Ultrafine gold nanowire networks as plasmonic antennae in organic photovoltaics

Solution-processed ultrafine gold nanowires (Au-NWs) have been exploited as plasmonic antennae in organic P3HT:PCBM photovoltaic cells. The careful reduction of the spacer layer thickness which allows the evanescent field to be extended into the photoactive layer and the geometry of the Au-NWs bands...
