Printing of large-area solar panels necessitates advanced organic solar cells with thick active layers. However, increasing the active layer thickness typically leads to a marked drop in the power conversion efficiency. Here we developed an organic semiconductor regulator, called AT-β2O, to tune the crystallization sequence of the components in active layers. When adding AT-β2O in the donor (D18-Cl) and acceptor (N3) blend, N3 crystallizes behind D18-Cl, and this phenomenon is different from the co-crystallization observed in binary D18-Cl:N3 blends. This manipulation of crystallization dynamics is favourable to form bulk-heterojunction-gradient vertical phase separation in the active layer accompanied by the high crystallinity of the acceptor and balanced charge carrier mobilities in thick films. The resultant single-junction organic solar cells exhibited a certified power conversion efficiency of over 20%, as well as demonstrated exceptional adaptability across the active layer thicknesses (100–400 nm) and remarkable universality. Such breakthroughs enable large-area modules with a certified power conversion efficiency of 18.04%. An organic regulator that can tune the crystallization sequence of active layer components has been described, achieving a certified efficiency of over 20% in single-junction organic solar cells, demonstrating remarkable tolerance for active layer thickness of 100–400 nm.

Directed collective cell migration is essential for morphogenesis, and chemical, electrical, mechanical and topological features have been shown to guide cell migration in vitro. Here we provide in vivo evidence showing that endogenous electric fields drive the directed collective cell migration of an embryonic stem cell population—the cephalic neural crest of Xenopus laevis. We demonstrate that the voltage-sensitive phosphatase 1 is a key component of the molecular mechanism, enabling neural crest cells to specifically transduce electric fields into a directional cue in vivo. Finally, we propose that endogenous electric fields are mechanically established by the convergent extension movements of the ectoderm, which generate a membrane tension gradient that opens stretch-activated ion channels. Overall, these findings establish a role for electrotaxis in tissue morphogenesis, highlighting the functions of endogenous bioelectrical stimuli in non-neural contexts. Electric fields guide collective cell migration in developing embryos of Xenopus laevis via a voltage-sensitive phosphatase.

A successful therapeutic outcome in the treatment of solid tumours requires efficient intratumoural drug accumulation and retention. Here we demonstrate that zinc gluconate in oral supplements assembles with plasma proteins to form ZnO nanoparticles that selectively accumulate into papillary Caki-2 renal tumours and promote the recruitment of dendritic cells and cytotoxic CD8+ T cells to tumour tissues. Renal tumour targeting is mediated by the preferential binding of zinc ions to metallothionein-1X proteins, which are constitutively overexpressed in Caki-2 renal tumour cells. This binding event further upregulates intracellular metallothionein-1X expression to induce additional nanoparticle binding and retention. In both tumour animal models and human renal tumour samples, we show that ZnO nanoparticles actively cross the vascular wall to achieve high intratumoural accumulation. We further explore this feature of ZnO nanoparticles for the delivery of chemotherapeutics to mouse and rabbit cancer models. Our findings demonstrate that ZnO nanoparticles derived from supplements can serve as a multifunctional drug delivery and cancer immunotherapy platform. Zinc gluconate in oral supplements associates with plasma proteins to form renal-tumour-accumulating ZnO nanoparticles, which have antitumoural immune activity and can also be used for the delivery of chemotherapeutic agents.

Polymorphism, commonly denoting diverse molecular or crystal structures, is crucial in the natural sciences. In van der Waals antiferromagnets, a new type of magnetic polymorphism arises, presenting multiple layer-selective magnetic structures with identical total magnetization. However, resolving and manipulating such magnetic polymorphs remain challenging. Here, phase-resolved magnetic second harmonic generation microscopy is used to elucidate magnetic polymorphism in 2D layered antiferromagnet CrSBr, demonstrating deterministic and layer-selective switching of magnetic polymorphs. Using a nonlinear magneto-optical technique, we unambiguously resolve the polymorphic spin-flip transitions in CrSBr bilayers and tetralayers through both the amplitude and phase of light. Remarkably, the deterministic routing of polymorphic spin-flip transitions originates from a ‘layer-sharing’ effect, where the transitions are governed by laterally extended layers acting as ‘control bits’. We envision that such controllable magnetic polymorphism could be ubiquitous for van der Waals layered antiferromagnets, enabling new designs and constructions of spintronic and opto-spintronic devices for probabilistic computation and neuromorphic engineering. The authors report on their observation of magnetic polymorphs in CrSBr using phase-sensitive second harmonic generation.

The shape of biological matter is central to cell function at different length scales and determines how cellular components recognize, interact and respond to one another. However, their shapes are often transient and hard to reprogramme. Here we construct a synthetic cell model composed of signal-responsive DNA nanorafts, biogenic pores and giant unilamellar vesicles (GUVs). We demonstrate that reshaping of DNA rafts at the nanoscale can be coupled to reshaping of GUVs at the microscale. The nanorafts collectively undergo reversible transitions between isotropic and short-range local order on the lipid membrane, programmably remodelling the GUV shape. Assisted by the biogenic pores, during GUV shape recovery the locally ordered DNA rafts perforate the membrane, forming sealable synthetic channels for large cargo transport. Our work outlines a versatile platform for interfacing reconfigurable DNA nanostructures with synthetic cells, expanding the potential of DNA nanotechnology in synthetic biology. The shape of biological matter is central to their function and interaction with other cellular components. A combination of DNA origami nanorafts with biogenic pores reversibly controls the shape and permeability of lipid vesicles at the microscale.

Batch production of single-crystal two-dimensional (2D) transition metal dichalcogenides is one prerequisite for the fabrication of next-generation integrated circuits. Contemporary strategies for the wafer-scale high-quality crystallinity of 2D materials centre on merging unidirectionally aligned, differently sized domains. However, an imperfectly merged area with a translational lattice brings about a high defect density and low device uniformity, which restricts the application of the 2D materials. Here we establish a liquid-to-solid crystallization in 2D space that can rapidly grow a centimetre-scale single-crystal MoS2 domain with no grain boundaries. The large MoS2 single crystal obtained shows superb uniformity and high quality with an ultra-low defect density. A statistical analysis of field effect transistors fabricated from the MoS2 reveals a high device yield and minimal variation in mobility, positioning this FET as an advanced standard monolayer MoS2 device. This 2D Czochralski method has implications for fabricating high-quality and scalable 2D semiconductor materials and devices. A 2D Czochralski method is introduced for rapidly growing centimetre-scale single-crystal MoS2 domains with low defect density and impressive electrical performance. This method shows potential for fabricating high-quality and scalable 2D semiconductor materials and devices.

Monolithic all-perovskite tandem solar cells present a promising approach for exceeding the efficiency limit of single-junction solar cells. However, the substantial open-circuit voltage loss in the wide-bandgap perovskite subcell hinders further improvements in power-conversion efficiency. Here we develop wide-bandgap perovskite films with improved (100) crystal orientation that suppress non-radiative recombination. We show that using two-dimensional perovskite as an intermediate phase on the film surface promotes heterogeneous nucleation along the (100) three-dimensional perovskite facets during crystallization. Preferred (100) orientations can be realized by augmenting the quantity of two-dimensional phases through surface composition engineering, without the need for excessive two-dimensional ligands that otherwise impede carrier transport. We demonstrate an open-circuit voltage of 1.373 V for 1.78 eV wide-bandgap perovskite solar cells, along with a high fill factor of 84.7%. This yields an open-circuit voltage of 2.21 V and a certified power-conversion efficiency of 29.1% for all-perovskite tandem solar cells, measured under the maximum power-point conditions. Substantial open-circuit voltage loss and inherent non-radiative recombination hinder efficiency improvements in wide-bandgap perovskite solar cells. Here the authors augment two-dimensional perovskite phases on the surface to promote (100) facet growth on three-dimensional perovskite facets, improving the open-circuit voltage and efficiency of the resulting wide-bandgap perovskite solar cells.
