However, experimental results have fallen far short of the ultra-high efficiency (i.e. beyond Shockley-Queisser limit) predicted by theoretical simulations. This limits the commercial application of these materials. Here, a non-transparent organic solar cell with an array of Ag/ZnO nanowires has been experimentally fabricated to increase the internal quantum efficiency (IQE) by a factor of 2.5 compared to a planar counterpart. This result indicates a significant enhancement of charge collection efficiency due to the ultrafast Ag nanowire channels. This hybrid nanostructure can also serve as a perfect back reflector for semi-transparent solar cells, which can result in enhanced light absorption by a factor of 1.8 compared to the reference samples. The enhanced charge collection and light absorption can make these Ag/ZnO nanostructures available for the application of modern optoelectronic devices.</dcterms:abstract> <dc:creator>Schmidt-Mende, Lukas</dc:creator> <dc:contributor>Park, Yoonseok</dc:contributor> <dc:creator>Leo, Karl</dc:creator> <dc:contributor>Schmidt-Mende, Lukas</dc:contributor> <dcterms:hasPart rdf:resource="https://kops.uni-konstanz.de/bitstream/123456789/46299/3/Feng_2-5h3h4bll0gd2.pdf"/> <dc:rights>terms-of-use</dc:rights> <dc:language>eng</dc:language> <dc:creator>Dorman, James</dc:creator> <dc:creator>Wang, Yongtian</dc:creator> <dc:contributor>Kim, Kwang-Dae</dc:contributor> <dc:creator>Nemitz, Clayton A.</dc:creator> <dc:creator>Weickert, Jonas</dc:creator> <dc:creator>Park, Yoonseok</dc:creator> <dc:contributor>Leo, Karl</dc:contributor> <dc:creator>Kim, Paul</dc:creator> <dc:creator>Kim, Kwang-Dae</dc:creator> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2019-07-10T11:27:31Z</dcterms:available> <dspace:hasBitstream rdf:resource="https://kops.uni-konstanz.de/bitstream/123456789/46299/3/Feng_2-5h3h4bll0gd2.pdf"/> <dc:contributor>Nemitz, Clayton A.</dc:contributor> <dcterms:isPartOf rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/41"/> <dcterms:rights rdf:resource="https://kops.uni-konstanz.de/page/termsofuse"/> <dc:contributor>Feng, Yuyi</dc:contributor> <dc:creator>Feng, Yuyi</dc:creator> <dcterms:issued>2019-04</dcterms:issued> <dc:contributor>Wang, Yongtian</dc:contributor> <dcterms:title>Boosting charge collection efficiency via large-area free-standing Ag/ZnO core-shell nanowire array electrodes</dcterms:title> <dc:contributor>Dorman, James</dc:contributor> <dspace:isPartOfCollection rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/41"/> <bibo:uri rdf:resource="https://kops.uni-konstanz.de/handle/123456789/46299"/> <dc:contributor>Kim, Paul</dc:contributor> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2019-07-10T11:27:31Z</dc:date> <dc:contributor>Weickert, Jonas</dc:contributor> <foaf:homepage rdf:resource="http://localhost:8080/jspui"/> </rdf:Description> </rdf:RDF>
