Solar Energy Harvesting Using One Percent Of Current Materials

Abstract:
Imagine a world where sunlight can be captured to produce electricity anywhere, on any surface. The makers of thin-film flexible solar cells imagine that world too. But a big problem has been the amount of silicon needed to harvest a little sunshine.

Now, researchers [led by Harry A. Atwater] at CalTech say they've designed a device that gets comparable solar absorption while using just one percent of the silicon per unit area that current solar cells need.
