Abstract

<abstract abstract-type="graphical" xml:lang="en" id="smll201402905-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>The nonexcitonic character for organometal trihalide perovskites</bold> is demonstrated by examining the field‐dependent exciton dissociation behavior. It is found that photogenerated excitons can be effectively dissociated into free charges inside perovskite without the assistance of charge extraction layer or external field, which is a stark contrast to the charge‐separation behavior in excitonic materials in the same photovoltaic operation system. <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgjkz8vhg3" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </abstract>
