With research in the field of PSCs booming, new materials (2D, 3D, QD PSC's etc.), architectures and compositional engineering are published frequently. Needless to say, such progress must go together with a suite of characterization techniques that should include synchrotrons, FEL's (Free Electron Lasers) along with laboratory-based tools. At present the application of synchrotron-based measurements for the characterization of PSCs can be considered to be in its infancy leaving a large variety of techniques and methods such as ptychography, multi-modal, in-situ and operando measurements unexplored.
