Peripherally Fluorinated Tetraphenylethene: New Electron Extraction Interlayers for n‐i‐p Perovskite Solar Cells

Advanced Energy Materials, EarlyView.
Fluorinated tetraphenylethene (TPE) derivatives were developed as interfacial layers for perovskite solar cells. The optimized TFP‐TPE enhances interfacial compatibility, suppresses molecular aggregation, and improves charge extraction. Devices incorporating TFP‐TPE achieved a record efficiency of 25.29% and outstanding stability under humidity and ...

Astrocyte-Mediated Neuronal Synchronization Properties Revealed by False Gliotransmitter Release [PDF]

, 2017
Astrocytes spontaneously release glutamate (Glut) as a gliotransmitter (GT), resulting in the generation of extrasynaptic NMDAR-mediated slow inward currents (SICs) in neighboring neurons, which can increase local neuronal excitability. However, there is

Defect engineering for highly efficient and stable perovskite top cells for Si tandems

Bulletin of the Korean Chemical Society, EarlyView.
Defect passivation in wide‐bandgap perovskites is essential for enabling high‐efficiency and stable perovskite/Si tandem solar cells. Bulk, surface, and buried‐interface passivation strategies focus on suppressing nonradiative recombination, ion migration, and halide segregation, thereby clarifying critical design principles for next‐generation tandem ...
