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

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/SnO₂/MAFAPbI₃/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.
