In article no. 1800114 , Tao Wang and co‐workers investigate the three‐dimensional morphology of PBDB‐T:IT‐M non‐fullerene solar cells. A PBDB‐T‐rich layer forms on the blend surface, and will either retain or disappear upon thermal annealing depending on the underlying charge transport layer. Thermal annealing also affects the crystallinity, phase separation size, and the donor/acceptor interface, factors that all influence photovoltaic properties.
