Antimony oxide buffer layer for single- and double-junction perovskite-based solar cells
Abstract Atomic layer-deposited tin oxide serves as an effective buffer layer in perovskite/silicon tandem solar cells due to its efficient charge extraction and sputtering tolerance. Nevertheless, its unavoidable chemical erosion effect of atomic layer-deposited tin oxide on perovskite requires thicker fullerene charge transport layers, leading to increased parasitic optical absorption. Herein, we firstly integrated thermal evaporated antimony oxide into solar cells to effectively replace atomic layer-deposited tin oxide, enabling a thinner fullerene to minimize optical losses and prevent damage to the perovskite. The unique amorphous-nanocrystalline structure of, antimony oxide facilitates ultrafast carrier transport via its embedded nanocrystalline network. The antimony oxide-based tandem solar cells demonstrated a significant improvement in power conversion efficiency compared to tin oxide-based devices, primarily due to an enhanced short-circuit current density of approximately 1 mA/cm² in the perovskite top cell. Remarkably, even at 64.64 cm 2 scale, the antimony oxide-based encapsulated large-area tandem solar cell retains an efficiency of 28.16% (with a certified value of 27.70%), attesting the scalability of this approach.

Electron and spin dynamics in a single quantum emitter
Abstract The Auger–Meitner effect is a fundamental electron–electron scattering process that impacts the electron and spin dynamics in semiconductor quantum emitters, such as colloidal nanocrystals and quantum dots. Here, we present an experimental study of the magnetic-field dependence of Auger–Meitner recombination and spin-related scattering processes in a single self-assembled InAs quantum dot. Using two-color, time-resolved resonance fluorescence with spectrally separated detection of both exciton and trion transitions, we extract the Auger–Meitner recombination rate, the electron spin-flip relaxation rate, and the spin-flip Raman scattering rate over a broad magnetic-field range from $$B = 0$$ B = 0 to $$8\,\textrm{T}$$ 8 T . We observe a suppression of the Auger–Meitner recombination rate for magnetic fields above $$B = 4\,\textrm{T}$$ B = 4 T . In contrast, the electron spin-flip relaxation rate increases strongly for fields above $$B = 3\,\textrm{T}$$ B = 3 T and decreases at lower magnetic fields, while the spin-flip Raman scattering rate remains nearly constant. Our results demonstrate that two-color, time-resolved resonance fluorescence enables access to all relevant microscopic rates for optimizing quantum dots as building blocks for future quantum technologies.

Rhizobacteria opportunistically boost colonization and impair plant fitness by degrading plant-derived coumarins under iron deficiency
Abstract Plants recruit root-associated bacterial assemblies primarily through the secretion of specialized metabolites, and the resultant rhizospheric microbiota is empirically considered beneficial. However, detrimental effects on plants arising from bacterial colonization that exploits plant-derived metabolites are rarely documented. Here, we demonstrate that the rhizosphere-derived Pseudomonas sp. strain NyZ480 exhibits a versatile capacity to effectively degrade and utilize simple coumarins — a class of root exudates essential for plant iron acquisition and pathogen defense. This robust catabolic capability is mediated by conserved genetic determinants in NyZ480. In particular, redundant degradation-initiating xenA genes confer NyZ480 not only growth using simple coumarins but also resistance to these antimicrobial metabolites. Consequently, NyZ480 significantly colonizes iron-stressed, coumarin-secreting Arabidopsis roots, trapping plants in perpetual iron scarcity and progressively compromising iron acquisition and overall fitness. Bioinformatic analyses indicate that xenA homologs are prevalent and redundant in environmental bacteria. Thus, we reveal a rhizospheric phenomenon where microorganisms opportunistically utilize and detoxify host-secreted specialized metabolites under stress conditions, enhancing colonization and impairing plant fitness.
