“…During the past several years, the rapid progress of Perovskite Solar Cells (PSCs) have drawn significant attention in solar cell research, displaying promising advancements in both cost-effectiveness and efficiency. Introduced by Lev Perovskite in 2009, the initial PSC exhibited a modest efficiency of 3.8% 1 , 2 . However, within a decade, PSC efficiency skyrocketed to a remarkable 23.7% for Methyl Ammonium Lead Halide (CH 3 NH 3 PbI 3 ) perovskite-based cells 3 .…”

“…To achieve the maximum power conversion efficiency, both layers are essential and require immaculate layers with low bulk and interface defects. The quest for improved stability and performance in perovskite solar cells emphasizes the importance it is to switch from conventional or tandem structures to a bifacial structure, particularly for applications such as Vehicle Integrated Photovoltaics (VIPV) and Building Integrated Photovoltaics (BIPV) 2 . This paper advocates the development of stable and effective bifacial solar cells designed to be cost-effective, with potential scalability in manufacturing techniques, as depicted in Fig.…”

The most rapidly expanding type of solar cells are the Perovskite Solar Cells (PSCs), because of its high device performance, ease of synthesis, high open-circuit voltage, and affordability. Despite these advantages, the development of perovskite-based solar cells continues to be impeded by the issues with perovskite stability and the utilization of the hazardous heavy element lead (Pb). The study emphasizes on the bifacial structure that maintains the conventional absorber layer and electron transport layer (ETL) in the optimized PSC structure. This study employs SCAPS software for device simulation to comprehensively analyze how various parameters affect the performance of solar cells. Additionally, doping concentration variation in both ETL and HTL are explored. The simulation reveals that changing device structure from monofacial to bifacial significantly influences PSC performance, demonstrating that optimizing individual layers effectively enhances overall solar cell performance. The optimized structure achieves impressive PSC performance metrics through parametric analysis, such as voltage (VOC) of 1.18 V, fill factor (FF) of 82.24%, current density (JSC) of 27.12 mA/cm2, power conversion efficiency (PCE) of 27.90% for an incident solar spectrum from the ETL side, and power conversion efficiency (PCE) of 19.86% for an incident solar spectrum from the HTL side, the calculated bifaciality factor (BF) for this structure is 71.18%.

“…The primary mechanism for this is through halide vacancies that exhibit low activation energies in the MHP lattice both intrinsically and under the influence of external stimuli such as heat and light. The consequences of ion migration are phase separation and electrochemical reactions with transport layers and electrodes, affecting their extraction properties that induce material degradation and electronic losses [7,[10][11][12][13] . It has been shown in our previous work that ion migration in PSCs and MHPs can be quantified in terms of a mobile ion concentration (N o ) [6] .…”

Ion migration is one of the prime reasons for the rapid degradation of metal halide perovskite solar cells (PSCs), and we report on a method for quantifying mobile ion concentration (No) using a transient dark current measurement. We perform both ex-situ and in-situ measurements on PSCs and study the evolution of No in films and devices under a range of temperatures. We also study the effect of device architecture, top electrode chemistry, and metal halide perovskite composition and dimensionality on No. Two-dimensional perovskites are shown to reduce the ion concentration along with inert C electrodes that do not react with halides by ~99% while also improving mechanical reliability by ~250%. We believe this work can provide design guidelines for the development of stable PSCs through the lens of minimizing mobile ions and their evolution over time under operational conditions.
