Iodide interstitials
Web12 apr. 2024 · In specific, previous research revealed that light-induced performance degradation of PSCs mainly arose from the generation of iodide interstitials (I I − and I I +) at the perovskite/charge transport layer interfaces; where electric-bias induced degradation also originated from the interaction between I I − and hole carriers transferred from ETL. Web10 nov. 2024 · Meggiolaro et al. (2024) suggested that oxygen as a Lewis acid is capable of passivating deep hole traps associated with iodide interstitials, and other defects, such as lead interstitials and ...

Web10 nov. 2024 · On the basis of state-of-the-art density functional theory modeling, we propose a mechanism whereby oxygen effectively inactivates deep hole traps associated with iodide interstitials by forming moderately stable oxidized products. The small energy gain associated with trap passivation is in agreement with the reversibility of the process. Web24 mei 2016 · For example, the formation energy of iodide interstitials in iodide-rich conditions is also ∼ 0.2 eV, suggesting that the activation energy we extract here could be related to the interstitial ...
