Proton Irradiation Tolerance of Fully Printed Self‐Powered Carbon‐Electrode Perovskite Photodetectors

Advanced Electronic Materials, EarlyView.
Proton irradiation effects on fully printed carbon‐electrode perovskite photodiodes are systematically examined. Devices exposed to 0.5 MeV protons retain structural integrity while exhibiting defect‐induced changes in local coordination and recombination dynamics.

A Blue Emissive Heavy Atom‐Free Multiresonant Thermally Activated Delayed Fluorescent Emitter Shows Ultra‐Fast Reverse Intersystem Crossing

Angewandte Chemie, EarlyView.
The extended π‐system and low‐lying n‐π∗ transition endow DDOBDiKTa with a synergistic combination of strong spin‐orbit coupling, small reorganization energy and small ΔEST, enabling this blue boron‐nitrogen‐carbonyl hybrid emitter to achieve a fast kRISC of 6.34 × 106 s−1 together with OLEDs showing small efficiency roll‐off, with EQEmax/EQE10000 of ...

Dry‑Contact Trimming for All‑Perovskite Tandem Solar Cells via Solid‑Solution Homogenization

Advanced Energy Materials, EarlyView.
Narrow‐bandgap Sn–Pb perovskites are promising bottom absorbers for all‐perovskite tandems but suffer from Sn‐rich surfaces and depth‐dependent lattice/compositional inhomogeneity. Layered‐perovskite‐assisted dry‐contact trimming removes Sn‐rich surface species and reconfigures the Sn–Pb absorber, enabling efficient charge collection, reduced voltage ...
