Abstract

Hollow TiO₂nanoparticles having ∼200 nm size are successfully prepared via selective etching of Au@TiO₂core shell nanoparticles which were synthesized by microwave hydrothermal growth. Electrophoretic deposition was successfully applied to make hollow TiO₂nanoparticles scattering layer for dye-sensitized solar cells (DSSCs) applications. The surface morphology and roughness features of deposited hollow TiO₂nanoparticles films are studied by field emission scanning electron microscope and atomic force microscope techniques respectively. The light scattering property of H–TiO₂makes it a promising candidate for use as the scattering layer in dye sensitized solar cells. Enhanced J_SCvalues for the H–TiO₂based DSSCs were attributed to larger dye adsorption and stronger light scattering compared to the commercial TiO₂nanoparticle with a crystalline size of 20 nm.
