Laser power density effect on the properties of Sb2S3 thin films prepared by pulsed laser assisted chemical bath deposition

Abstract

Antimony Sulfide (Sb2S3) thin films were prepared using the laser assisted chemical bath deposition technique. The precursors used in the chemical bath were antimony chloride and sodium thiosulfate, the deposit was made at room temperature on glass substrate, while it was irradiated with a wavelength of 532 nm of the pulsed Nd:YAG laser. In this work, we studied the effects of energy density (1.97 x 107 and 7.07 x 106 W/cm2) and the irradiation time (30, 45 and 60 min) during the deposition process on the structure and the optical and electrical properties of the antimony sulfide films. The structure, composition, and optical and electrical properties were analyzed by X-Ray Diffraction (XRD), Raman Spectroscopy and X-Ray Emitted Photoelectron Spectroscopy (XPS), UV-Vis spectroscopy and photoconductivity. The results showed that the laser assisted chemical deposition technique is an effective synthesis technique for obtaining thin films of antimony sulfide for optoelectronic applications or in solar cells.
