Strategy for One‐Step Optimization of Metal Oxide Passivating Contact Materials for Si Heterojunction Solar Cells through Growth Angle Variation

Small, EarlyView.
A one‐step oblique angle reactive sputtering approach enables simultaneous tuning of bulk and interfacial stoichiometry in a metal oxide/ silicon heterojunction. In case of vanadium oxides, growth angle variation controls the formation of stoichiometric SiO2, ternary SiOx(V) interlayer, and phase purity of vanadium oxide, considerably simplifying the ...

Highly Selective Photocatalytic Degradation of Organic Pollutants by ZnO@C Core–Shell Nanoparticles Via Superoxide Radical Pathway

Small, EarlyView.
This study investigates a novel two‐step synthesis of ZnO@C nanoparticles (NPs), featuring enhanced photocatalytic dye degradation via selective superoxide (O2•−) radical generation under visible light. The precisely engineered carbon shell uniquely improves light–matter interaction and visible‐light absorption, as well as facilitates efficient charge ...

On‐Tip Polymerization Method for Multimodal Characterization of Nanoparticles with Electron/Ion Imaging and Atom Probe Tomography

Small Methods, EarlyView.
This study presents an on‐tip polymerization method that employs a needle substrate with a designed through‐microchannel (“needle‐eye”) to retain a picoliter‐scale solution of nanoparticles. Using a resin precursor as the solution, polymerization is carried out in situ at the needle tip.

Clouds dissipate quickly during solar eclipses as the land surface cools

Communications Earth & Environment
Clouds affected by solar eclipses could influence the reflection of sunlight back into space and might change local precipitation patterns. Satellite cloud retrievals have so far not taken into account the lunar shadow, hindering a reliable spaceborne ...

Impact of Halide Alloying on the Phase Segregation of Mixed‐Halide Perovskites

Small Structures, EarlyView.
Halide segregation impedes the development of stable mid‐ and wide‐gap perovskite‐based multijunction solar cells. Here, X‐ray diffraction is utilized to unravel the impact of changing bromide fraction on halide segregation in the prototypical CH3NH3Pb(I1−xBrx)3 system across a finely tuned compositional space. Segregation rates and extents are mapped,
