The Investigation SnO 2 As the Electron Transport Layer (ETL) on Perovskite Solar Cells

Abstract

The present study depicts the validation between the simulation and experimental model for representing the improved performance of perovskite solar cell (PSC) by examining defect characteristics, Conduction Band Offset (CBO), the Valence Band Offset (VBO), thickness, Electron Mobility (μ e ), Absorption Coefficient Constant (α), Effective Density of the Conduction Band States (N C ), and Interface Density (N t ). With investigating interface characteristics at the Electron Transport Layer (ETL) / Perovskite and Perovskite / Hole Transport Layer (HTL), Fill Factor (FF) and open-circuit voltage (Voc) can be better determined. The SCAPS-1D software is the mean, which has been utilized to investigate the mentioned parameters and the cell Power Conversion Efficiency (PCE).
