Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>A linear solution‐processable small molecule (BDT‐2DPP)</bold> based on 5‐alkylthiophene‐2‐yl‐substituted benzodithiophene and diketopyrrolopyrrole is designed and synthesized. BDT‐2DPP exhibits strong and broad absorption with low band gap, low lying energy levels matching with PC₆₁BM and high hole mobility. Solution‐processed organic solar cells based on BDT‐2DPP:PC₆₁BM blend showed power conversion efficiencies as high as 5.79%. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg36h2jjmb" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
