title: A-D-A-type S,N-heteropentacenes: next-generation molecular donor materials for efficient vacuum-processed organic solar cells.
abstract: 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 (JSC ) and fill factor (FF).
