The current study is focusing a lot on Zinc doping at different levels (5, 10, 15, and 20 wt%) in Cadmium sulfide thin films. These films are made using the chemical bath deposition method and are grown on glass substrates. The X-ray diffraction patterns show that the Zn-doped CdS films have a hexagonal wurtzite crystal structure. The study also looks at microstructural features like crystal size, lattice constants, microstrain, and dislocation density in the films. The surface structure of the films is examined using scanning electron microscopy. The presence of Zinc in the CdS films and their elemental composition is confirmed through energy dispersive X-ray analysis (EDAX). The negative Seebeck coefficient measured in thermoelectric power tests shows that the material behaves as an n-type semiconductor. At room temperature, the carrier concentration in the Zn-doped CdS films ranges from 4.1x1019 to 10.5x1020 cm-3, indicating that the films are degenerate semiconductors. The rise in thermal conductivity of the Zn-doped CdS films is because of the increased carrier concentration. The electronic thermal conductivity of these films slightly decreases with rising temperature due to electron-phonon scattering and defects in the thin films at higher temperatures.
