Photonic nanovoids for tailored optoelectronic response in silicon solar cells

Responsive Materials, EarlyView.
Optoelectronic workflow followed by experimental validation, demonstrating state‐of‐the‐art efficiency gains. Abstract As crystalline silicon (c‐Si) solar cells become thinner to reduce cost and weight, the optical design principles that govern light trapping (LT) must evolve.

Broadband and Enhanced Second‐Harmonic Generation in Metallic 3R‐TaS2

Small, EarlyView.
A pronounced and robust SHG response has been observed in metallic 3R‐TaS2. It shows broadband SH conversion from 1020 nm to 1410 nm. Moreover, compared to the sapphire substrate, 3R‐TaS2 flakes with various thicknesses on the gold substrate showed different SHG enhancement; the enhancement factors range from 2.7 to 45.5.

Engineering and Tuning of High Quality Hexagonal Boron Nitride Nanophotonic Resonators

Small, EarlyView.
The manuscript explores nanofabrication protocols for photonic crystal cavities and microdisk resonators from hexagonal boron nitride. High Q cavities are fabricated and their resonances are controllably tuned. The work is important for future realization of quantum technologies with hexagonal boron nitride.

Machine Learning‐Guided Near‐Infrared Laser Processing for Precise Geometry Control in Microneedles with Downstream microLED‐Triggered Photothermal Functionality

Small, EarlyView.
Machine learning‐guided near‐infrared laser processing enables predictive fabrication of microneedles with application‐specific geometries. The optimized metal templates are translated into polymeric microneedles and integrated with a flexible microLED platform.

Multifunctional Cellulose Nanofiber Films With Embedded Highly Oriented MXene Flakes

Small, EarlyView.
The critical physical properties of freestanding micrometer‐thick films composed of layered cellulose nanofibers intercalated with Ti3C2Tx MXene nanosheets (CNF‐MXene) are investigated to find correlated co‐alignment of MXene flakes in the cellulose nanofiber matrix by vacuum‐assisted filtration.
