In the backdrop of today's environmental priorities, where toxicity and stability hinder lead‐based perovskite solar cell (PSC) progress, the emergence of lead‐free alternatives like Cs2AgBiBr6 perovskites has gained significance. This study revolves around the comprehensive evaluation of Cs2AgBiBr6 as a potential photovoltaic (PV) material, using density functional theory (DFT) calculations with CASTEP. Revealing a vital bandgap of 1.654 eV and emphasizing the contributions of Ag‐4d and Br‐4p orbitals, this analysis also underscores Ag atoms' dominance in charge distribution. Optically, Cs2AgBiBr6 exhibits UV absorption peaks around 15 eV, intensifying with photon energy up to 3.75 eV, hinting at its promise for solar applications. Guided by DFT, forty configurations involving various electron transport layers (ETLs) and hole transport layers (HTLs) are explored. Among these, CNTS emerges as the prime HTL due to ideal absorber alignment. The spotlight architecture, FTO/AZnO/Cs2AgBiBr6/CNTS/Au, boasts exceptional efficiency (23.5%), Voc (1.38 V), Jsc (21.38 mA cm−2), and FF (79.9%). In contrast, FTO/CdZnS/Cs2AgBiBr6/CNTS/Au achieves a slightly lower 23.15% efficiency. Real‐world intricacies are probed, encompassing resistances, temperature, current–voltage (J–V) traits, and quantum efficiency (QE), enhancing practical relevance. These findings are thoughtfully contextualized within prior literature, showcasing the study's contributions to non‐toxic, inorganic perovskite solar technology. This work aspires to positively steer sustainable PV advancement.

“…Therefore, researchers started exploring non-Si-based thin-film PV cells owing to their potential in the PV market. Low-cost, high-efficiency, simple fabrication techniques, and device architecture are the primary requirements for large-scale PV applications. − However, inevitable charge carrier thermalization and nonabsorption photon losses are the main problems in single-junction devices. Therefore, to diminish these issues, tandem solar cells (TSCs) are employed in the PV industry to increase the efficiency by reducing the abovementioned losses, proving to be a promising approach. ,− In the TSC architecture, two or more solar cells are stacked one over the other to ensure efficient spectrum utilization to minimize thermalization and nonabsorbed photon losses simultaneously.…”

Tandem solar cells have higher efficiency than single-junction devices owing to their wide photon absorption range. A wide band gap (Eg) absorber absorbs the higher-energy photons in the top cell. In contrast, a comparatively low band gap absorber material is utilized in the bottom cell to absorb the filtered low-energy photons. Consequently, thermalization and transparent energy losses are overshadowed by the top subcell (Topsc) and the bottom subcell (Bottomsc), respectively. However, to achieve the best efficiency from a tandem design, the choice of active material in the Topsc and the Bottomsc plays an important role. Therefore, in this proposed study, a tandem solar cell comprising a perovskite (Eg 1.68 eV)-based top cell and a copper indium gallium selenide (CIGS, Eg 1.1 eV)-based Bottomsc has been designed and analyzed. A state-of-the-art Me-4PACz ([4-(3,6-dimethyl-9H-carbazol-9-yl)butyl] phosphonic acid) hole transport layer (HTL) in the perovskite solar cell reported in the previous literature has been considered for the top cell, whereas a calibrated CIGS-based Bottomsc with 16.50% efficiency is designed. Both the Topsc and the Bottomsc are examined for the tandem configuration using filtered spectra and current-matching techniques. In perovskite/CIGS tandem design, an ideal tunnel recombination junction uses Me-4PACz and ITO layers. In a tandem configuration with matched current density at an absorber thickness of 347 nm for Topsc and 2.0 μm for Bottomsc, the device delivered an open-circuit voltage (V OC), current density (J SC), and fill factor (FF) of 1.92 V, 20.04 mA/cm2, and 77%, respectively, resulting in an overall power conversion efficiency (PCE) of 29.7%. The results reported in this work would be beneficial for the development of perovskite-CIGS-based monolithic tandem solar cells in the future.

“…Many strategies have been employed to tackle the phase instability of FAPbI 3 and aim to fabricate high-quality 𝛼-FAPbI 3 perovskite films and achieve high-performance PSCs, including compositional engineering, [12,19] solvent engineering, [11] additive engineering, [9,10,20] intermediate phase engineering, [21,22] dimensionality engineering, [23,24] interfacial engineering, [25,26] and et al, [27][28][29][30][31] Zhao et al utilized CsPbBr 3 perovskite nanocrystals as interfacial ion reservoirs to form a compositional gradient FA 1−x Cs x PbI 3−y Br y layer, effectively protecting the FAPbI 3 perovskite from moisture and achieving operational stability within 500 h. However, this approach only covers the top surface of the bulk perovskite layer, neglecting the moisture vulnerability of FAPbI 3 grain boundaries. [32] In a different approach, Jin et al introduced HCOO − as an additive into the FAPbI 3 perovskite layer, because formate is small enough to fit into the iodide vacancy, showing its ability to passivate defects and improve crystallinity.…”

FAPbI3 perovskites have garnered considerable interest owing to their outstanding thermal stability, along with near‐theoretical bandgap and efficiency. However, their inherent phase instability presents a substantial challenge to the long‐term stability of devices. Herein, this issue through a dual‐strategy of self‐assembly 3D/0D quasi‐core–shell structure is tackled as an internal encapsulation layer, and in situ introduction of excess PbI2 for surface and grain boundary defects passivating, therefore preventing moisture intrusion into FAPbI3 perovskite films. By utilizing this method alone, not only enhances the stability of the FAPbI3 film but also effectively passivates defects and minimizes non‐radiative recombination, ultimately yielding a champion device efficiency of 23.23%. Furthermore, the devices own better moisture resistance, exhibiting a T80 lifetime exceeding 3500 h at 40% relative humidity (RH). Meanwhile, a 19.51% PCE of mini‐module (5 × 5 cm2) is demonstrated. This research offers valuable insights and directions for the advancement of stable and highly efficient FAPbI3 perovskite solar cells.
