Device Harvests Untapped Solar Power
Researchers in Abu Dhabi have created a low-cost device that can make solar cells panels more efficient by splitting sunlight into its constituent colors.
The plastic device both concentrates and separates sunlight into its key spectral components: all the visible colors of the rainbow and invisible infrared. This allows for the layering of solar cells so each colored ray is directed onto a solar panel designed to convert this colour at maximum efficiency, the researchers say.
