Moth eyes are incredibly efficient—reflecting almost no light, so they don’t draw attention from predators. Researchers from Switzerland are taking the absorption properties found in moth eyes and applying them to solar panel design. The new solar design covers the panels in a thin layer of tungsten oxide with iron oxide particles, mimicking the way moth eyes gather light. And while most solar panels convert light to energy, the new Swiss design uses the energy from the sun to split water molecules to make hydrogen fuel, which addresses the notorious problem of solar energy storage.
