Imidazolium Iodide


Imidazolium iodide (IAI; CAS Number: 68007-08-9) is an organic ammonium halide salt used as a perovskite precursor in the preparation of perovskite-based opto-electronic devices. The addition of Imidazolium iodide as a surface passivation agent on mixed-cation and mixed-halide perovskite films considerably increased the perovskite solar cell performance and improved the operational stability of the resulting device (Alharbi et al., 2019).

Greatcell Solar Materials’ Imidazolium iodide is of the highest purity affording consistent results and superior performance.
