A Claim for 100%+ Solar Cell Efficiency
December 22, 2011 | Leave a Comment
A research team at the National Renewable Energy Laboratory (NREL) report in Science the first photovoltaic solar cell that produces a photocurrent that has an external quantum efficiency greater than 100% when photoexcited with photons from the high energy region of the solar spectrum. For comparison external quantum efficiency for photocurrent is usually expressed as […]
