While laser wireless power transfer (LWPT) technology possesses transformative potential for powering autonomous underwater vehicles, converters (LPCs) based on conventional III–V materials experience significant efficiency losses in aquatic environments. As a superior alternative candidate, wide‐bandgap formamidinium lead bromide (FAPbBr 3 ) perovskite demonstrates considerable achieving highly efficient LPCs. However, FAPbBr is often susceptible to various bulk and interfacial defects due its rapid uncontrollable crystallization process, rendering the formation of uniform dense α ‐phase films challenging. In this study, dual‐additive strategy introduced, wherein rubidium iodide (RbI) cooperates with methylammonium chloride (MACl) facilitate attainment high‐quality crystals. result, RbI‐treated LPC achieves champion conversion 54.03% under 70 mW cm −2 @ 532 nm irradiation. Moreover, device exhibits significantly enhanced long‐term storage ( T 92 25°C 1800 h) thermal stability 90 80°C 500 h). This work provides valuable insights foundational knowledge development LPCs their application LWPT systems.

Abstract The rapid expansion of the Internet Things demands low‐power devices that integrate memory, sensors, and logic functions. Perovskite materials show promise for optoelectronic memristors; however, challenges such as nonuniform trap distribution uncontrolled filament formation hinder their resistive switching performance. To overcome these issues, a TiO 2 nanofilm via atomic layer deposition base formation, is introduced. This passivates interfacial defects by forming strong chemical interactions with Pb 2+ I − ions at perovskite interface, significantly reducing densities (interface density decreases 15‐fold to 3.0 × 10 16 cm −3 , bulk 1.8 14 ). Improved energy band alignment enables efficient electron transport, yielding low‐ V SET (+0.24 V) excellent (≈0.7 µW) nonvolatile memory Additionally, device reliably detects near‐infrared illumination an optical input reconfigurable image recognition using 5 array under combined stimuli. It also facilitates implementation complex gates, AND, OR, flip‐flops. paper demonstrates potential integrating sensing, functionalities into single through incorporation nanolayer.

Abstract Surface termination is so far the mainstream passivating method to enhance performance of CsPbI 3 solar cells. However, surface can hardly achieve effective and homogeneous passivation on large‐area films, which one key challenge toward high‐performance inorganic perovskite modules (PSMs). The strong ionic bond between Cs Pb‐I framework in makes it difficult construct 2D layer film via post treatment, otherwise a classic effectual approach for defect elimination organic–inorganic hybrid perovskites. Herein, novel programmable reconstruction strategy reported that facilely tune using 2‐(1‐cyclohexenyl) ethyl ammonium iodide (CHEAI). In comparison termination, situ formation CHEA 2 PbI 4 by adjusting stoichiometry CHEAI demonstrates more comprehensive effects favorable energy level alignment films. Such construction has greatly facilitated enhancement device performance, especially when scaling up area. optimal PSM (active area 12.44 cm ) based achieves record‐high efficiency 19.32% (certified 18.83%) with much improved stability, endorsing practical promotion this intrinsically stable material.

Inorganic CsPbI2Br perovskite solar cells have attracted widespread attention due to their outstanding performance and photo-thermal stability. However, the rapid crystallization of solution-processed film often results in poor crystallinity a high density defects, which seriously restrict improvement device performance. Here, we introduce dual-functional additive, 4-amino-5-aminomethyl-2-methylpyrimidine (AMP), regulate reduce defect film. The introduction AMP notably improves morphology promotes preferred crystal orientation. C=N amino groups interact with Pb2+ Br- perovskite, respectively, effectively passivating defects improving carrier lifetime. As result, power conversion efficiency optimized carbon-based hole-transport layer-free reaches 13.30%, exceeds 10.66% control device. environmental light stability is also significantly improved. This work provides valuable insights into development high-performance all-inorganic via additive strategies.
