Methods for forming aggregates of nanomaterials are provided. The aggregates are formed from a liquid dispersion of the nanomaterials in a liquid. The dispersion is aerosolized and the liquid removed from the aerosolized dispersion to provide the aggregates. The aggregates are useful as a photoelectric layer and/or a light-dispersive layer in dye-sensitized solar cells.
