"The eyes of nocturnal moths contain a series compound lenses: micro lenses called ommatidia which are themselves patterned with a nanoscale dome-shaped bumps. These structures naturally help reduce reflection of light at a wide range of wavelengths, enabling better night vision to help moths navigate in the dark. [...] The ability to capture light and not let go is appealing in the world of solar cells because it can increase efficiency. So the team from Singapore has taken inspiration from the complex lens structure to create a process that stamps patterns over the surface of a material, replicating the antireflective effects of the moths' eyes.
