We applied CLIM to wide-field fluorescence microscopy videos of methylammonium lead triiodide (MAPbI3) thin films. Notably, the CLIM clusters precisely matched the grain microstructure observed in SEM imaging. PL fluctuations analysis of individual grains reveal a single type of trap being responsible for the fluctuations and shows dependence on the film morphology. Finally, we demonstrated that CLIM effectively images and tracks local structure and photoluminescence under varied operational conditions in a photovoltaic device. CLIM's enhanced imaging contrast opens new possibilities in optical microscopy for functional imaging of materials and in-operando device examination.
