CdCl2 Treatment for Cu2ZnSn(S,Se)4: A Method to Enhance the Solar Cell Performance

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
We present, for the first time, two alternative CdCl2 treatments applied to solution‐processed kesterite (CZTSSe) absorbers: pre‐selenization and post‐selenization. Carrier concentration is consistently increased by either route, whereas the band gap decreases with pre‐selenization but remains nearly constant with post‐selenization; enhanced defect ...

End‐to‐End Portfolio Optimization with Hybrid Quantum Annealing

open access: yesAdvanced Quantum Technologies, EarlyView.
This works presents a hybrid quantum‐classical framework for portfolio optimization that combines quantum assisted asset selection and rebalancing with classical weight allocation. The approach processes real market data, embeds it into Quadratic Unconstrained Binary Optimization formulations, and evaluates performance within a unified workflow ...

4D printing of fast‐responsive liquid crystalline elastomers for light‐driven actuators

open access: yesResponsive Materials, EarlyView.
Combining 3D printing with responsive materials, known as 4D printing, enables the fabrication of smart structures with programmable actuation. This study presents a photoresponsive LCE ink for DIW, achieving millisecond‐scale activation under blue light.

Ultrabroadband Spacetime Nanoscopy of Terahertz Polaritons in a van der Waals Cavity

open access: yesSmall, EarlyView.
This work introduces SYnchrotron SpaceTimE Mapping (SYSTEM), which captures real‐time evolution of polariton wave packets with ∼10 nm spatial and sub‐100 fs temporal resolution across an ultrabroadband 5 to 50 THz range. Here, SYSTEM directly visualizes the creation, interference, and decay of multiple high‐quality Fabry‐Pérot phonon polariton cavity ...
