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…

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…
