Quantum Efficiency Enhancement of Lead-Halide Perovskite Nanocrystal LEDs by Organic Lithium Salt Treatment
Tassilo Naujoks, Roshini Jayabalan, Christopher Kirsch +9
Surface-defect passivation is key to achieving high photoluminescence quantum yield in lead halide perovskite nanocrystals. However, in perovskite light-emitting diodes these surfa…
Improvement of Photophysical Properties of CsPbBr and Mn:CsPb(Br,Cl) Perovskite Nanocrystals by Sr Doping and Their Application in White-LEDs
Hurriyet Yuce, Mukunda Mandal, Yenal Yalcinkaya +2
All-inorganic lead halide perovskite nanocrystals (NCs) show potential in optoelectronic devices, though their stability and efficiency have yet to improve. In this work, we explor…
Chemical design rules for non-fullerene acceptors in organic solar cells
A. Markina, K. -H. Lin, W. Liu +14
Efficiencies of organic solar cells have practically doubled since the development of non-fullerene acceptors (NFAs). However, generic chemical design rules for donor-NFA combinati…
Charge Photogeneration in Non-Fullerene Organic Solar Cells: Influence of Excess Energy and Electrostatic Interactions
Maria Saladina, Pablo Simón Marqués, Anastasia Markina +11
In organic solar cells, photogenerated singlet excitons form charge transfer (CT) complexes, which subsequently split into free charge carriers. Here, we consider the contributions…
Spatially resolved fluorescence of caesium lead halide perovskite supercrystals reveals quasi-atomic behavior of nanocrystals
Dmitry Lapkin, Christopher Kirsch, Jonas Hiller +16
We correlate spatially resolved fluorescence (-lifetime) measurements with X-ray nanodiffraction to reveal surface defects in supercrystals of self-assembled caesium lead halide pe…
Porphyrin-functionalization of CsPbBrI/SiO core-shell nanocrystals enhances the stability and efficiency in electroluminescent devices
Jan Wahl, Manuel Engelmayer, Mukunda Mandal +7
Surface ligand exchange on all-inorganic perovskite nanocrystals of composition CsPbBrI reveals improved optoelectronic properties due to strong interactions of the nanocryst…
