High‐Resolution Multispectral Photovoltaic Imagers from Visible to Short‐Wave Infrared

open access: yesAdvanced Science, EarlyView.
We demonstrate a monolithic quad‐spectral imager that seamlessly integrates visible and short‐wave infrared detection on a single chip. Through direct photopatterning of an all‐polymer bulk heterojunction and colloidal quantum dots, the device achieves high‐resolution (640 × 512) imaging across 350–2400 nm, enabling multispectral capture for ...

Molecular Cluster‐Controlled Quasi‐Epitaxial CZTSSe/CdS Heterojunction Enables 12.3% Efficiency of Flexible Solar Cells

open access: yesAdvanced Science, EarlyView.
By controlling the synthesis of CdS molecular clusters, a quasi‐epitaxial heterojunction is directly constructed during chemical bath deposition, enabling flexible kesterite solar cells to achieve an efficiency of 12.3%. Abstract Flexible Cu2ZnSn(S,Se)4 (CZTSSe) solar cells have garnered significant attention in photovoltaics.

Ultrafast Multilevel Switching and Synaptic Behavior in a Planar Quantum Topological Memristor

open access: yesAdvanced Science, EarlyView.
Dry‐transferred Bi2Te3 layers enable a planar quantum topological memristor framework. In‐plane topological surface states facilitate ultrafast & low‐power operations. Coexisting analog and digital modes support current‐controlled multilevel states. PQTM exhibits 105 s retention, 103 cycles endurance, and reproducibility across 24 devices.
