Organic-inorganic metal-halide perovskites have received great attention for photovoltaic (PV) applications owing to their superior optoelectronic properties and the unprecedented performance development. For single-junction PV devices, although lead (Pb)-based perovskite solar cells achieved 26.1% efficiency, mixed tin-lead (Sn-Pb) offer more ideal bandgap tuning capability enable an even higher performance. The Sn-Pb (with a tuned ≈1.2 eV) is also attractive as bottom subcell tandem configuration further surpass Shockley-Queisser radiative limit devices. of all-perovskite has gained rapid development certified efficiency up 29.1%. In this article, recent state-of-the-art application in are reviewed. Recent advances various approaches covering additives, solvents, interfaces, growth highlighted. authors provide perspective outlook on challenges strategies both stability applications.

Abstract Tin‐lead (Sn‐Pb) mixed perovskite with a narrow bandgap is an ideal candidate for single‐junction solar cells approaching the Shockley‐Queisser limit. However, due to easy oxidation of Sn 2+ , efficiency and stability Sn‐Pb (PSCs) still lag far behind that Pb‐based cells. Herein, highly efficient stable FA 0.5 MA Pb I 0.47 Br 0.03 compositional PSCs are achieved by introducing appropriate amount multifunctional Tin (II) oxalate (SnC 2 O 4 ). SnC compensative reductive group C 2− effectively passivates cation anion defects simultaneously, thereby leading more n‐type films. Benefitting from energy level alignment suppression bulk nonradiative recombination, cell treated achieves power conversion 21.43%. More importantly, chemically suppresses notorious significant enhancement in stability. Particularly, it dramatically improves light

Space-charge-limited current (SCLC) measurements play a crucial role in the electrical characterization of semiconductors, particularly for metal halide perovskites. Accurate reporting and analysis SCLC are essential gaining meaningful insights into charge transport defect density these systems. Unfortunately, performing on perovskites is complicated by their mixed electronic-ionic conductivity. This complexity led to data often being incorrectly analyzed using simplified models unsuitable materials reported without information about how were performed. In light recently published data, common challenges perovskite addressed, solutions discussed this paper. The applicability often-used analytical models, overlooked issues related ionic-electronic conductivity perovskites, creating single-carrier devices investigated drift-diffusion simulations. Finally, guidelines more accurate improved provided.

Narrow bandgap mixed tin-lead perovskite solar cells (PSCs) have garnered substantial research interest owing to their remarkable optoelectronic properties. However, non-radiative recombination and carrier transport losses at the interface between layer charge (C60) significantly reduce overall efficiency of PSCs. To address this challenge, 9-Fluorenylmethyl carbazate (9FC) is incorporated C60. The hydrazide group present in 9FC effectively mitigates oxidation Sn2+. Furthermore, can engage chemical bonding with perovskite, while outward-facing aromatic rings create effective π-π interactions C60, thereby promoting enhanced interfacial transfer. highest-performing PSCs achieve a power conversion (PCE) 23.97%, accompanied by an impressive open-circuit voltage 0.91 V. Additionally, these facilitate development highly efficient two-terminal four-terminal all-perovskite tandem cells, which demonstrate efficiencies 27.01% 28.07%, respectively.

Abstract Precise control over halide perovskite crystallization is pivotal for realizing efficient solar cells. Here, we introduce a strategy utilizing in-situ-formed oxide-based ABX 3 -structured seeds to regulate and growth. Introducing potassium stannate into precursors triggers spontaneous reaction with lead iodide, producing iodide stannate. Potassium effectively passivates defects, while PbSnO (ABX -structured), exhibiting 98% lattice match, acts as template seed. This approach facilitates pre-nucleation cluster formation, preferential grain orientation, the elimination of intermediate-phase processes in films. Incorporating both buried hole transport layers enables single-junction 1.25 eV-bandgap Sn-Pb cells achieve steady-state efficiency 23.12% enhanced stability. Furthermore, all-perovskite tandem devices yield efficiencies 28.12% (two-terminal) 28.81% (four-terminal). versatile templating method also boosts performance 1.77 eV 1.54 cells, underscoring its broad applicability.

Slowing hot carrier (HC) cooling in halide perovskites emerges as an efficient strategy to enhance the power conversion efficiency (PCE) of perovskite solar cells (PSCs). This approach facilitates rapid extraction HCs before they dissipate within intricate lattice structure. In this investigation, we delve into impact amine-based additives on relaxation using a diamine 4,4′-diaminodiphenylmethaneiodide salt (MDA). The has been used situ additive precursor. ultrafast femtosecond transient absorption (fs-TA) spectroscopy study confirms that diamine-modified film slows HC time 672 fs from control (538 fs). Moreover, MDA helps improve crystallization and passivate traps for inhibiting nonradiative recombination, leading higher PCE compared device. passivated devices show impressive ambient stability retain 80% initial after 500 h. Our provides in-depth understanding how precise through engineering can PSC's stability.
