Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201404152-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>A tetraphenylethylene core‐based small molecular acceptor</bold> with a unique 3D molecular structure is developed. Bulk‐heterojunction blend films with a small feature size (≈20 nm) are obtained, which lead to non‐fullerene organic solar cells (OSCs) with 5.5% power conversion efficiency. The work provides a new molecular design approach to efficient non‐fullerene OSCs based on 3D‐structured small‐molecule acceptors. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh3s8pzp5z" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
