Dynamic Isomers Fortify Perovskite Grain Boundaries Under Cyclic Illumination

Perovskite solar cells (PSCs) are a promising photovoltaic technology, yet their commercialization is hindered by insufficient long-term operational stability under real-world conditions. While progress has improved resilience against static stressors (constant heat, electrical bias, humidity), durability under dynamic outdoor environments—particularly diurnal light cycling and temperature fluctuations—remains inadequately understood. Cyclic illumination induces interfacial expansion and contraction, leading to mechanical stress accumulation and grain-boundary (GB) fragmentation, ultimately decomposing the perovskite into Pb2+ and inactive phases. To address this, Zhang et al. propose a dynamic GB-resilience strategy integrating a photoswitchable isomeric compound, 4-(phenylazo) benzoic acid (Ca-Abz), into triple-cation lead-based perovskite grain boundaries. In the dark, Ca-Abz adopts a planar trans (E) configuration, anchoring via carboxylic acid-Pb2+ coordination. Under UV illumination, electronic excitation lowers the rotational barrier of the azo bond, triggering a transition to a sterically twisted cis (Z) configuration. This reversible molecular switching dynamically accommodates periodic lattice expansion and contraction, dissipating intergranular stress and regulating local strain. Density functional theory and first-principles molecular dynamics simulations show the Z isomer binds slightly stronger to the perovskite surface (−11.01 eV) than the E isomer (−10.99 eV), indicating illumination actively strengthens passivation. This approach represents a shift from static passivators to stimuli-responsive interfacial regulators that utilize UV energy to stabilize grain boundaries during lattice expansion, offering a promising route to enhance PSC operational stability under cyclic illumination.

Engineering Hydrogen-Bond Networks in Self-Assembled Molecules Boosts All-Perovskite Tandem Solar Cell Efficiency

All-perovskite tandem solar cells (TSCs) are poised to surpass the Shockley–Queisser limit of single-junction perovskite solar cells (PSCs) by integrating wide- and narrow-bandgap subcells to broaden spectral utilization. However, their performance remains constrained by interface charge transfer losses and non-radiative recombination in wide-bandgap subcells. Self-assembled monolayers (SAMs) serve as effective hole-selective contacts, yet conventional designs suffer from uncontrolled intermolecular interactions due to amphiphilic characteristics, leading to detrimental self-aggregation, suboptimal molecular packing, and weakened interfacial adhesion. In a recent breakthrough published in Nature Energy, Wang et al. introduced a rational molecular design that integrates amide units as dual hydrogen-bond donors and acceptors into a bicarbazole-based biphosphonic acid dimer (AOCzPA). This design suppresses self-aggregation via a twisted conformation of the C–C-linked carbazole dimer, enhancing steric hindrance and preventing π–π stacking. The amide groups establish an expansive, cooperative hydrogen-bonding network, forming intramolecular bonds, intermolecular connections, and strengthened bonds with hydroxylated transparent conductive oxides (TCO) via C=O···HO–In/Sn and N–H···O–In/Sn. This network impedes long-range crystalline order, creating an amorphous, homogeneous molecular distribution without nanovoids. Consequently, the energy band at the perovskite interface bends upward, narrowing the energy offset to 0.42 eV and aligning HOMO levels for barrier-free hole extraction. The strategy yields exceptional performance: 1.77 eV single-junction wide-bandgap PSCs achieve a PCE of 21.56%, V_OC of 1.35 V, and FF of 85.76%, indicating low voltage losses and suppressed non-radiative recombination. This work advances SAM design from monolayer assembly to networked interface engineering, enhancing mechanical and chemical robustness and minimizing hole-transport losses.

Oxide-channel ferroelectric transistor enables ultralow-power NAND flash technology

The escalating power consumption of 3D NAND flash memory, driven by the need for high pass voltages (V_pass) to read cells in vertically stacked strings, poses a critical challenge as layer counts approach 1000. Conventional charge-trap NAND requires V_pass of 5–10 V for quad-level cell (QLC) operation, while silicon-channel ferroelectric NAND suffers from limited memory windows due to low-k interlayers. Here, we highlight a breakthrough by Yoo et al. that introduces an oxide semiconductor (OS)-channel ferroelectric field-effect transistor (FeFET) with a gate stack comprising a zirconium-doped hafnium oxide (HZO) ferroelectric layer sandwiched between low-k (SiO2/SiNx) and high-k (Ta2O5) interlayers, and an indium gallium zinc oxide (IGZO) channel. The absence of hole carriers in IGZO suppresses the 'down' polarization state, enabling a near-zero threshold voltage (V_th) and reducing V_pass to as low as 1 V. The high-k Ta2O5 interlayer prevents oxygen diffusion, mitigating off-current degradation, while the low-k SiO2/SiNx interlayer enhances charge trapping, yielding a memory window exceeding 11 V for a 5-nm SiO2 layer. This enables 5-bit-per-cell (penta-level cell, PLC) operation, surpassing current QLC NAND. The combination of ultralow V_pass and wide memory window achieves both low power consumption and high storage density, positioning OS-channel FeFETs as a promising solution for next-generation memory systems.

Slidable van der Waals Layers in Wearable Medical Monitoring: Structural Regulation Logic and Design Principles for Flexible Bioelectronics

Wearable medical monitoring devices require conformal, long-term tissue integration, yet conventional rigid electronics fail to accommodate dynamic tissue deformation. This highlight examines the structural regulation logic of slidable van der Waals (vdW) layers as an instructive design paradigm for flexible bioelectronic materials. The approach leverages weak interlayer interactions to enable adaptive sliding, reducing interfacial stress and enhancing mechanical compliance. Key advances include spray-based fabrication, which offers scalability and cost-effectiveness for industrial translation. The strategy addresses bottlenecks in deep-tissue dynamic physiological monitoring, where existing interfaces suffer from mechanical mismatch and signal degradation. By tuning mechanical performance, enabling low-cost mass manufacturing, and integrating multi-hardware systems, this interface strategy promises to accelerate the transition from laboratory prototypes to clinical and consumer wearable devices. The highlight synthesizes recent literature, including a movable long-term implantable soft microfibre (Nature, 2025) and drawn-on-skin electronic tattoos (Sci Adv, 2026), to contextualize the vdW sliding approach. Quantitative metrics from these studies—such as mechanical compliance, operational stability, and fabrication throughput—are discussed to underscore industrial viability. The findings suggest that vdW layer sliding can be engineered to achieve fatigue resistance and conformal contact, critical for chronic implantation. This work provides a framework for designing next-generation bioelectronic interfaces, with implications for personalized medicine and remote health monitoring.

Synergy of Dynamic Covalent Bonds and Hydrogen Bonds Enables Dual Dynamic Recyclable Helical Polymers

Biopolymers such as proteins exhibit both stability and dynamic properties, reflected in precise conformational adaptability and reversibility within cells. Simulating this dual dynamic nature in fully synthetic covalent polymers has been a major challenge, aiming to enable a single material to reversibly transform between defined helical conformations and random coils, and to be fully recycled back to original building units. Recently, Zhang, Qu, Feringa and co-workers reported a groundbreaking advance in Nature Chemistry, achieving a helical covalent polymer with reversible conformational switching between ordered and disordered states while maintaining complete chemical recyclability to its monomers. This system is built on poly(disulfide)s, utilizing biologically relevant building blocks (1,2-dithiolane asparagusic acid, AA) and amino acid derivatives. Monomers undergo reactive ring-opening polymerization (ROP) initiated by sodium bisulfate under mild conditions, forming polymers that exhibit reversible conformational interconversion between disordered coils and helical structures. Incorporation of a dipeptide motif (AA-L-Ala-L-Ala) establishes stable extended β-sheet-like hydrogen bonds, improving helical stability. Following polymerization, nanocrystalline polymers can be reorganized into semicrystalline structures upon thermal treatment, yielding rod-like flexible cylinders approximately 2.1 nm in diameter and 25 nm in length. Structural analyses reveal hierarchical organization, including β-sheet-stabilized rod-like flexible cylinders and columnar liquid crystal assemblies, imparting remarkable thermal stability and conformational resilience. The dual energy landscapes govern monomer-polymer equilibrium and conformation-dependent closed-loop recycling, enabling intrinsic reconfigurability among small-molecule monomers, random coils, and helical poly(disulfide)s, triggered by temperature.
