Abstract Layer-structured Ruddlesden–Popper (RP) perovskites (RPPs) with decent stability have captured the imagination of photovoltaic research community and bring hope for boosting development perovskite solar cell (PSC) technology. However, two-dimensional (2D) or quasi-2D RP PSCs are encountered some challenges large exciton binding energy, blocked charge transport poor film quality, which restrict their performance. Fortunately, these issues can be readily resolved by rationally designing spacer cations RPPs. This review mainly focuses on how to design molecular structures organic spacers aims endow RPPs outstanding applications. We firstly elucidated important roles in impacting crystallization kinetics, transporting ability Then we brought three aspects attention spacers. Finally, presented specific structure strategies aiming improve performance PSCs. These proposed this will provide new avenues develop novel advance RPP technology future

Abstract The utilization of wide bandgap (WBG) tin halide perovskites (Sn‐HPs) offers an environmentally friendly alternative for multi‐junction Sn‐HP photovoltaics. Nonetheless, rapid crystallization leads to suboptimal film morphology and substantial creation defect states, which undermine device efficiency. This study introduces 4‐Phenylthiosemicarbazide (4PTSC) as additive achieve a densely packed with fewer imperfections. strong chemical coordination between SnI 2 the functional groups S═C─N (Sn···S═C─N), NH , phenyl conjugation enhances solution stability supports delay perovskite through adduct formation. process yields pinhole‐free films preferred grain growth. 4PTSC acts complex reducing agent passivate uncoordinated Sn 2+ ions reduce formation 4 thereby π‐conjugated ring in facilitates crystal growth orientation grains. Furthermore, hydrophobic nature mitigates oxidation by repelling moisture, enhancing stability. open circuit voltage significantly increased from 0.78 0.94 V, resulting achieving champion efficiency 12.22% (certified 11.70%), surpassing all previously reported efficiencies WBG solar cells. Additionally, unencapsulated 4PTSC‐1.0 maintained outstanding over 1200 h under ambient atmospheric conditions.

Two-dimensional (2D) organic–inorganic metal halide perovskites have gained immense attention as alternatives to three-dimensional (3D) in recent years. The hydrophobic spacers the layered structure of 2D make them more moisture-resistant than 3D perovskites. Moreover, they exhibit unique anisotropic electrical transport properties due a structural confinement effect. In this study, four lead-free Dion–Jacobson (DJ) Sn-based phase perovskite single crystals, 3AMPSnI4, 4AMPSnI4, 3AMPYSnI4, and 4AMPYSnI4 [AMP = (aminomethyl)-piperidinium, AMPY (aminomethyl)pyridinium] are reported. Results reveal differences between impacting resulting optical properties. Namely, higher octahedron distortion results absorption edge. Density functional theory (DFT) is also performed determine trends energy band diagrams, exciton binding energies, formation energies among crystals. Finally, field-effect transistor (FET) based on 4AMPSnI4 demonstrated with respectable hole mobility 0.57 cm2 V–1 s–1 requiring low threshold voltage only −2.5 V at drain −40 V.
