Until now, four-junction III–V concentrator solar cells have demonstrated the highest solar conversion efficiencies. Here, we demonstrate 47.1% solar conversion efficiency using a monolithic, series-connected, six-junction inverted metamorphic structure operated under the direct spectrum at 143 Suns concentration. Furthermore, when tuned to the global spectrum, a variation of this structure achieves a 1-Sun global efficiency of 39.2%. Nearly optimal bandgaps for six junctions were fabricated using alloys of III–V semiconductors. To develop these junctions, it was necessary to minimize threading dislocations in lattice-mismatched III–V alloys, prevent phase segregation in metastable quaternary III–V alloys and understand dopant diffusion in complex structures. Further reduction of the series resistance within this structure could realistically enable efficiencies over 50%. </p> </div></div> </section> <div id="biblio-nav" class="row mb-2 d-md-block position-sticky d-print-none"> <div class="container"> <div class="row small align-flex-end" id="navbar-top"> <div class="col-xs-12 col-lg-6" style="padding:0;padding-top:0.5rem;"> <div style="display:inline-block;"> <a style="margin:0.5em;" class="pure-button button-success fulltext-link" data-ostiid="1659948" data-product-type="Journal Article" data-product-subtype="AM" href="/servlets/purl/1659948" target="_blank" rel="noopener"><span class="fa fa-download" style="margin-right:0.25em;"></span> View Accepted Manuscript (DOE)</a></div> </div> <div class="col-xs-12 col-lg-6 text-right" style="padding:0;padding-top:0.5rem;"> <div class="text-left d-inline-block p-relative"> <a href="#" data-jq-dropdown="#biblio-cite-options" style="padding:1em; white-space:nowrap;" data-vertical-offset="15">Cite <span class="fa fa-angle-down" style="color:#aaa;" aria-hidden="true"></span></a> <div id="biblio-cite-options" class="jq-dropdown jq-dropdown-tip jq-dropdown-relative" style="display: none; left: 0px; top: 16px;"> <div class="jq-dropdown-menu xs-shift-left-9" style="padding:1em;min-width:400px;"> <div class="biblio-cite" style="padding: 1rem;"> <h2 class="title-citeformat mt-0 mb-0-5">Citation Formats</h2> <div class="row mb-2"><div class="col-12"> <ul class="nav nav-tabs nav-tabs-cite small clearfix"> <li class="active"><a href="#biblio-cite-mla" class="tab-nav tab-nav-cite" data-tab="cite">MLA</a></li> <li><a href="#biblio-cite-apa" class="tab-nav tab-nav-cite" data-tab="cite">APA</a></li> <li><a href="#biblio-cite-chi" class="tab-nav tab-nav-cite" data-tab="cite">Chicago</a></li> <li><a href="#biblio-cite-bib" class="tab-nav tab-nav-cite" data-tab="cite">BibTeX</a></li> </ul> </div></div> <div class="row"><div class="col-12"> <section id="biblio-cite-mla" class="tab-content tab-content-cite active" data-tab="cite"> <div class="small"> <code id="biblio-cite-mla-code" style="display:block; max-height:150px; overflow:scroll; overflow-x:hidden;"> Geisz, John F., France, Ryan M., Schulte, Kevin L., Steiner, Myles A., Norman, Andrew G., Guthrey, Harvey L., Young, Matthew R., Song, Tao, and Moriarty, Thomas. <i>Six-junction III–V solar cells with 47.1% conversion efficiency under 143 Suns concentration</i>.
