Unraveling the Roles of Shallow, Deep and Auger Trapping in Charge Carrier Recombination in Triple-Cation Perovskites
Jitendra Kumar, Thomas Kirchartz, Alexandr Marunchenko +7
Understanding charge-carrier recombination in metal halide perovskites is essential for accurately identifying the factors limiting solar cell efficiency, yet it remains challengin…
Photoluminescence Mapping over Laser Pulse Fluence and Repetition Rate as a Fingerprint of Charge and Defect Dynamics in Perovskites
Shraddha M Rao, Alexander Kiligaridis, Aymen Yangui +3
Defects in metal halide perovskites (MHP) are photosensitive, making the observer effect unavoidable when laser spectroscopy methods are applied. Photoluminescence (PL) bleaching a…
Remarkable performance recovery in highly defective perovskite solar cells by photo-oxidation
Katelyn P. Goetz, Fabian T. F. Thome, Qingzhi An +8
Exposure to environmental factors is generally expected to cause degradation in perovskite films and solar cells. Herein, we show that films with certain defect profiles can displa…
Memlumor: a luminescent memory device for photonic neuromorphic computing
Alexandr Marunchenko, Jitendra Kumar, Alexander Kiligaridis +10
Neuromorphic computing promises to transform the current paradigm of traditional computing towards Non-Von Neumann dynamic energy-efficient problem solving. Thus, dynamic memory de…
Are Shockley-Read-Hall and ABC models valid for lead halide perovskites?
Alexander Kiligaridis, Pavel Frantsuzov, Aymen Yangui +5
Metal halide perovskites are an important class of emerging semiconductors. Their charge dynamics is poorly understood due to limited knowledge of defect physics and charge recombi…
