Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201302159-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Addition of low concentrations</bold> (&lt;1:100, dopant:donor) of a fluorinated p‐type dopant, F4‐TCNQ leads to a considerable enhancement of the photocurrent in PCDTBT:PC₇₀BM bulk heterojunction solar cells. As a result, the power conversion efficiency increases from 6.41% to 7.94 %. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg3zsqf2r1" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
