Abstract

We report herein the discovery of methylamine (CH 3 NH 2) induced defect‐healing (MIDH) of CH 3 NH 3 PbI 3 perovskite thin films based on their ultrafast (seconds), reversible chemical reaction with CH 3 NH 2 gas at room temperature. The key to this healing behavior is the formation and spreading of an intermediate CH 3 NH 3 PbI 3⋅x CH 3 NH 2 liquid phase during this unusual perovskite–gas interaction. We demonstrate the versatility and scalability of the MIDH process, and show dramatic enhancement in the performance of perovskite solar cells (PSCs) with MIDH. This study represents a new direction in the formation of defect‐free films of hybrid perovskites.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
