NREL has developed "dark solar" which will reduce the refelectivity of solar panels and boost their energy output.

GOLDEN, CO - MAY 20: Researchers at the National Renewable Energy Lab, NREL, has developed a process called "dark solar" that will cut the reflectivity of solar panels which will boost their energy output. The reflection of one researcher on the project, Hao-Chih Yuan, can be seen on a sample of the dark silicon before it goes through the chemical process, right. The sample on the left is after the process and it appears nearly black. (Photo By Kathryn Scott Osler/The Denver Post via Getty Images)
