Abstract
Undoped and Cu-doped films exhibited hexagonal SnS2 structure with different preferred orientations. The doped films cover almost all the surface uniformly with agglomerated bigger crystallites. As prepared films were highly resistive and became conducting on doping. Both films were found to be Sn-rich and the doped films confirmed the presence of copper through EDAX analyzer. There was a considerable redshift in the absorption threshold from the bulk for Cu-doped SnS2 thin films. All the films were highly reflecting in the infrared region and the reflectivity of the films decreased with doping concentration. Conducting tin sulphide nanostructures are highly applicable in dye sensitized solar cells.
