In recent years, perovskite solar cells (PSCs) have appeared as frontrunners in the renewable photovoltaic (PV) landscape. This study presents a substantially improved perovskite material, showcasing enhanced optoelectronic performance and potential for streamlined fabrication processes. Our main focus lies in identifying the optimal cesium halide composition, in conjunction with TiO 2 and CuI as charge transport layers (CTLs), that yield the highest efficiency. Through meticulous optimization encompassing absorber thickness, CTL thickness, defect density, and interface properties, our findings reveal that CsPbI 2 Br-based PSCs exhibit a remarkable boost in power conversion efficiency (PCE) of approximately 15.52%. In contrast, CsPbBr 3 -based PSCs exhibit comparatively lower values for short-circuit current density (J SC ) and open circuit voltage (V OC ), which results in a PCE of 13.96%. This investigation extends to exploring various parameters, including temperature effects, impedance characteristics, series resistance, quantum efficiency (QE), and current− voltage (J−V) behavior. The comprehensive nature of this study bears substantial significance in advancing the efficient fabrication of cesium-based PSC devices. The demonstrated perovskite material holds immense promise across diverse applications in the foreseeable future, owing to its cost-effectiveness and favorable optical absorption properties.

“…The optimized device recorded a PCE of 28.4% using a low defect density of 10 14 cm −3 (L n = 50 μm and L p = 23 μm). 37 As aforementioned in the above discussion, we believe that the very high efficiency of the simulated CsSn 0.5 Ge 0.5 I 3 device is because of the overstimulation in the diffusion lengths of photocarriers for the perovskite film, while to the best of our knowledge, the diffusion lengths of the CsSnI 3 -based perovskite film can only be approached to 1 μm. 38 To predict optimal values for best performance from the photovoltaics, a comprehensive study of the interplay between the many factors that impact CsSn 0.5 Ge 0.5 I 3 absorbers is required.…”

Due to their enhanced performance and simplicity in manufacturing, scalability, and versatility, lead-halide perovskite-based solar cells (HPSCs) have received much attention in the domains of energy. Lead is present in nature as a poisonous substance that causes various issues to climate and human health and prevents its further industrialization. Over the past few years, there has been a noticeable interest in exploring some alternative lead-free perovskites. However, owing to some intrinsic losses, the performance that may be achieved from these photovoltaics is not up to standards. Thus, for the purpose of efficiency improvement, a comprehensive simulation is required to comprehend the cause of these losses. In the current research, an investigation into how to employ the promisingly efficient lead-free, allinorganic cesium tin−germanium iodide (CsSnGeI 3 ) perovskites as the photoactive layer in HPSCs was performed. Results exhibited a high efficiency of 12.95% with a CsSn 0.5 Ge 0.5 I 3 perovskite thickness of 0.6 μm and a band gap of 1.5 eV at room temperature. High efficiency may be achieved using phenyl-C61-butyric acid methyl ester (PCBM) as an electron transport material because of its favorable energy-level alignment with the perovskite material. The research further tested the perovskite layer thickness and defect density in depth. The results showed that the carrier diffusion lengths have a big effect on how well the HPSC works.

Multi‐absorbers, and tandem solar cells (TSCs), have enticed research focus with their competitive advantage of crossing the limits posed by Shockley–Queisser efficiency by single‐junction solar cell (SC). Perovskite solar cells (PSC) with their bandgap tunability and ease of solution processing at low temperatures for securing high efficiency (25.8%) provide an ideal candidate for top cell in TSC. Simultaneously, Si SCs with a 95% market share and their ideal low bandgap (1.12 eV) for capturing high‐energy photons in the near‐infrared (NIR) can assume bottom cell in TSC. This review highlights the research perspective for perovskite/Si TSCs to expedite its emergence as future TSC. The 4T device architecture of perovskite/Si TSC optically couples the subcells whereas the 2T configuration ensures the optical and electrical coupling among the constituent subcells. The semitransparency of the top cell, flat as well as textured Si bottom cell, matching of the current between the subcell through the recombination and tunnel junction layers, and modification of perovskites through‐thickness variation are few worth‐considering factors that contribute toward highly efficient perovskite/Si TSC. Finally, the research insight about perovskite/Si and all‐perovskite TSC is analyzed with reference to the ideal choice for the bottom cell.
