“…However, these models are still under dispute in the literature [91,92], and the process of synthesis of sulfides requires further studies. Cathodic electrodeposition of thin films of various metal oxides is also possible [64,78].…”

“…In the literature, the electrodepositions of CdS thin films have been carried out from acidic and aqueous solutions using 2-electrode and 3-electrode systems. In these reports different sulphur precursors such as sodium thiosulphate (Na 2 S 2 O 3 ) [13][14][15][16], ammonium thiosulphate (NH 4 ) 2 S 2 O 3 [17] and thioacetamide (C 2 H 5 NS) [18] have been used. The CdS thin films grown by these precursors were polycrystalline, homogeneous, transparent and showed good adhesion to the underlying transparent conduction oxide (TCO) substrates.…”

CdS thin films have been successfully electrodeposited on glass/FTO substrates using acidic and aqueous solution of CdCl 2 .xH 2 O and thiourea (SC(NH 2) 2). The electrodeposition of CdS thin films were carried out potentiostatically using a 2-electrode system. The prepared films were characterised using X-ray diffraction (XRD), Raman spectroscopy, Scanning electron microscopy (SEM), Atomic force microscopy (AFM), Photoelectrochemical (PEC) cell measurements, Electrical resistivity measurements and UV-Vis spectrophotometry to study their structural, compositional, morphological, electrical and optical properties, respectively. The structural studies show that the asdeposited and annealed CdS layers are polycrystalline with hexagonal crystal structure and preferentially oriented along (200) planes. The optical studies indicate that the ED-CdS layers have direct bandgaps in the range (2.53-2.58) eV for the as-deposited and (2.42-2.48) eV after annealing at 400 o C for 20 minutes in air. The morphological studies show the good coverage of the FTO surface by the CdS grains. The average grain sizes for the as-deposited and annealed layers were in the range (60-225) nm. These grains or clusters are made out of smaller nano crystallites with the sizes in the range ~(11-33) nm. The electrical resistivity shows reduction as thickness increases. The resistivity values for the asdeposited and annealed layers were in the range (0.82-4.92)×10 5 Ωcm. The optimum growth voltage for the CdS thin films was found to be at the cathodic potential of 797 mV with respect to the graphite anode. No visible precipitations of elemental S or CdS particles were observed in the deposition electrolyte showing a stable bath using thiourea during the growth.

“…CdS has a direct band gap (E g ) of 2.42 eV at room temperature and a high optical absorption coefficient on the order of 4 Â 10 4 cm À1 at energies above the E g (Ekuma et al, 2011;Zarebska and Skompska, 2011), resulting in wide application of CdS in modern photoelectronic devices such as solar cells, optical detectors, piezoelectric transducers, light emitting diodes, and transparent UV protection devices. For example, CdS thin films are highly favorable in heterojunction thin-film solar cell applications because of their excellent optical E g , photoconductivity, and high electron affinity (Ferekides and Britt, 1994).…”
