The complex eye of a moth may be the key to cheaper, more efficient solar panels
One of the problems plaguing solar cells is their inability to absorb all of the light they receive. Currently, the bluish anti-reflective coating you see on most cells is 60 or 65 percent efficient, meaning nearly a third of the light is bounced back into the sky. That's because the coating is only able to absorb a narrow range of wavelengths from the sun's rays. Now, however, researchers at the University of Florida and Portland State University think they may have found a better way and their inspiration comes from an unlikely source: moth eyes.
