The Role of Ultra‐Thin Buffer Layers for Achieving Ultra‐Low Dark Currents in Single‐Component Organic Photodetectors

Advanced Functional Materials, EarlyView.
Here, SubNc single‐component organic photodiodes (SC‐OPDs) are investigated, which achieve highly competitive performance metrics, including high EQE, ultra‐low JD, and high specific detectivity (D*). This study emphasizes the critical role of an organic buffer layer in studying the interface energetics and effects to achieve state‐of‐the‐art ...

Furan‐Substituted Phosphine‐Oxide as an Efficient Interfacial Modifier for Wide‐Bandgap Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
We report phosphine‐oxide interlayers for wide‐bandgap perovskite solar cells, in which tuned P = O Lewis basicity enables selective passivation of buried NiOx/perovskite interfaces and introduces interfacial dipoles that strengthen the built‐in field.

Polymer Network Modified Perovskite for High‐Performance Pure Blue Light‐Emitting Diodes

Advanced Functional Materials, EarlyView.
A polymer network of poly(4‐vinylphenol) (PVPh) is introduced to improve pure blue perovskite light‐emitting diodes. PVPh effectively passivates defects, enhances film morphology, reduces lattice strain, and suppresses ion migration. These effects lead to record device performance, achieving 9.82% external quantum efficiency and stable blue emission at
