Abstract
CZTSSe kesterite nanoparticles have been investigated for the efficient. The hydrothermal method has been used to prepare the material. The various characterization like X-ray diffraction (XRD), Raman scattering, Scanning Electron Microscopy (SEM) for (UV–Vis) ultraviolet–visible spectrophotometry and (EDS) energy-dispersive X-ray spectroscopy and of the prepared nano particles have been studied. Furthermore, numerical analysis of the synthesized material has also been investigated to optimize the performance for more characterization at the device level. For the optimization purpose, we have modelled a device structure of the hybrid buffer layer and optimized its physical parameters for the efficient. Theoretical efficiency is found to be 18.46 % for the prepared model. The results of this study show that Cu2ZnSn (S, Se)4 could be used as an absorbent layer for efficient solar cell.
