Temperature‐Dependent Zinc Oxide Cathodoluminescence: Toward Compact Wavelength‐Tunable Solid‐State Photoionization Sources

Advanced Optical Materials, EarlyView.
A proof‐of‐concept of a thermally‐tunable cathodoluminescence‐based light source is demonstrated using a wide‐bandgap z‐cut ZnO crystal as anode, resulting in the ultraviolet (UV) emission peak shifting from 398 nm to ~409 nm (3.115‐3.032 eV). Our results establish the feasibility of a compact, field‐deployable UV source with potential for gas sensing ...

Selective Crystal Growth and Optical Responses of 2H and 3R Polytypes in van der Waals Polar Insulator α‐In2Se3

Advanced Optical Materials, EarlyView.
Selective growth protocols are established to obtain high‐quality bulk single crystals of the 2H and 3R polytypes of the vdW polar insulator α‐In2Se3, together with rapid, non‐destructive phase‐identification methods. Combined optical transmission and absolute reflectivity measurements, supported by DFT calculations, reveal distinct polytype‐dependent ...

Engineering of Double Absorber Organic‐Perovskite Solar Cells for >34% Efficiency with V2O5 as Back Surface Field Layer

Advanced Photonics Research, EarlyView.
This study investigates high‐efficiency double perovskite active layer (DPAL) structures using MAPbI3 and MASnI3 to surpass the Shockley‐Queisser limit in single‐junction perovskite solar cells. SCAPS‐1D simulations show that the V2O5‐assisted DPAL device achieves 34.14% power conversion efficiency with improved JSC, VOC, and FF.
