Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201305160-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Transient photocurrent measurements</bold> are used to investigate the effects of processing additives on charge transport in small molecule bulk heterojunction solar cells. The additive decreased carrier recombination rates and improved carrier mobility, both of which are beneficial to carrier extraction. Geminate recombination of charge transfer excitons is ruled out by the data. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg5bxsxkrz" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
