Abstract
The dc conductivity and thermoelectric power of PbxCd1-xS (0 ≤ x ≤ 1) thin films were fabricated and investigated for the solar cell efficiency. The deposition parameters such as time, concentration, temperature, and pH of the solution were optimized to get superior quality thin films. The optical properties revealed that the band gap of the films decreased as the composition parameter ‘x’ increased. XRD results show the films are polycrystalline with an individual hexagonal (CdS) and cubic (PbS) structure. FESEM revealed that the films have uniform surface morphology over the entire substrate. The crystallite size measured by XRD and FESEM studies was found to be varied with composition ‘x’. EDXS shows a compositional analysis of prepared films.The four probe technique is used to estimates the electrical conductivity (σ) and thermal activation energy at room temperature. The TEP data are analyzed to calculate electron carrier density (n) and mobility (μ) of PbxCd1-xS thin films at a temperature of 45 °C to 110 °C. In the photoconduction study, it is observed that dark current rises linearly with applied voltage and photocurrent varies with applied voltage. PbxCd1-xS thin film’s PEC solar cell was characterized by determining the open-circuit voltage (Voc), short circuit current (Isc), maximum power (Pmax), fill factor (ff) and efficiency (ɳ %). The area 0.2 cm2 is selected for the sample cell and was illuminated by a 90 mW/cm2 solar radiation. From the I–V higher magnitudes fill factor 37.02% and conversion efficiency 0.10940% is obtained for composition Pb0.2Cd0.8S.
