A paradoxical defect: Hydrogen interstitial in 2D perovskite with in-gap states but inefficient nonradiative recombination

Hydrogen interstitials (Hi) in three-dimensional and all-inorganic perovskites have often been discussed as electronically active defects that can promote nonradiative recombination or exhibit unconventional defect dynamics. In contrast, we show that, in the two-dimensional perovskite (PhDMA)PbI4 [(PhDMA)=C6H4(CH2NH3)2...
