Abstract

<abstract abstract-type="graphical" xml:lang="en" id="aenm201570078-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p>In article number 1500405, Todd Emrick, Thomas Russell, and co‐workers report the fabrication of inverted polymer solar cells with a maximum efficiency of 9.23% using a dual functional fullerene zwitterion as the cathode interlayer. C₆₀‐sulfobetaine acts as an electron acceptor and cathode modification layer. Exceptional insensitivity to interlayer thickness is found with efficiencies exceeding 8%. Slot‐die coated solar cells with an organic cathode interlayer have efficiencies of 7.38%. <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgj22v9b0p9" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </abstract>
