Abstract

<abstract abstract-type="graphical" xml:lang="en" id="admi201570065-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p>Silver is a low‐cost electrode material for perovskite solar cells. However, silver electrodes turn yellow after device fabrication, which is accompanied by a decrease in power conversion efficiency. These changes are caused by the formation of silver iodide from the reaction between silver and iodine‐containing compounds from the perovskite layer, as demonstrated by Y. B. Qi and co‐workers in article 1500195. The presence of pinholes in spiro‐MeOTAD hole‐transport layer facilitates silver iodide formation. <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgj2n0r1m71" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </abstract>
