چکیده :

This paper mainly refers to experimental data utilization and verification, which provides to understand better PSC behavior, and not to give a detailed analysis or interpretation of the device physics. Three models have been considered for device modeling and characterization. First, ion vacancy and charge carrier transport model, which includes 1) single-layer model, 2) Ion Monger model for timescale simulation, then 3) SCAPS model, for steady-state device model verification, are exploited. Details of an experiment data verification in planar perovskite solar cell simulators in transient timescale and steady-state modeling simulation are presented. To characterize ion vacancy density, electric potential, electron concentration, and hole concentration profiles in a transient timescale, Ion Monger is capable of doing so. Also, steady-state numerical simulation of candidate structures is modeled employing the SCAPS-1D simulator. The model's validity is demonstrated in the experimental data. MoS2 and TiO2 as electron transporting layers are observed in the planar perovskite structure.
