Researchers from UCLA developed a new transparent electrode based on silver nanowires (AgNW) that is a replacement for ITO. The new electrode is made from low-cost and non-toxic materials and is easy to fabricate. It also offers high transparency, low sheet resistance and low surface roughness.
The new electrode is produced on a cross-linked, transparent polyacylate substrate, which is cheaper than glass and can be stiff and rigid or flexible and stretchable. The researchers say that the new electrode could be used to create a shape-memory polymer substrate that can be deformed to various stable shapes - and the deformation is reversible, causes minimal damage to the devices so it can be repeated many times.
