It reveals that the light soaking at 60 °C induces the decomposition of MAPbBr3 perovskite accompanied with the decay of organic cation and the release of a PbBr2 phase as a degradation product whereas the photochemical degradation completely disappears while the aging temperature is decreased to 10 °C.hybrid perovskites | stability | temperature-dependent degradation | XPS[SDGs]SDG7journal article10.3390/coatings120810662-s2.0-85137596043WOS:000847181100001https://api.elsevier.com/content/abstract/scopus_id/85137596043
