Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201570007-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p>On page 41, J. H. Cho and co‐workers demonstrate a high performance novel photodetector consisting of graphene and a CH₃NH₃PbI₃ perovskite layer, which exhibit a dramatic enhancement of photoresponsivity and effective quantum efficiency with a broad spectral bandwidth. The ultrahigh performance of the perovskite–graphene hybrid photodetector arises from the enhanced photon absorption of the hybrid film and the effective gain effect induced by trapped photoexcited electrons in the perovskite layer. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh30v92j3m" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
