An augmented lead-free Perovskite solar cell based on FASnI3 using V2O5 as HTL

Abstract

The study involved the design and analysis of FASnI3-based perovskite solar cells to determine their power conversion efficiency (PCE) under varying AB-layer thicknesses and temperatures. Despite recent advancements, organic and inorganic lead-based perovskite solar cells have faced challenges due to health hazards and device instability, hindering commercial manufacturing progress. To address this, we explored alternative charge transport materials, such as FASnI3 cells, through numerical simulation using the 1D-SCAPS software. Our investigation focused on optimizing charge transport layers and adjusting acceptor and donor concentrations to achieve high-efficiency, lead-free PSCs. Furthermore, we evaluated the performance and impact of different parameters on simulated cell devices. Through multiple simulation iterations, we achieved the best performance of the FASnI3 PS-cell, delivering a voltage of 1.04 V, current density of 29.40 mA cm−2, and Fill factor of 85.24%, resulting in an overall PCE of 24.45%.
