The folks at the National Renewable Energy Laboratory are applying a fabrication method for building highly efficient multi-junction solar cells to aid in the quest to increase LED efficiency for white light.

Green light: This gallium-indium phosphide LED was fabricated by researchers at the National Renewable Energy Laboratory.

Solar-cell manufacturing techniques could yield LEDs that require 20 percent less energy.

A new approach to fabricating light-emitting diodes (LEDs) could be used to increase their efficiency by 20 percent while yielding higher-quality light than conventional LEDs. Researchers at the National Renewable Energy Laboratory (NREL) in Golden, CO, have demonstrated the approach by making a yellow-green LED that could soon be combined with other colored LEDs to yield white light. The new LED could help replace current, inefficient methods of generating white light…
