Nano World: Black silicon for solar power

The novel treatment developed by researchers at the Technical University of Munich can cut the surface reflection silicon experiences by 95 percent to 98 percent across the wavelengths of light solar power cells use, making them black.

“The results are really good when it comes to preventing reflection. It is still speculative as to how much this can boost the efficiency of solar cells. I am optimistic that for traditional designs of solar cells, it could give a 15 to 20 percent improvement with respect to their present efficiency.
