A group of researchers at Helmholtz-Zentrum in Berlin have developed a new structure to improve the efficiency of solar cells. It is based on the structure of human eyes. More exactly in a region called fovea centralis.
This structure is made of inverted cones that connect directly to nerves. The cones are very thightly placed making the system to work better. They are easily manufactured and don’t need complex procedures.
The research team found that the efficiency of this new fovea based structure was up to 65% better than a conventional silicon film.
