Self‐Reinforcing Degradation of Solution‐Processed Small‐Molecule OLEDs: Excited‐States and Molecular Interactions as Key Triggers

open access: yesAdvanced Functional Materials, EarlyView.
Self‐reinforcing degradation in solution‐processed small‐molecule organic light‐emitting diodes (OLEDs) arises from charge accumulation and exciton‐polaron interactions, leading to molecular aggregation and efficiency loss. This study uncovers the fundamental mechanisms behind this degradation and introduces strategic material engineering approaches ...

Understanding Postdeposition Treatments of Hole‐Transporting Self‐Assembling Molecules for Perovskite/Silicon Tandem Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
The influence of postdeposition treatments on the formation of self‐assembling (mono)layers commonly utilized as hole transport layers in perovskite‐based solar cells is thoroughly investigated. The implementation of a washing step and an annealing step at temperatures exceeding the current literature standards leads to an enhanced layer quality and ...
