Integrated Optoelectronic Model to Predict the External Quantum Efficiency of Single‐Layer TADF Organic Light‐Emitting Diodes

open access: yesAdvanced Electronic Materials, EarlyView.
An experimentally validated optoelectronic device model is presented to describe the efficiency and roll‐off behavior of single‐layer TADF OLEDs. By coupling charge transport, exciton dynamics, and optical outcoupling, the model reproduces the External Quantum Efficiency (EQE) across different emission layer thicknesses and temperatures, offering ...

Solution Processed Polymer Source‐Gated Transistors for Zero‐Power Photosensing

open access: yesAdvanced Electronic Materials, EarlyView.
This study demonstrates the first solution‐processed bulk heterojunction organic source‐gated transistors (OSGTs) and photo‐OSGTs fabricated using DPP‐DTT: PCBM. Copper‐electrode OSGTs show deep off‐state at zero gate‐source voltage, channel length‐independent on‐state current, and low voltage saturation (γ = 0.22).

Role of Rare‐Earth Lanthanum Doping on Electrical Performance and Stability of Atomic Layer Deposition Processed Indium Oxide Thin‐Film Transistors

open access: yesAdvanced Electronic Materials, EarlyView.
The work demonstrates La doping in In2O3 via ALD super‐cycles. The strong La─O bond suppresses oxygen vacancies, resulting in a decrease in mobility and a positive shift in threshold voltage. The effective suppression of VO decreases oxygen‐related defects under gate bias, leading to exceptional negative bias stability.

Selective Ion‐Blocking Strategy for Stabilizing Perovskite Tandem Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
A selective ion‐blocking Li─T interlayer is introduced at LiF‐passivated perovskite interfaces to suppress fluorine diffusion while preserving the beneficial interfacial passivation of LiF. This ion‐blocking strategy markedly improves the long‐term operational stability of both single‐junction and monolithic all‐perovskite tandem cells under continuous

Selective Charge Extraction Allows Fast Photomultiplication and Imaging in Rigid and Ultra‐Flexible SWIR Organic Photodiodes

open access: yesAdvanced Energy Materials, EarlyView.
SWIR donor polymer TQ‐3T allows photomultiplication in OPD in 1:1 ratio with NFA Y6, achieving EQEs > 1100% at ‐10 V. Microseconds response times are retained, amongst the lowest for photomultiplication. As proof of concept, we demonstrate ultrathin and flexible PM‐OPDs based on our TQ‐3T:Y6 as a flexible pulse oximeter as well as a conformable image ...
