Advanced Science, EarlyView.In situ grazing‐incidence X‐ray scattering and in situ UV–vis spectroscopy are being used for the first time to reveal the morphological evolution of all‐polymer solar cell (APSCs) blends during solvent vapor annealing (SVA). SVA strongly influences the recrystallization and reordering behavior of APSCs blends, successfully establishing the ...
