Abstract

<abstract abstract-type="graphical" xml:lang="en" id="aenm201470094-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p>High‐efficiency solution‐processed organic solar cells based on narrow‐bandgap π‐conjugated oligomers are demonstrated by Takuma Yasuda, Chihaya Adachi, and co‐workers in article number 1400879. Well‐organized donor/acceptor bulk‐heterojunction domains with pronounced mesoscopic phase segregation are spontaneously formed in a photoactive binary blend layer. A high power conversion efficiency of 5.9% is achieved for small‐molecule organic solar cells. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh2qxd5fw0" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
