Efficacy analysis of BaZrS₃-based perovskite solar cells: investigated through a numerical simulation

ABSTRACT

Performance optimisation of perovskite-based solar cells is considered as one of the most important scientific challenges in photovoltaic technologies. In order to address this challenge, SCAPS-1D software was employed to evaluate the potential of BaZrS₃ material as an absorbent layer for optimal performance of PSCs (Perovskite Solar Cells). The device structure that we proposed is: (front contact) FTO/(ETL) TiO₂/ (absorber) BaZrS₃/(HTL) Spiro-OMeTAD/(Metal Back Contact) Au. The optimised parameters (defect density, doping concentration, and thickness) of each layer of the device structure were determined and discussed. Further, the performance parameters (V_OC, J_SC, FF, and PCE) of the optimised device structure were found to be 1.08 V, 16.80 mA/cm², 88.60%, and 16.07%, respectively at room temperature. Besides, it was found that when the temperature rises from 300K to 440K, a 1.5% high in PCE is observed, indicating the thermal stability of the BaZrS₃ perovskite light absorber.
