Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201400647-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>The effectiveness of new a electron acceptor</bold> for organic solar cells is demonstrated. The acceptor is a homoleptic zinc(II) complex of 2, 6‐diphenylethynyl‐1, 3, 7, 9‐tetraphenylazadipyrromethene. The high power‐conversion efficiency obtained is attributed to the acceptor's 3D structure, which prevents crystallization and promotes a favourable nanoscale morphology, its high <italic>V</italic>_oc, and its ability to contribute to light harvesting at 600–800 nm. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh1f8bcz4c" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
