The optimized configuration, with 0.2 µm Sb₂S₃ (shallow acceptor density: 10¹⁶ cm⁻³), 0.8 µm Sb₂Se₃ (shallow donor density: 10¹⁹ cm⁻³), achieved a power conversion efficiency (PCE) of 28.39%, V_OC of 0.97 V, J_SC of 33.32 mA/cm², and fill factor of 87.91%.

Device-level simulations identified parasitic resistances as key loss mechanisms, with series resistance reducing the fill factor by up to 15%, and low shunt resistance causing open-circuit voltage drops of 50–100 mV. Pronounced J–V hysteresis was reproduced via fixed interfacial ionic charge modelling in SCAPS-1D, with forward scan PCE of 18.36% in pristine BaZrS₃ dropping to 3.70% in the reverse scan.

The synthesized structure was identified and characterized through different characterization techniques, including X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), mapping analysis, Fourier Transform Infrared Spectroscopy (FTIR), and Ultraviolet–Visible Spectroscopy (UV–Vis).
