A new class of acceptor‐substituted S,N ‐heteropentacenes is developed for vacuum‐processed organic solar cells, providing encouraging power conversion efficiencies of up to 6.5%. Atomic force microscopy (AFM) investigations give a direct correlation between the blend film morphology and the photovoltaic parameters, such as short‐circuit current density ( J SC ) and fill factor (FF).
