Abstract

<abstract abstract-type="graphical" xml:lang="en" id="aenm201301771-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>A poly(thieno[3, 4‐b]‐thiophene/benzodi­thiophene) (PTB7)‐based polymer solar cell (PSC) with conventional structure</bold> can achieve a significant power conversion efficiency of 8.42%, which is realized by integrated optimization of both anode and cathode interlayers. The effects of a conjugated microporous polymer film as the anode interlayer are threefold: it enhances the contact with active layer, increases the work function and conductivity, and blocks electrons. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pghgxpb9k8" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
