The use of nanostructured materials is representing a breakthrough in many fields of applications owing to their empowered functionalities. In this framework, spongy $TiO_{2}$ layers are deposited by a novel method based on grazing-incidence reactive sputtering assisted by local oxidation. The deposited material gains 50% constant porosity in volume along its thickness (hundreds of nm) and is organized by nano- and meso-pores. The $TiO_{2}$ layer is tested as a scaffold for dye-sensitized solar cells using a standard Ru-complex (N-719) working as light harvester, showing a high infiltration capability with molecular chemisorption on the surfaces needed to guarantee a photovoltaic effect.
