Stability of Tin-Containing Hybrid Perovskites: The Thermal Decomposition of Formamidinium Tin Triiodide (FASnI₃) Investigated by Thermogravimetry and Effusion Techniques.

ABSTRACT: The gas-releasing thermal decomposition processes of formamidinium tin triiodide perovskite (CN₂H₅SnI₃, usually denoted as FASnI₃ or, briefly, FASI) were investigated in order to obtain information on the temperature at which decomposition begins and on the nature of the gas species emitted under heating. Results of thermogravimetry-differential thermal analysis (TG-DTA), thermogravimetry-differential scanning calorimetry (TG-DSC), and Knudsen effusion mass spectrometry (KEMS) experiments are presented. TG measurements showed that mass loss starts at temperatures much lower than those of the lead-based corresponding compound FAPbI₃, with incipient loss at temperatures as low as 423 K. Unlike FAPbI₃, practically no residue is
