Solar 1

Caption: Rice University scientists have reduced to one step the process to turn silicon wafers into the black silicon used in solar cells. The advance could cut costs associated with the production of solar cells. Here, a cross section shows inverted pyramids etched into silicon by a chemical mixture over eight hours.
