Abstract:
Thin films of cadmium sulfide (CdS) with different film thicknesses
were chemo-synthesized onto soda lime glass and fluorine doped tin oxide (FTO) coated glass substrates. The synthesized CdS films were
characterized by using UV-vis spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM) and atomic force microscopy
(AFM). The XRD patterns revealed the formation of CdS with a cubic crystal structure. The variation in band gap energies was found to be
in the range of 2.42–2.85 eV. An increase of 0.43 eV over the bulk band gap energy of CdS was found due
to the quantum size effect in CdS thin films. The atomic force microscopy study depicted a novel egg-like morphology of CdS
nanoparticles. Further, photoelectrochemical (PEC) performance of as grown CdS thin films was investigated using two electrode
configurations in polysulfide electrolyte. The sample with film thickness 1389 Å showed the best PEC performance
compared to other samples.
