Abstract:

A thin films of transition metal chalcogenides have been electrosynthesized on indium-tin-oxide (ITO)-coated glass and stainless-steel substrates. The deposition potential for the chalcogenide thin film was first derived from cyclic voltammetry (CV) technique followed by synthesis of the chalcogenides by electrodeposition technique. In the case for transition metal chalcogenide compounds, the potential limit range -1.00 V to 1.00 V was found to be suitable for CV measurements. A three – electrode cell system was adopted for the CV measurement and electrodeposition of the films. The films were characterized for their structural, morphological and compositional characteristics. Their optical and semiconducting parameters were also analyzed in order to determine the suitability of the thin films for photoelectrochemical (PEC) / solar cell applications. Structural analysis via X-ray diffraction (XRD) analysis reveals that the films are polycrystalline in nature. Scanning electron microscope (SEM) studies reveals the films were adherent to the substrate with uniform in nature which also confirmed by Transmission electron microscope (TEM). Compositional analysis via energy dispersive X-ray (EDX) technique confirms the presence of both transition metal and chalcogenide elements in the films. The optical studies show that the films are of direct bandgap. Results on the semiconductor parameters analysis of the films showed that the nature of the Mott-Schottky plots indicates that the films obtained are of n-type material. For all films, the semiconductor parameter values come in the better range for these transition metal chalcogenides which has proven that these thin films are capable as solar / PEC cell materials in replacing the existing Si.
