Solar cells don't at first glance have any relation to a tiny structure in the eye that makes our central vision sharp, but that tiny structure – called the fovea centralis – may be the key to a huge boost in solar cell efficiency. A team of scientists at Helmholtz-Zentrum Berlin and the Max Planck Institute for the Science of Light took the underlying mechanisms that guide the fovea and adapted them to silicon as a surface for collecting light in solar cells.
