Molecular Coordination–Driven Photothermally Stable FACs‐based Perovskite Solar Cells with Efficiency Over 25% via Dicarbonyl‐Functionalized Thienoacene Small Molecule

ABSTRACT The practical deployment of perovskite solar cells (PSCs) is critically hindered by their susceptibility to moisture, oxygen, and thermal degradation, particularly under high‐temperature and high‐humidity conditions. Herein, we design and synthesize a dicarbonyl‐function...

Direct Silicon/Perovskite Heterojunction Solar Cells Enabled by Interfacial Energetics and Charge-Selective Contact Engineering

Abstract Single-junction crystalline silicon (Si) and perovskite solar cells are approaching their fundamental efficiency limits, while the prevailing Si/perovskite tandem architecture requires complex sub-cell interconnection and current matching. Here, we developed a Si/perovsk...

Multifunctional CuSbS2 Nanocrystals as an Integrated Flexocatalytic–Photocatalytic–Nanozymatic Platform for Antibacterial Therapy

Abstract Ultrasound-enabled catalytic strategies offer a non-invasive route for antibacterial therapy but are typically limited to non-centrosymmetric piezoelectric materials. Herein, we developed ultrasound-assisted flexocatalysis as a symmetry-independent approach for reactive...
