    Navigating Challenges and Promises for Next-Generation CsPbIBr2 Perovskite Solar Cells: A Review
    (Wiley, 2024-09) Aamir, Muhammad; Hossain, Mohammad Ismail; Akhtaruzzaman, Md.; Rafij, Junayed Hossain; Uddin, Jamal; Akhtar, Javeed; Amin, Nowshad; EL Ganaoui, Mohammad; Nunzi, Jean-Michel; Taima, Tetsuya; Shahiduzzaman, Md.
    Given the increasing demand for electricity due to modernization and population growth, there is an urgent need to develop renewable energy conversion technologies such as photovoltaics. Among these technologies, CsPbIBr2, an all-inorganic lead halide-based perovskite, has shown promise due to its thermal stability, phase stability, and ease of fabrication. However, challenges remain, particularly in addressing device hysteresis and stability. Novel materials and optimized device designs could help overcome these challenges. This comprehensive review discusses strategies such as interface engineering, film quality improvement, compositional engineering, defect passivation, band alignments, and metal ion doping to enhance the performance of CsPbIBr2-based perovskite films and, in turn, their potential for photovoltaic applications.

    Revealing the full potential of CsPbIBr2 perovskite solar cells: advancements towards enhanced performance
    (Royal Society of Chemistry, 2024-06) Hossain, Mohammad Ismail; Shahiduzzaman, Md.; Rafij, Junayed Hossain; Tamang, Asman; Akhtaruzzaman, Md.; Hamad, Almohamadi; Uddin, Jamal; Amin, Nowshad; Nunzi, Jean-Michel; Taima, Tetsuya
    Cesium lead iodide bromide (CsPbIBr2) perovskite solar cells (PSCs) have improved stability compared to other perovskite compositions. However, they still face significant challenges due to their poor photovoltaic performance parameters, which limit the devices’ power conversion efficiencies (PCEs). This study proposes a novel device design to tailor the potential of CsPbIBr2 PSCs by improving their optoelectronic properties. An advanced 3D multiphysics approach was rigorously used to investigate the optics and electrical properties of the proposed CsPbIBr2 PSCs. This approach combines finite-difference time-domain (FDTD) and finite element method (FEM) techniques with the particle swarm optimization (PSO) algorithm. The outcome from the adapted numerical approach is in good agreement with the experimental results. The optimized CsPbIBr2 PSC demonstrates a promising power conversion efficiency (PCE) of over 16.4%, associated VOC of 1.53 V, FF of 80.6%, and JSC of 13.4 mA cm2. Therefore, the potential of CsPbIBr2 perovskites could be further explored with continued research and development in material science and device physics.
