Surfactant free most probable TiO2 nanostructures via hydrothermal and its dye sensitized solar cell properties

Tailoring the nano-morphology and nano-architecture of titanium dioxide (TiO 2 ) is the most important task in the third generation solar cells (Dye sensitized solar cells/Quantum dot sensitized solar cells) (DSSCs/QDSSCs). In this article we present complete study of surfactant free synthesis of TiO 2 nanostructures by a simple and promising hydrothermal route. The plethora of nanostructures like nanoparticles clusters, 1D tetragonal nanorods, 3D dendrites containing nanorods having
