We report positive and negative ion time-of-flight secondary ion mass spectrometry (ToF-SIMS) spectra of metal-halide perovskite (MHP) films used for photovoltaic applications. This ToF-SIMS spectral library is of importance because it identifies the major peaks in most MHP films from organic [formamidinium (FA+)] and inorganic (Cs+) cations and anions (I and Br).
