Spectrolab III-V solar cell beats own record with 38.8% efficiency

The firm uses Boeing's semiconductor bonding technology which could be be used to power high-power spacecraft and unmanned aerial vehicles
Boeing subsidiary Spectrolab has set a new world record by producing a solar cell that converted 38.8 percent of solar energy into electricity, more than any other ground-based solar cell not using concentrated sunlight.

The U.S. Department of Energy's National Renewable Energy Laboratory in Golden, Colorado, verified the new record, which beats Spectrolab’s own previous world record by 1 percent.

"Improving solar cell manufacturing technology is at the core of what we do at Spectrolab,” says Spectrolab President Troy Dawson. “We will continue to innovate new ways to achieve even better results.”

Spectrolab manufactured the high-efficiency multi-junction solar cell, which was developed from new Boeing semiconductor bonding technology. This solar cell technology could be used to power high-power spacecraft and unmanned aerial vehicles.

Spectrolab, part of Boeing Defence, Space & Security, is a merchant supplier of high-efficiency multi-junction solar cells and panels for concentrated photovoltaic and spacecraft power systems, in addition to being the a provider of airborne searchlights.



Connecting the Compound Semiconductor Industry

The 13th CS International conference builds on the strengths of its predecessors, with around 40 leaders from industry and academia delivering presentations that fall within five key themes: Ultrafast Communication; Making Headway with the MicroLED; Taking the Power from Silicon, New Vectors for the VCSEL, and Ultra-wide Bandgap Devices.

Delegates attending these sessions will gain insight into device technology, find out about the current status and the roadmap for the compound semiconductor industry, and discover the latest advances in tools and processes that will drive up fab yields and throughputs.
