Silicon Photonic Beam Steerer Based on Metalens Focal Plane Array

ABSTRACT Focal plane arrays (FPAs) promise robust solid‐state beam steering for LiDAR and free‐space optical communications. However, the need for external collimation lenses hinders chip‐scale compactness. Discrete switching between FPA elements further introduces blind spots an...

Mitigating Stress‐Induced Nonphotoactive Phase Transition Through Sodium Sulfonate Engineering for Stable and Efficient Perovskite Solar Cells

ABSTRACT Formamidinium lead triiodide (FAPbI 3 ) perovskite solar cells (PSCs) have attracted significant attention due to their outstanding optoelectronic properties. However, their long‐term stability remains limited by lattice strain‐induced transition from the photoactive α‐p...
