Flexible transparent electronics require efficient power management without sacrificing visibility or mechanical compliance. This work presents a room‐temperature‐fabricated amorphous Ga2O3/NiO heterojunction diode on a flexible substrate that enables full‐wave rectification, UV photovoltaic energy harvesting, and self‐powered photodetection.

Beyond Radical Emitters: Hot‐Exciton Electroluminescence From Singlet Diradicaloids
The first hot‐exciton mechanism in a singlet diradicaloid is demonstrated in a polychlorinated Thiele hydrocarbon‐based organic light‐emitting transistor. Reverse intersystem crossing involving the T2 and bright singly excited states enables electroluminescence beyond the 25% spin‐statistical limit, leading to remarkable external quantum efficiency ...

Multiscale perspectives on how excess charges in soft lead halide perovskites induce operational instability in photovoltaic devices are presented. Localized carriers formed under thermodynamic non‐equilibrium states modify atomistic interactions and drive lattice distortions, accelerating device degradation.

A novel top‐to‐bottom film restructuring strategy is applied to perovskite films, taking advantage of high penetration of vapor‐phase ligand. A gradient‐distributed 2D perovskite structure is built up from top surface to film bulk, meanwhile, inhomogeneity at the buried interface is mitigated, which leads to high quality perovskite films with improved ...

Free Charge Generation in Organic Photoconversion Devices–the Impact of Electrostatic Potentials
Free charge generation in organic photovoltaic and photodetector devices typically requires an external driving force to separate bound excitons formed upon photoexcitation. This review details how electrostatic potentials, arising from molecular charge distributions in organic semiconductors, can impact interfacial energetic landscapes and promote ...

Transient electron spin resonance distinguishes interfacial charge‐transfer states from separated charges, revealing competing charge separation pathways in organic photovoltaic blends. The relative contributions of fast charge separation and a pathway mediated by spin‐polarized charge‐transfer states vary across different blends, with high‐efficiency ...
