To overcome the challenges associated with poor temporal stability of perovskite solar cells,
methods are required that allow for fast iteration of fabrication and characterisation, such that …

The present thesis addressed the identification and characterization of spin states in
optoelectronic materials and devices using multiple spin-sensitive techniques. For this …
