Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201401987-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>The <italic>V</italic>_OC loss in several polymer–fullerene solar cells</bold> is determined. Based on these data, a major source of photovoltage loss is attributed to the low dielectric constants of the polymers. Such loss is close to zero if the dielectric constant of the polymer–fullerene blend is close to 5. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh1c43c7xn" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
