Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201402448-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>A new class</bold> of acceptor‐substituted <italic>S, N</italic>‐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 (<italic>J</italic>_SC) and fill factor (FF). <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh2cn0xf1b" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
