Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201303622-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>The addition of processing additives</bold> is a widely used approach to increase power conversion efficiencies for many organic solar cells. We present how additives change the polymer conformation in the casting solution leading to a more intermixed phase‐segregated network structure of the active layer which in turn results in a 5‐fold enhancement in efficiency. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg4053dh76" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
