Perovskite solar cells (PSCs) can produce solar energy that is both affordable and highly effective. Still, they currently face challenges in achieving peak performance in important areas, including sustainability, stability, and efficiency. Recent studies examine tandem perovskite solar cells based on CsPbI3 in great detail, analyzing their photovoltaic characteristics with SCAPS 1D software. This work examines the effects of multiple parameters on performance metrics, including power conversion efficiency (PCE), fill factor (FF), open-circuit voltage (Voc), and short-circuit current (Jsc), with a focus on a multi-layered design. The photoactive layer thickness, defect densities, electrode contact quality, and operation temperatures are the factors. Compared to conventional lead-based perovskites, CsPbI3 offers advantages in terms of long-term stability, reduced moisture susceptibility, and reduced lead toxicity. However, there is an issue with achieving efficiency levels comparable to MAPbI3 and FAPbI3. The research reveals correlations between material properties and device performance by applying advanced diagnostic techniques like quantum efficiency (QE), carrier concentration, and recombination rate analysis. This information has the potential to result in material enhancements and device optimization. With a particular focus on CsPbI3, the work offers crucial insights into tandem perovskite solar cells that will advance the creation of more reliable, effective, and sustainable solar energy systems.
