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

Advanced Materials Interfaces, EarlyView.The research focuses on the interaction between the magnetic DyPc2 molecules and the superconducting Pb(111) surface. A complex quantum spin system is observed in both DyPc2 molecules embedded in the self‐assembled monolayer and those scattered atop it, where Kondo screening and superconducting pairing coexist and compete.

Advanced Materials Interfaces, EarlyView.A novel and efficient method is explored to synthesize 1D single‐crystal sub‐stoichiometric WnO3n‐2 (n = 25) nanowire bundles. The approach utilizes selective low‐energy He+ ion irradiation (27 eV) on Mo‐Ni doped WOx surface, achieving efficient catalyst‐free self‐organized growth of high aspect ratio nanowires at the temperature of 700 °C.
