Alta Devices has announced its latest world record for its gallium arsenide (GaAs) solar PV technology. The company has produced a 31.6% dual-junction cell at one sun, as verified by the U.S. Department of Energy's National Renewable Energy Laboratories (NREL). While higher efficiencies have been achieved with concentration, Alta had set a one-sun efficiency record for dual-junction PV at 30.8% in 2013. Shortly thereafter this record was bested by NREL, however now Alta has ...Den vollständigen Artikel lesen ...
