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 (VOC, JSC, 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.
