Abstract
The absorbing layer thickness is a crucial parameter that significantly impacts the performance of perovskite solar cells (PSCs). In this study, we investigated the influence of the thickness of absorbing layer on the performance of silver-doped NaZnBr3 perovskite solar cells using the one-dimensional solar cell capacitance simulator (SCAPS-1D) software. The absorbing layer thickness was varied in the range of 0.1 to 1.3 µm. The initial solar cell after simulation gave an open-circuit voltage (Voc) of 1.174 V, short circuit current density (Jsc) of 14.012 mA/cm2, fill factor (FF) of 79.649%, and the power conversion efficiency (PCE) of 13.101%. For the optimized thickness of the perovskite layer of 1.0 µm, the following solar cell characteristics were obtained: Voc = 1.197 V, Jsc = 18.184 mA·cm–2, FF = 79.110%, and PCE = 17.215%. A 31% and 30% increase of the PCE and Jsc, respectively, was observed for the optimized device parameters as compared to the initial ones. Such finding confirms the premise for excellent photon management and enhancement of PSCs performance by selecting the thickness of absorbing layer.
