Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201405226-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>The effectiveness of side‐chain engineering</bold> is demonstrated to produce highly efficient all‐polymer solar cells (efficiency of 5.96%) using a series of naphthalene diimide‐based polymer acceptors with controlled side chains. The dramatic changes in the polymer packing, blend morphology, and electron mobility of all‐polymer solar cells elucidate clear trends in the photovoltaic performances. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgjhx62r64" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
