Abstract

<abstract abstract-type="graphical" xml:lang="en" id="aenm201400166-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Organic dyes for solid‐state sensitized solar cells</bold> are commonly prepared by combining an electron‐withdrawing group (acceptor, A) on one side of a conjugated π‐spacer and one or more electron‐donating groups (donor, D) on the other side. It is shown that without an electron donor group a significantly higher open‐circuit voltage is achieved, while maintaining the short‐circuit current. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh1c9n69hw" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
