Modeling and Performance Analysis of Indoor Bifacial Perovskite Photovoltaics with SCAPS‐1D

Abstract Indoor bifacial photovoltaics (i‐BPVs) have drawn a lot of interest as a possible option for efficiently absorbing light from artificial indoor light sources. Comparing other emerging PV technologies, perovskite‐based i‐BPVs (i‐BPPVs) have shown superior device performance under artificial light sources with affordable fabrication cost. Nonetheless, designing i‐BPPVs to efficiently harvest energy from indoor light sources remains both challenging and attractive research field. This study mainly focuses on the simulation of i‐BPPVs, aiming to optimize their performance under various ideal and non‐ideal conditions using SCAPS‐1D. The effects of various parameters such as series and shunt resistance, perovskite layer thickness, interfacial defects, irradiance power, and temperature are investigated under indoor light environments. Designed bifacial architecture Glass/ITO/SnO 2 /MAFAPbI 3 /Spiro‐OMeTAD/ITO have shown power conversion efficiencies (PCE) of 33.74% and 23.45%, when exposed from top‐ and bottom‐sides, respectively, employing nearly realistic operating conditions. The outcomes of this simulation study provide crucial insights into the design and development of next‐generation i‐BPPVs, opening the door to more efficient and sustainable indoor energy harvesting options.
