Space solar cell and panel manufacturer Spectrolab has broken its own solar cell efficiency world record. The Boeing subsidiary achieved an efficiency of 38.8 percent for a ground-based multi-junction solar cell without the use of concentrated sunlight, breaking their former record by one percent. The U.S. Department of Energy‘s National Renewable Energy Laboratory in Golden, Colorado independently verified the record.

The Sylmar, California-based company’s previous record of 37.8 percent was set in April. Analysts Lux Research predicts that by 2022 Spectrolab cells could reach 50 percent efficiency. And Boeing says the new semiconductor bonding technology could be used to power spacecraft and unmanned aerial vehicles.
“Improving solar cell manufacturing technology is at the core of what we do at Spectrolab,” said Spectrolab President Troy Dawson. “We will continue to innovate new ways to achieve even better results.”
