Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adom201300254-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Experimental demonstration of silicon inverse opal photonic crystals</bold> (PhCs) as a wave‐optics‐based back reflector for polycrystalline silicon solar cells is shown. Using a novel S⁵ process, crack‐free three dimensional PhCs are fabricated, which are free‐standing and have good optical properties. An efficiency enhancement of 10% is measured for 1.5 μm‐thick commercial silicon solar cells, matching reasonably well with simulations. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg3srrjv54" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
