This is a comment on an article in Sustainable Energy & Fuels reporting time-resolved mass spectrometry (MS) of evolved gas species during photo-induced degradation of methylammonium lead iodide perovskite (MAPbI3 ).


The authors of the commented article released a response to these observations on February 1, 2019. This document has been updated including new comments to their response on March 13, 2019, see page 4. For the original version of this comment, please see version 1.
