Abstract

<abstract abstract-type="graphical" xml:lang="en" id="aenm201570080-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p>A strategic approach for designing a novel hole‐transporting material in perovskite hybrid solar cells and synthesizing a donor‐p‐acceptor polymeric hole conductor (TTB‐TTQ) is reported by Taiho Park and co‐workers in article number 1500471. A rough film surface with a fibril structure induced by (lithium bis(trifluoromethanesulfonyl) imide (LiTFSI) salt and tert‐butylpyridine (tBP) enhances the scattering effect and improves charge transport, resulting in a high efficiency (14.1%) with a high short‐circuit current density (<italic>J</italic>_SC = 23.9 mA cm⁻²). <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgj22v9b3z8" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </abstract>
