Abstract

<abstract abstract-type="graphical" xml:lang="en" id="aenm201501282-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>A novel D‐A₁‐D‐A₂‐type polymer that exhibits a small bandgap of 1.43 eV</bold> yet still yields polymer solar cells with a high open‐circuit voltage (<italic>V</italic>_OC) of 0.81 V and power conversion efficiencies of up to 8.63% is reported. Comparable efficiencies can be achieved even when the active layer is processed in air or after it is thermally annealed at 150 °C. <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgkss19t6q" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </abstract>
