DOE/National Renewable Energy Laboratory (NREL) scientists have fabricated a solar cell with an efficiency of nearly 50%. The six-junction solar cell now holds the world record for the highest solar conversion efficiency at 47.1%, which was measured under concentrated illumination. A variation of the same cell also set the efficiency record under one-sun illumination at […]

The Fraunhofer Institute for Solar Energy Systems ISE, Soitec, CEA-Leti and the Helmholtz Center Berlin jointly announced achieving a new world record for solar cell efficiency.  Using a new solar cell structure with four solar subcells the team surpassed all the competition after only over three years of research.  The new record efficiency of 44.7% […]
