Solar Junction, in partnership with NREL, has developed solar cells that reach a record-breaking 44 percent efficiency -- meaning that more than 40 percent of the sunlight the solar cells are exposed to is converted into electrical energy. In this photo, an operator inspects a photolithography tool used to manufacture these solar cells. | Photo by Daniel Derkacs/SolarJunction.

What do butterflies and solar cell research have in common? Both have been developing tiny crystals that selectively reflect colors. Over millions of years of evolution, butterfly wings have developed the tiny crystal nanostructures that give butterflies their vivid colors. At Argonne National Laboratory, scientists are working to manufacture these crystals, which could one day be used to create "greener" and more efficient paints, fiber optics and solar cells. In this photo, the iridescent scales of an emerald-patched Cattleheart butterfly are magnified 20 times to highlight the crystals that selectively reflect green colors. | Photo courtesy of Argonne National Laboratory.

The preamplifiers of the National Ignition Facility are the first step in increasing the energy of laser beams as they make their way toward the target chamber. NIF recently achieved a 500 terawatt shot - 1,000 times more power than the United States uses at any instant in time. | Photo by Damien Jemison/LLNL
