Abstract Cs₂SnI₆ has emerged as a stable and environmentally friendly replacement for lead (Pb)‐based perovskite solar cells (PSCs) due to its air stability, attributed the Sn⁴⁺ oxidation state, non‐toxic composition (lead‐free). A key benefit of using an absorber layer is that it enables elimination hole transport layers (HTLs) in some device architectures; however, PSCs with HTLs generally outperform those without HTL. Here, structural, electronic, optical properties are investigated first‐principles calculations, photovoltaic effects by SCAPS‐1D simulation software. Nine different configurations have been combining three electron (ETLs) optimize performance. The impact HTL thickness, ETL operating temperature studied on cell's efficiency. optimized PSC demonstrates fill factor (FF) 84.683%, power conversion efficiency (PCE) 24.0%, short circuit current density J SC 28.433 mA cm −2 , open voltage V OC 0.998 V, quantum 99.866%, optimal conditions at 300 K.

All‐Inorganic Tin‐Containing Perovskite Solar Cells: An Emerging Eco‐Friendly Photovoltaic Technology

Advanced Materials, Год журнала: 2025, Номер unknown

Опубликована: Май 12, 2025

Abstract All‐inorganic tin (Sn)‐containing perovskites have emerged as highly promising photovoltaic materials for single‐junction and tandem perovskite solar cells (PSCs), owing to their reduced toxicity, optimal narrow bandgap, superior thermal stability. Since initial exploration in 2012, significant advancements been achieved, with the highest efficiencies of devices now surpassing 17% 22%, respectively. Nevertheless, intrinsic challenges associated oxidation susceptibility Sn 2+ uncontrolled crystallization dynamics impede further development. Addressing these issues necessitates a comprehensive systematic understanding degradation mechanisms inherent all‐inorganic Sn‐containing perovskites, well development effective mitigation strategies. This review provides detailed overview research progress PSCs, particular focus on basic properties pathways both pristine mixed Sn‐Pb perovskites. Furthermore, various strategies improve efficiency stability PSCs are thoroughly discussed. Finally, existing perspectives provided improving performance eco‐friendly PSCs.
