Modification of Physical and Chemical Properties of Titanium Dioxide (TiO2) by Ion Implantation for Dye Sensitized Solar Cells

Abstract

Nowadays, ion implantation is used as a leading technique for doping. Inspite of generating lattice distortions it is preferred over other techniques due to its large range of doses, extremely accurate dose control and low temperature process. This chapter deals with the modification of physical-chemical properties of titanium dioxide (TiO 2 ) through ion implantation method. The TiO 2 material is tested in many fields, e.g., nano-catalysts, light harvesting, magnetic data storage and Optics. Various synthesis routes have been reported for the preparation of TiO 2 nano-micro structures (particulate solids). Further, implanting these particulate solids revealed anisotropic ferromagnetism at room temperature. On the other hand, noble ion implantation opens up the horizon for fabrication of plasmonic and optical composites. Here in this chapter, TiO 2 based photoanodes have been extensively examined for dye sensitized solar cells (DSSC) with metallic and non-metallic ion implantation to realize TiO 2 with specific properties.
