Silver nanowire networks for ITO replacement — •Julian Reindl and Lukas Schmidt-Mende — Department of Physics, University of Konstanz, Germany

Indium-tin oxide (ITO) is the state-of-the-art material for transparent electrodes in optoelectronic devices such as solar cells. However, Indium is a very scarce material and the increasing demand for transparent conductors drives the need for alternative materials.

Here we present networks of silver nanowires which are embedded in a matrix of the doped polymer PEDOT:PSS. This system enables a good conductivity through the metallic pathways, supported by the polymer. The latter also provides a good light transmission in the visible range.
