Abstract
Iron (Fe)-doped antimony trisulphide (Sb2S3) thin films were prepared by Chemical Bath Deposition (CBD) technique at temperatures 0 degrees C, 5 degrees C and 10 degrees C for 4 h and were annealed at 500 degrees C for 2 hours under N(2)enviroment. The crystallinity and morphology of un-doped and Fe-doped Sb2S3 thin films was studied with X-Ray Diffraction (XRD) and Scanning Electron Microscope (SEM), respectively. Chemical composition as well as thickness of the thin films was determined by Rutherford Back Scattering (RBS) spectroscopy. UV-Vis spectroscopy revealed that for un-doped and Fe-doped Sb2S3 thin films the optical band gap values increase to lie within the photoactive-visible region making them suitable for solar cell applications.
