Amines are widely employed as additives for improving the performance of metal halide perovskite optoelectronic devices. However, amines are well-known for their high chemical reactivity, the impact of which has yet to receive enough attention from the perovskite light-emitting diode community. Here, by investigating an unusual positive aging effect of CH<sub>3</sub>NH<sub>3</sub>I/CsI/PbI<sub>2</sub> precursor solutions as an example, we reveal that amines gradually undergo N-formylation in per ...[more]
