Опубликована: Фев. 4, 2025

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.

Buried interface in perovskite solar cells (PSCs) is a critical determination for the performance and stability because it dominates crystallization of layer, non-radiative recombination, ion migration at interfaces. Herein, novel versatile modifier, potassium sucrose octasulfate (K8SOS) which rich sulfonic groups ions, introduced bridging buried SnO2 interface, to improve interfacial states further device performance. It found that K8SOS serves as bridge can not only passivate defects through multi-site strengthening chemical binding, thus effectively inhibiting non-radiation recombination suppressing migration, but also optimize surface state absorber, ultimately achieving gratifying efficiency 25.32% with negligible hysteresis. What's more, optimized delivers admirable sustaining over 90% initial power conversion after being aged under continuous 85 °C heating stress 40 ± 5% RH humidity ≈600 ≈1200 h 1-sun illumination, respectively.
