Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Thin‐film, microscale GaAs solar cells transfer printed into luminescent concentrating waveguides</bold> show significantly enhanced power output compared to cells evaluated in isolation. Experimental and numerical simulation results demonstrate that optimized configurations involve a free‐standing waveguide and a diffuse backside reflector, as a way to maximize capture of both waveguided and scattered photons. Such unusual options in engineering design suggest promising additional avenues for the use of luminescent concentration in advanced photovoltaics. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg36h3q99m" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
