Abstract:
The Cu2Zn1-xCdxSnS4 quinternary alloy nanofibres with different Cd concentrations were grown on glass substrate using the electrospinning technique. The structural properties of Cu2Zn1-xCdxSnS4 quinternary alloy nanofibres were investigated by X-ray Diffraction (XRD), Field Emission-Scanning Electron Microscopy (FE-SEM) and Atomic Force Microscopy (AFM). Optical properties were analysed through UV-visible Spectrophotometry (UV-Vis) and Photoluminescence Spectroscopy (PL), which revealed that there is a decrease in band gap from 1.75 eV to 1.61 eV, with the increasing Cd concentration from x = 0 to x =1. The current–voltage measurements exhibited a power conversion efficiency of 3% under the solar illumination with intensity of 100 mW/cm2. Electrical properties supported that the Cu2Zn1-xCdxSnS4 quinternary alloy can be used as an absorber in solar cells. The bulk modulus, refractive index and dielectric constant, were also investigated.
