| Abstract: |
Different synthesis protocols have been developed to control TiO 2 anatase nanoparticle packing. The diameter of TiO 2 packing aggregate varies from 13 nm to a few 100 nm. Efficiency of dye-sensitized solar cells (DSSC) fabricated with the obtained TiO 2 packing aggregate films was reported to depend on the size of the packing aggregate. It increases with the increase of the aggregate size (number of TiO 2 nanoparticles) to a maximum of 4.3% and then it decreases. This effect was discussed in terms of a balance between the incident light scatterings, adsorbing amount of dye molecules, cracks free and the efficiency of electron transfer (reduction of recombination process).
