Wavelength and Full‐Polarization Encrypted Orbital Angular Momentum Meta‐Holography

Laser &Photonics Reviews, EarlyView.
By multiplexing three independent degrees of freedom of light, a single‐layer geometric‐phase metasurface encrypts 24 distinct holographic images across 3 wavelengths, 12 pairs of orthogonal polarizations, and 4 OAM channels, taking advantage of axial chromatic dispersion to reconstruct the color images at the same plane. ABSTRACT Multiplexing multiple

Indium‐Free Silicon Heterojunction Solar Cells: Achieving High Conductivity With Magnetron‐Sputtered SnO2

Progress in Photovoltaics: Research and Applications, EarlyView.
Amorphous SnO2 films with low resistivity (~1.2 × 10−3 Ωcm) were realized by low‐temperature magnetron sputtering through control of O2 flow ratio, substrate temperature, and H incorporation. Si heterojunction solar cells incorporating these films achieved a conversion efficiency of 21.1%, approaching that of cells based on MS‐ITO and RPD‐SnO2 ...

Ultrathin Freestanding BiFeO3 Membranes Grown by Pulsed Laser Deposition

Small, EarlyView.
Ultrathin freestanding BiFeO3 membranes down to five‐unit cells are realized by pulsed laser deposition using a water‐soluble Sr3Al2O6 sacrificial layer. Strontium diffusion is revealed to drive the spontaneous formation of an Aurivillius‐like phase, while ultrathin SrRuO3 interlayers suppress interfacial intermixing, preserve polar tetragonality, and ...

Phase Engineering of Plasma‐Enhanced Atomic Layer Deposited Molybdenum Disulfide Using High Accuracy Direct Writing With Focused Li+ and Ga+ Ion Beams and Ultrashort Pulse Laser

Small, EarlyView.
In the context of phase heterostructures on two‐dimensional materials, a high‐precision direct writing approach is employed. This involves using a focused ion beam to transform molybdenum disulfide to the metallic 1T phase, followed by retransformation via ultrashort pulse laser processing.

Benefit Mechanism and Enhancement Strategy of High‐Proportion Building Photovoltaic Systems Under Carbon Reduction Constraints

IET Smart Energy Systems, EarlyView.
A benefit evaluation framework for high‐proportion building photovoltaic systems was established considering carbon reduction constraints and grid absorption costs. The study reveals the intrinsic contradiction between system‐level benefits and PV utilisation benefits, and proposes a dual‐driven optimisation pathway of effective generation and ...
