Deskripsi
Charge dynamics in perovskite is not well-understood, limited by the knowledge of defect physics and charge recombination mechanism, yet the ABC and SRH models are widely used. Here, the authors introduce advanced PLQY mapping as function of excitation pulse energy and repetition frequency to examine the validity of these models.
