Abstract :
Different synthesis protocols have been developed to control TiO2 anatase nanoparticle aggregation and cracks formation within the film formed by this nanoparticle. The diameter of TiO2 packing aggregate varies from 13nm to 100nm. Efficiency of dye-sensitized solar cells (DSSC) fabricated with the obtained TiO2 packing aggregate films was reported to depend on the size of the packing aggregate and cracks formation. This effect was discussed in terms of a balance between adsorbing amount of dye molecules, cracks free and the efficiency of electron transfer.
