Spectral‐Splitting Photovoltaic‐Thermal Solar Collectors Using Selective Hybrid Liquid‐Solid Optical Filters

Advanced Optical Materials, Volume 14, Issue 10, 13 March 2026.
A solar spectral‐splitting photovoltaic–thermal collector integrating a hybrid liquid‐solid optical filter is experimentally demonstrated. Selective optical filtering enables thermal–electrical decoupling, achieving elevated fluid temperatures while maintaining reduced PV operating temperatures.

Achieving Net‐Zero in the Electricity Sector in China by 2050 Considering Environmental and Economic Objectives

Advanced Sustainable Systems, Volume 10, Issue 3, March 2026.
China's pathways to net‐zero electricity by 2050 are evaluated using life cycle environmental and economic assessment across six scenarios. Results show that a renewables‐only grid offers the best overall environmental performance and lowest cost, but increases burdens on metal depletion, land use, and ecotoxicity.

Influence of thickness on crystallinity in wafer-scale GaTe nanolayers grown by molecular beam epitaxy

AIP Advances, 2017
We grew wafer-scale, uniform nanolayers of gallium telluride (GaTe) on gallium arsenide (GaAs) substrates using molecular beam epitaxy. These films initially formed in a hexagonal close-packed structure (h-GaTe), but monoclinic (m-GaTe) crystalline ...

Wafer Scale III‐Nitride Deep‐Ultraviolet Vertical‐Cavity Surface‐Emitting Lasers Featuring Nanometer‐Class Control of Cavity Length

Advanced Science, Volume 13, Issue 13, 3 March 2026.
A DUV‐VCSEL strategy featuring the nanometer‐class control of the cavity length is proposed in the DUV optoelectronic framework based on GaN templates. After the sapphire removal, a self‐terminated etching technology is developed, whereby the cavity length can be accurately determined by epitaxy instead of the fabrication process. As such, a record low
