Mitigating Mobile‐Ion‐Induced Instabilities and Performance Losses in 2D Passivated Perovskite Solar Cells

open access: yesAdvanced Materials, EarlyView.
This study addresses the challenges of mobile‐ion‐induced instability in perovskite solar cells. Introducing bilayer passivation with ammonium salts (EDAI₂/PEAI and ABS/PEAI) significantly reduces ion density and improves device stability. The approach mitigates the detrimental effects of PEAI‐induced ionic losses, enhancing both performance and ...

On‐Chip Active Non‐Reciprocal Topological Photonics

open access: yesAdvanced Materials, EarlyView.
An ultra‐compact and efficient on‐chip isolator is experimentally demonstrated by integrating magneto‐optical InSb onto a terahertz silicon topological chip. The simultaneous breaking of spatial and temporal reversal symmetries forms a valley‐conserved non‐reciprocal waveguide mode, enabling a compact cavity size of 6.4 × 2.5λ2 and a low insertion loss
