New Record for HCPV Solar Modules


Semprius sets new record for commercially available solar modules, reaching a 35.5% efficiency rate at Concentrator Standard Test Conditions.

 Semprius, an innovator in high concentration photovoltaic (HCPV) solar modules, has reached a 35.5% efficiency rate at Concentrator Standard Test Conditions (CSTC), as confirmed by the Fraunhofer Institute for Solar Energy Systems ISE in Germany. The improved efficiency rate sets a new record for mass-produced PV module efficiency. Semprius’ previous record was 33.9%, which was announced in January 2012.

At over 35%, Semprius modules are the highest efficiency of any commercially available product in the PV industry – two to three times more efficient than conventional photovoltaic modules and significantly higher than other commercially available HCPV modules.

The record module was produced on the production line at the company’s new manufacturing facility in Henderson, N.C. The module incorporates standard production techniques and materials, including epitaxial wafers provided by Solar Junction, an important partner of Semprius.

The firm’s technology is ideally suited for the world’s sunniest regions, where its high-temperature performance and dual axis tracking enable high energy production yields throughout the day. In sunny locations like the US Southwest, Saudi Arabia, Mexico, and Chile, its systems can deliver up to 30 percent more energy than equivalent, conventional fixed-tilt photovoltaic systems.

“We are particularly pleased that we were able to produce this new record on our pilot production line just months after opening the facility,” said Joe Carr, Chief Executive Officer 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.”

In addition to producing a 35.5% commercial module, Semprius also recently built an R&D demonstration module that achieved an efficiency of 37.1% at CSTC.

“Our R&D team continues to raise the bar for solar module efficiency as it executes against our product roadmap,” said Scott Burroughs, vice president of Technology at Semprius. “We have an extensive program of efficiency improvements and cost reductions over the next several years that will allow us to continue to improve performance and drive down the cost of solar energy.”
