Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201401991-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Lead free perovskite solar cells</bold> based on a CsSnI₃ light absorber with a spectral response from 950 nm is demonstrated. The high photocurrents noted in the system are a consequence of SnF₂ addition which reduces defect concentrations and hence the background charge carrier density. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh2ch3c0zg" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
