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…
Biorealistic Response in Optoelectrically-Driven Flexible Halide-Perovskite Single-Crystal Memristors
Ivan Matchenya, Anton Khanas, Roman Podgornyi +13
The transition to smart wearable and flexible optoelectronic devices communicating with each other and performing neuromorphic computing at the edge is a big goal in next-generatio…
Light-controlled multi-phase structuring of perovskite crystal enabled by thermoplasmonic metasurface
Sergey S. Kharintsev, Elina I. Battalova, Timur A. Mukhametzyanov +5
Halide perovskites belong to an important family of semiconducting materials with unique electronic properties that enable a myriad of applications, especially in photovoltaics and…
Multi-Stage Phase-Segregation of Mixed Halide Perovskites under Illumination: A Quantitative Comparison of Experimental Observations and Thermodynamic Models
Klara Suchan, Justus Just, Pascal Becker +5
Photo- and charge-carrier induced ion migration is a major challenge when utilizing metal halide perovskite semiconductors for optoelectronic applications. For mixed iodide/bromide…
Broad Distribution of Local I/Br Ratio in Illuminated Mixed Halide Perovskite Films Revealed by Correlative X-ray Diffraction and Photoluminescence
Klara Suchan, Justus Just, Pascal Becker +5
Photo-induced phase-segregation in mixed halide perovskite MAPb(BrxI1-x)3 is investigated in the full compositional range by correlative X-ray diffraction and photo-luminescence ex…
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…
