Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201501626-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Novel wide‐bandgap semiconducting polymers</bold> are designed and synthesized for multijunction polymer solar cell (PSC) applications. In single‐junction PSCs, BDT‐FBT‐2T exhibits efficiencies exceeding 6.5% for active layer thicknesses between 90 and 250 nm, with the highest efficiency of 7.7% at 100 and 250 nm. This enables tandem PSCs to be created with an efficiency of 8.9%. <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgj2cr1z7zm" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </abstract>
