in the powder. These additives can be different acids or bases and must prevent also re-agglomeration of the nanoparticles, by forming a surface charge.
