Spire Corporation announced its wholly owned subsidiary, Spire Semiconductor, LLC, has matched the current efficiency record for a concentrator solar cell.
The record efficiency is available on a production ready cell with a photo area of 1.0 cm². The U.S. Department of Energy's National Renewable Energy Laboratory (NREL) measured the efficiency of 41.0% at 500x suns concentrated sunlight.
Spire is working with NREL to boost efficiency to 42.5%.
