Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201402782-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>A high‐performance parallel tandem solar cell</bold> employing ultra‐thin Ag as the intermediate anode is demonstrated, which comprises a semitransparent front sub‐cell and a microcavity assisted back sub‐cell. In addition to the extended optical field as a result of the tandem architecture, the prominent microcavity resonance formed in the back sub‐cell enables such a parallel tandem configuration to possess high light utilization efficiency (the peak EQE value is over 80%) and a high photovoltaic performance of 9.2%. This study establishes an effective architecture that can be generally applicable to all organic materials for improving their performance. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh2cgh0640" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
