Bugs inspire better solar cell
Form microscopic pillars on a glass
surface and you have a solar cell top layer that cuts glare and keeps
The antireflective coatings are made by shaping a glass surface
with closely packed microscopic spheres. The resulting microscopic
pillar arrays mimic the antireflective surfaces of moth eyes and the
hydrophobic surfaces of cicada wings.
Cutting glare and dirt on solar cells increases the amount
of light they can convert to electricity.
