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

Abstract

Spherical voids as light scattering centers in nanocrystalline TiO2 films were realized with polystyrene particles of diameter 400 nm, 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.
