Phenethylammonium iodide

• 
  Phenethylammonium iodide (PEAI; CAS Number: 151059-43-7) is an effective passivation agent used in the preparation of perovskite-based opto-electronic systems (Li et al., 2020). The cation PEA+ is a common organic Spacer used to form quasi-2D perovskites resulting in efficient solar cells exhibiting an improved tolerance to moisture provided by the bulky hydrophobic aromatic ring (Ye et al., 2021). The introduction of Phenethylammonium iodide into the precursor solution consisting of methylammonium iodide (MAI) and lead iodide (PbI2) to form a perovskite LED led to a ~50-fold enhancement in the quantum efficiency of the resulting device (Lee et al., 2021).
