Development of Au-Ag nanowire mesh fabrication by UV-induced approach

Abstract

In an attempt to overcome the limitations of the presently prevailing transparent conducting electrode (TCE) -indium tin oxide (ITO) -many materials have been considered for replacing ITO. Recently, a novel method has been reported for the synthesis of Au-Ag nanowire (NW) mesh, and tested successfully for organic-light-emitting-diodes (OLEDs). It employs UV-induced reduction of gold-and silver-precursors to form Au-Ag NW mesh. In this report, Au-Ag NW mesh thinfilms are synthesized on glass substrates with an objective for use as facing-electrode for Organic Photovoltaics. Various issues and factors affecting the fabrication-process have been improved, and are also discussed here. The electrode showed good transmitivity, of around 95% (excluding that of glass substrate). The advantage of the technique is its simple processing method and cost-effectiveness.
