Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201500465-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Highly efficient planar perovskite optoelectronic devices</bold> are realized by amine‐based solvent treatment on compact TiO₂ and by optimizing the morphology of the perovskite layers. Amine‐based solvent treatment between the TiO₂ and the perovskite layers enhances electron injection and extraction and reduces the recombination of photogenerated charges at the interface. <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgjwxbpzq9" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </abstract>
