“…We have taken two different defect models to study the ion migration phenomenon. [44][45][46][47] In the first model, we have considered defects present at interfacial traps (n + /i and i/p + ) at the junction. In the second model, defects present in the vicinity of the n+ and p+ layer near the junction are considered for hysteresis analysis.…”

Summary Organometal halide perovskite (OHP) has drawn extensive research interest because of its high efficiency, cheap cost, and facile production procedure. However, the commercialization of OHP is still limited owing to its unstable behaviour in open‐air conditions and toxicity due to the presence of lead in commonly used methyalammonium lead perovskite. The mismatch between the current density and voltage curves concerning the scan direction, also known as J‐V hysteresis, is one of the instabilities that creates a serious problem in the overall device performance in MAPbI3 bases perovskite solar cells. In this manuscript, all inorganic lead‐free double perovskite‐based solar cell is computationally simulated, and overall device performance is optimised using solar cell capacitance software. Proposed solar cell is composed of lead‐free Cs2AuBiCl6 double perovskite as the main absorber material and Zn(O, S), CuSCN as an electron transport material and hole transport material, respectively. Due to its high absorption coefficient (≈105 cm−1) and low reflectance, Cs2AuBiCl6 is investigated as a lead‐free double perovskite substitute for OHP. The layered architecture consists of FTO/Zn(O, S)/ Cs2AuBiCl6/CuSCN/Au is optimised by varying the thickness of the absorber layer, the defect density of main absorber layer, interfacial defect and operating temperature. Once the device is optimised, then J‐V hysteresis is performed using two different defect model‐based strategies. Simulation finding gives decent power conversion efficiency of 20.5% with almost negligible hysteresis. These simulation‐based studies on Cs2AuBiCl6 will give guidance for designing and developing a high‐efficiency eco‐friendly lead‐free perovskite solar cell as an alternative to traditional lead‐based perovskite solar cells.

The quality of the perovskite film is crucial to the technological breakthrough of perovskite solar cells (PSCs). The two‐step method can facilitate the formation of a perovskite film with high quality and reproducibility. Many milestones have been made in the development of hybrid lead halide PSCs by using the two‐step method, which has a significant impact on their practical application. Herein, the reaction mechanism of the two‐step method including two‐step immersion method and two‐step spin coating method is summarized. The strategies such as component engineering, solvent engineering, and additive engineering of the two‐step method in preparing high‐quality films are introduced systematically and in detail. In addition, current issues of the two‐step method and its applications in lead‐free PSCs, all‐inorganic PSCs, large areas, and tandems are introduced and some suggestions are put forward for future research.
