Preparation of chemically deposited thin films of CdS/PbS solar cell
چکیده انگلیسی

The present paper reports the preparation of a solar cell which has a cross-sectional scheme: ITO/CdS/PbS, containing a commercially transparent conductive ITO; chemically deposited n-type CdS (340 nm) and absorbed layer of p-type PbS (1400 nm). The structural and optical properties of the constituent films are presented. X-ray diffraction showed that all of the thin films are polycrystalline. Using scanning electron microscopy, the present study revealed that the films have uniform surface morphology over the substrate. The solar cell was characterized by determining the open circuit voltage, short-circuit current density, and J–V under 40 mW/cm2 solar radiation. The efficiency of the solar cells was 1.35%, which is much higher (0.041, 0.5 and 0.1–0.4%) and slightly smaller (1.65%) than some solar cells reported in the literature.


► PbS nanocrystals was synthesized using the chemical bath deposition method.
► CdS was synthesized using the microwave-assisted chemical bath deposition.
► XRD revealed that all films were polycrystalline.
► All films have uniform surface morphology over the substrate and are of good quality.
► Solar cell conversion efficiency is more promising compared with other solar cells.
