Аннотация: X-ray photoelectron spectroscopy (XPS) was used to examine the MAPbI₃/Si interface (MA = methylammonium) before and after 45 days of exposure to light, heat stress at 85 °C or 50% relative humidity (RH). From the survey XPS spectra it follows that under these external influences, changes in the I/Pb ratio, indicating the presence of the PbI₂ phase as a degradation product, do not go beyond 12%. These results were confirmed by measurements of high-resolution XPS spectra in the energy ranges of Pb 4f, I 3d and valence band signals, which do not show significant high-energy shifts towards the energy position of the PbI₂ reference spectra.

Ключевые слова: XPS, hybrid perovskites, methylammonium lead halides, stability, interface, UV irradiation, thermal degradation, photochemical degradation.
