Scattering spherical voids in nanocrystalline TiO2 - Enhancement of efficiency in dye-sensitized solar cells

Spherical voids as light scattering centers in nanocrystalline TiO2 films were realized with polystyrene particles of diameter 400 run, thus enhancing the photovoltaic performance by 25% on large areas, as well as providing an indication that these films can be used with electrolytes of higher viscosity.
