Article: Analysis of graphene perovskite solar cells using SCAPS-1D Journal: International Journal of Power and Energy Conversion (IJPEC) 2026 Vol.17 No.2 pp.137 - 155 Abstract: In this study, we introduce a solar cell reconstruction using copper-graphene-perovskite sulphur as active materials, harnessing the exceptional properties of graphene. Through meticulous analysis with the solar cell capacitance simulator (SCAPS-1D), we explored the influence of the perovskite layer's thickness on overall performance. Optimising the layer at 0.7 μm thickness and a 1.5 eV band gap yielded remarkable efficiency at 20.75%. The optimised cell displayed a fill factor (FF) of 85.77%, short-circuit current density (Jsc) of 28.35 mA/cm-2, and open-circuit voltage (Voc) of 0.90 V. These findings highlight the significance of CZTSSe as a vital p-type semiconductor, advancing solar energy through perovskite absorbers. This research represents a pivotal step towards efficient and sustainable solar cell technology, offering a promising pathway to a greener, more energy-efficient future.

Optimising the layer at 0.7 μm thickness and a 1.5 eV band gap yielded remarkable efficiency at 20.75%. The optimised cell displayed a fill factor (FF) of 85.77%, short-circuit current density (J_sc) of 28.35 mA/cm^-2, and open-circuit voltage (V_oc) of 0.90 V. These findings highlight the significance of CZTSSe as a vital p-type semiconductor, advancing solar energy through perovskite absorbers. This research represents a pivotal step towards efficient and sustainable solar cell technology, offering a promising pathway to a greener, more energy-efficient future.
