The finding could lead to solar panels that are glare-resistant.

IRVINE, CA - "We found that a very simple process and a tiny bit of gold can turn a transparent film black," UC Irvine chemistry professor Robert Corn, said in a news release.

The study started when the researchers noticed what they thought was soot on a flexible film they were working on. Instead of looking at this as a bad thing the researchers saw it as an opportunity to create a surface that is resistant against glare. The material could also keep grime and liquid from sticking to the screen or damaging it.

The team etched a pattern of the cones on moth eyeballs on Teflon. The team then applied a thin layer of gold over this nanoscale etching.

The team found that they shine from any light shining in the surface was eliminated and the material was also hydrophobic, meaning it repelled water…
