Abstract

<abstract abstract-type="graphical" xml:lang="en" id="aenm201400568-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>High‐efficiency, vacuum‐deposited small‐molecule organic tandem and triple‐junction photovoltaic cells</bold> are demonstrated. The devices are composed of two sub‐cells with minimal absorption spectral overlap. A nearly transparent fullerene/wide‐energy gap organic mixture is introduced as the interconnecting blocking layer to further reduce cell losses. A power conversion efficiency of 10.0% is achieved for the tandem cell and 11.1% is achieved for a triple‐junction cell. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh2zjs1kn9" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
