STRUCTURAL, OPTICAL AND ELECTRICAL PROPERTIES OF CHEMICAL BATH DEPOSITED PBS/CDSFILMS GROWN ON DIFFERENT SUBSTRATES

PbS/CdS bilayer thin films have been grown on glass, GaSe, and InSe substrates by chemical bath deposition. Structural, morphological, optical and electrical properties have been studied by X-ray diffraction (XRD), Atomic Force Microscopy (AFM), optical absorption and I-V measurements. The PbS/CdS layers have been found to grow with cubic and hexagonal structure and showed preferred orientation in (200) and (002) planes, respectively. The particle sizes and energy bang gaps of PbS/CdS films have been shown to be substrate dependent. Particle sizes of PbS/CdS films grown on glass, GaSe and InSe substrates determined from AFM images were in the 81-301 nm range while direct band gap energies calculated from optic absorption spectra were in the 1.22-1.98 eV range.The PbS/CdS bilayers have been shown to be photosensitive through I-V measurements.
