In this dissertation, the opportunities offered by solid-state NMR (SSNMR) spectroscopy to study perovskite materials for photovoltaic application are discussed and analysed. The attention will be focused on the possibility that information obtained thanks to SSNMR could provide crucial knowledge on the link between structural and dynamic properties, on a nano- and microscopic level, and photovoltaic efficiency.
Recent scientific literature about NMR studies of perovskites systems will be analysed and discussed to enlighten the materials features that can be probed via SSNMR (compositional variations and incorporation of ions into the lattice, local dynamics and diffusion, degradation mechanisms and stability) and to suggest possible directions for future studies.
