Recent Advances in Wide‐Bandgap Perovskite Solar Cells
Advanced Materials, EarlyView.Ubiquitous defects predominately account for photo‐instability and open‐circuit voltage losses in wide‐bandgap perovskite solar cells (WBG PSCs). This review comprehensively presents the underlying impact mechanisms, summarizes the advanced optimization strategies across various functional layers and their interfaces to develop efficient and stable WBG

A Neuransistor with Excitatory and Inhibitory Neuronal Behaviors for Liquid State Machine
Advanced Materials, EarlyView.The neuransistor integrates hybrid excitatory and inhibitory dynamics, enabling liquid state machine implementation. It operates via charge trapping in a two‐dimensional electron electron gas (2DEG)/TiO2−x structure and features a three‐terminal design for efficient masking functionality. Simulations demonstrate its effectiveness in predicting temporal
