Semprius Achieves 35.5 Percent Efficiency with CPV Solar Module

Semprius, Inc. of Durham, North Carolina USA, a maker of high concentration
photovoltaic (HCPV) solar modules, has reached 35.5 percent efficiency at
Concentrator Standard Test Conditions (CSTC). The result, which was confirmed
by the Fraunhofer Institute for Solar Energy Systems ISE in Germany,
significantly exceeds Semprius’ previous record of 33.9 percent,
announced in January 2012. The record module was produced on the production
line at Semprius’ new manufacturing facility in Henderson, N.C. The
module incorporates standard production techniques and materials, including
epitaxial wafers from Solar Junction. At over 35 percent, Semprius says its
modules are two to three times more efficient than conventional photovoltaic
modules and significantly higher than other commercially available HCPV
modules. Semprius also recently built an R&D demonstration module that
achieved an efficiency of 37.1 percent at CSTC.

“We are particularly pleased that we were able to produce this new
record on our pilot production line just months after opening the
said Joe Carr, CEO at Semprius. “This is a
testament not only to our R&D and manufacturing teams, but also to our
production process which is robust and scalable. We are now focused on
continuing to ramp up production capacities to deliver increasing volumes of
these high-performance, high-efficiency modules globally.”

Scott Burroughs, vice president of technology at Semprius said,
“Our R&D team continues to raise the bar for solar module efficiency
as it executes against our product roadmap.”
