Synthesis of PbS Thin Film by Chemical Bath Deposition Method and it’s structural-Optical Studies

In the present article, we prepared a PbS Thin film by varying its physical parameters such as temperature of the solution, deposition time and concentrations and studied its structural and optical properties. Here, the PbS thin film was prepared by chemical bath deposition route. The structural behavior such as crystallite size, orientation, lattice spacing and strain broadening was also calculated. Using XRD, the PbS thin film shows cubic structure with average crystallite size is 30.04 nm for 45 oC and 31.07 nm for 65 oC respectively. The optical properties of PbS thin film were studied using UV-Visible spectroscopy and reported its value subsequently. Such kind of thin film based on PbS compound are useful to increase the efficiency of energy conversation in solar cell areas.
