Sefar

Sefar AG (Switzerland) produces highly conductive, transparent and robust electrode materials for large area optoelectronics. These electrodes, containing fine metallic wires are suitable for printed and evaporated devices such as flexible OLEDs and various types of solar cells, including perovskite-based ones.

The Sefar electrodes can either be used as a substrate (to coat on it), as a grid-fabric (to laminate on top of a device), or even as a tandem-substrate (conductive on both sides).
