Abstract

Abstract : Time‐resolved, grazing incidence small‐ and wide‐angle X‐ray scattering together with in situ UV‐Vis reflectance spectroscopy unveil the surface layering in the early stage of spin‐coating of a polymer‐fullerene mixture, which drives surface‐down local phase separation over the flow‐ to evaporation‐dominated stages of film formation for mutually confined and intercalated nanodomains of polymer crystallites and fullerene aggregates. This is reported by Chun‐Jen Su, U‐Ser Jeng, and co‐workers in article number1601842 .
