• 33.9% active area efficiency confirmed by the Instituto de Energía Solar of the Universidad Politécnica de Madrid

The module was tested indoors at Standard Test Conditions (850 W/m2, 25°C cell temperature, and a spectrum matched to AM1.5D) by the Instituto de Energía Solar at the Universidad Politécnica de Madrid (IES-UPM). This efficiency result, certified by the IES-UPM and corroborated by outdoor measurements made at the Institute of Concentration Photovoltaic Systems (ISFOC) in Puertollano, Spain, significantly exceeds the previous claim of 32.0 percent.

Semprius delivers a unique HCPV module design that begins with its proprietary micro-transfer printing process. This process enables the company to fabricate the world’s smallest solar cell – approximately the size of a pencil point – to create solar modules with unmatched efficiency and performance.

After developing its module with the support of the U.S. Department of Energy’s National Renewable Energy Laboratory, Semprius is now ramping up global deployment of demonstration systems while completing construction of a pilot plant in Henderson, North Carolina. Commercial production at the plant will begin during the second half of 2012.
