Image title | August 24, 2010-NREL Research scientist Hao-Chih Yuan is reflected in a highly reflective untreated silicone wafer (left) compared to a silicone wafer that has been etched (right) . The simple etching process creates a nano porous silicon surface creating 10 nano- meter diameter holes in the surface. He is woking in a lab at the SURF building at NREL in Golden, CO.

Headline | A silver wafer reflects the face of NREL research scientist Hao-Chih Yuan, before the wafer is washed with a mix of acids. The acids etch holes, absorbing light and turning the wafer black. |
