The radial free-standing TiO2 nanowires were rooted into TiO2 nanoparticles film coated Ti wire via a facile hydrothermal method. This TiO2 nanowires-modified nanoparticles bilayer film acted as a multifunctional role for enhancing solar cells efficiency: light trapping, modification of thin film surface cracks, electricity-generation properties and providing fast electron transfer pathway. The study results revealed that the three-dimensional (3D) dye-sensitized solar cells fabricated with TiO2 bilayer film increased by 32.7% in the max output power as compared to the TiO2 NPs film under AM1.5G condition. This increase is mainly attributed to the better light scattering of the TiO2 bilayer film.
