Researchers at the University of Pittsburgh are working to improve the next generation of solar panels.

They’re using something called fused silica glass. Imagine tiny blades of grass, almost 1,000 times thinner than a human hair, tightly packed together.

That’s how the surface of fused silica glass will look under a microscope after Paul Leu, a professor of industrial engineering at the University of Pittsburgh, and Sajad Haghanifar, a Ph.D. student in Leu's lab, bombard the glass' surface with charged particles called ions.
