Terrestrial Triple-Junction Array Generates Kilowatt Solar Power

SolarA kilowatt-scale terrestrial solar-cell array that employs III-V-based triple-junction technology could spur the improvement of both space-based and terrestrial solar-energy systems.At the summit of Mount Haleakala, on the island of Maui in Hawaii, engineers have deployed and tested what is believed to be the first ever 1 kW terrestrial triple-junction solar array. Developed by a team comprising the NASA Glenn Research Center, Boeing and Texas-based Entech, the concentrator array outputs more than 200 Wm-2 at 600 V. This achievement promises to improve solar-power generation using high-voltage arrays in terrestrial and space applications.
