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 ...

A study of the elemental reactions involved in the initiation of the polymerization of tetrahydrofuran induced by the photosensitization of a triphenylsulphonium salt by perylene

Journal of the Brazilian Chemical Society, 2003
The photopolymerization of THF was studied in the presence of a triphenylsulphonium salt and perylene. The mechanism involves an electron transfer from the excited singlet state of perylene to triphenylsulphonium ions, resulting in perylene cation ...
