All‐Solution‐Processed Perovskite Light‐Emitting Transistors Enabled by a Fully Organic Architecture

open access: yesAdvanced Electronic Materials, EarlyView.
Fully solution‐processed light‐emitting transistors based on CsPbBr3 perovskite nanocrystals (Pe‐LETs) are demonstrated using an all‐organic platform. By optimizing film formation and device integration, the Pe‐LETs achieve bright green emission with excellent color purity and a peak external quantum efficiency of 4.17 × 10−3 %, marking a step forward ...

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 ...

Aging and Electrical Stability of DNTT Honey‐Gated OFETs

open access: yesAdvanced Electronic Materials, EarlyView.
DNTT honey‐gated organic transistors were fabricated and evaluated to assess short‐ and long‐term stability under electrical stress and aging. Short‐term transfer measurements (five days, 40 sweeps/day) showed minimal parameter shift, while extended measurements revealed gradual degradation over weeks.

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

open access: yesAdvanced 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 ...

Alcohol‐Adduct Mediated Precursor Stabilization Strategies for Conformal SnO2 Layers in Highly Efficient and Stable Perovskite Solar Modules

open access: yesAdvanced Energy Materials, EarlyView.
An alcohol‐adduct‐mediated strategy is employed to stabilize tin isopropoxide for the formation of a homogeneous double electron transport layer (ETL) incorporating SnO2 nanoparticles (NPs). This double‐ETL exhibits improved optical and charge‐transport properties due to reduced defect density and better energy level alignment, resulting in high ...

Lattice Coherency‐Driven (111)‐Oriented Wide Bandgap Perovskite Films

open access: yesAdvanced Energy Materials, EarlyView.
Methylammonium lead chloride (MAPbCl3)‐derived seed templates regulate wide‐bandgap perovskite crystallization through coupled thermodynamic and kinetic effects. Lattice‐coherent templating lowers the energy cost for (111) epilayer growth, while growth retardation controls crystallization kinetics, ultimately producing highly crystalline face‐up (111 ...

Multiscale Perspectives on Perovskite Instability: From Atomistic Deformation to Device Degradation in Perovskite Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
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.
