Perovskite Precursor Materials
When solution processing perovskite films, perovskite precursor materials are dissolved into a perovskite ink. These inks often consist of an organic salt (MAI, FAI, etc) combined with an inorganic salt (usually lead iodide or lead bromide) in a polar solvent.
Using quality perovskite materials is the key to achieving high efficiency perovskite devices. The type and stoichiometry of perovskite precursor materials will significantly affect the application, efficiency and stability of your perovskite
