“…For solar cell manufacturing, PbS thin film has received a lot of attention recently as one of the most important IV-VI group semiconductors [2]. It has a relatively large Bohr radius of roughly 18 nm and a narrow energy bandgap, which makes it ideal for a wide range of applications.…”

The chemical bath deposition approach was used to arrange PbS and PbS coated with Ag thin layer thin films. PbS film was deposited at room temperature using thiourea and lead chloride as precursors. After the PbS film had been deposited, it was immersed in Ag precursors for 60 minutes at 50 C to coat its surface. In this study, we looked at absorbance in the 400-1000 nm range. The direct and indirect bandgaps were estimated using the Tauc method and yielded values between 1.3 and 1.45 eV. It resulted in increasing in bandgaps after coating with of Ag layer.
