Web1 apr. 2024 · After prolonged light soaking, however, negative ions, predominantly iodide interstitials drift to the spiro-MeOTAD/perovskite interface, significantly enhancing carrier recombination at that electrode. In contrast, light soaking had less effect at short-circuit because the electric field is invariant at short circuit. Web15 apr. 2024 · Employing first-principles approaches, we quantitatively show that the iodine interstitial is a dominant nonradiative recombination center in methylammonium-lead … Web26 okt. 2024 · Recently, the interaction between the iodide interstitials and injected holes at the interface between perovskite and electron transport layer (ETL), which triggers the degradation of PSCs under reverse bias, has been confirmed by drive-level capacitance profiling technique.
