The Cd$_x$Pb$_{1–x}$S thin films with different concentrations of x from 0.2 to 0.8 were synthesized using the chemical bath deposition method. X-ray diffraction (XRD) and Williamson–Hall (W–H) plot gives the crystallite size that decreases with increased concentration. XRD, high-resolution transmission electron microscopy and selected area electron diffraction patterns of the film samples evidence the hexagonal phase structures of both CdS and PbS. Energy-dispersive X-ray confirmed the presence of Cd, Pb and S in the film samples. The transmittance of the film samples increases with the increase in concentration. Optical studies show the prominent blue shift in bandgap energy, whereas the Urbach energy decreases with the increased concentration x. The electrical conductivity of the films at room temperature is of the order of 10$^{–5}$ (${\Omega}$cm)$^{-1}$. The efficiency of the heterojunction cell structures Cd$_x$Pb$_{1–x}$S/CdTe and Cd$_x$Pb$_{1–x}$S/CdSe are calculated to be 3.37 and 2.21%, respectively.
