The role of active and conductive layer thickness in maximizing power conversion efficiency of perovskite solar cells

Abstract

This study investigates the effect of active and conductive layer thickness on photovoltaic performance in perovskite solar cells, addressing the need for efficient and sustainable energy solutions in light of current environmental challenges. Using OghmaNano software, we analyzed how variations in thickness of the perovskite, fluorine-doped tin oxide (FTO), and gold (Au) layers influence key performance metrics, including power conversion efficiency (PCE), fill factor (FF), open-circuit voltage (Voc), and short-circuit current density (Jsc). The ideal thicknesses identified for achieving maximum PCE are 775 nm for the perovskite layer, 50 nm for the FTO layer, and 100 nm for the Au layer. This study underscores the complex relationship between light absorption and charge transport in perovskite solar cells and highlights the importance of fine-tuning layer thickness for enhanced efficiency. The simulation-based approach used here proves valuable for its practical efficiency, reducing both time and cost compared to experimental fabrication.
