a QFLS values for the stack of ITO/NiOx/MeO-2PACz/perovskite/C60 at various C60 deposition cycles, together with without C60 stack. b PDS absorption spectra of the quartz/perovskite/ C60 stacks, and c its phase shift compared to excitation. d Electron mobility values of the C60 layers at 1st and 8th cycles measured via FETs. e UPS spectra of the C60 thin films on c-Si wafer showing the distribution of the energy states close to the HOMO level. f MALDI-TOF analysis on thin films produced from both fresh and thermally cycled powders. To perform this analysis, the films were deposited on glass substrates and subsequently scratched to collect the resulting powder, which was then utilized for the MALDI-TOF analysis.
