Ethylammonium iodide (EAI; CAS Number: 506-58-1) is an organic halide salt used in perovskite-based systems. Highly efficient perovskite solar cells are obtained by treating the photovoltaic devices with ethylammonium iodide used as surface passivation agent (Alharbi et al., 2019).
Greatcell Solar Materials' Ethylammonium iodide has a a purity level of >99% affording stable results and premium performance.
