Numerical investigation of Cs2AgBiBr6 double perovskite solar cell with optimized performances

Double perovskite solar cells (DPSCs) are environment-friendly materials used for the efficient conversion of solar energy to electrical energy for tremendous growth in the development of the photovoltaic community. In the present manuscript, SCAPS-1D software is used for the study of Cs2AgBiBr6 absorber-based double perovskite solar cells with SnO2 and MoO3 as ETL and HTL respectively. Parameters such as short circuit current density, fill factor, open circuit voltage, power conversion efficiency, and quantum efficiency have been analyzed under the working temperature, absorber thickness, metal work function, and defect concentration. After the optimization of the device, the electrical parameters of perovskite solar cells such as PCE 11.41 %, Jsc 9.4741 mAcm−2, FF 72.61 %, and Voc 1.419 V were achieved. This configuration allows the researcher to characterize basic solar cell features to achieve high photovoltaic device outcomes.
