4‐methoxyphenethylammonium (MeO‐PEA) is a Spacer cation used in the preparation of quasi‐2D perovskite solar cells (Fu et al., 2019). The latter can be prepared from the perovskite precursor 4-Methoxyphenethylammonium iodide (4MeO-PEAI) that Borun New Material - ChemBorun manufactures at a purity level >99%.
