Instituto de Energía Solar at the Universidad Politécnica de Madrid has certified that Semprius’ HCPV modules have set a new world record with an efficiency level of 33.9%. The module was tested indoors at Standard Test Conditions (850 W/m2, 25°C cell temperature, and a spectrum matched to AM1.5D) and corroborated by outdoor measurements made at the Institute of Concentration Photovoltaic Systems (ISFOC) in Puertollano, Spain. The HCPV modules significantly exceed the previous claim of 32.0%.
“This is a significant milestone for Semprius and the entire PV industry,” said Scott Burroughs, vice president of technology at Semprius. “For the first time, we have been able to convert more than one-third of the sun’s energy into usable electricity. This demonstrates how concentrated PV can leverage rapidly increasing efficiencies to continue driving down the cost of solar generated electricity.”
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.
Following Siemens' acquisition of a 16% minority stake last summer and with the support of the US 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.
“Semprius as a leader in HCPV modules shows us that we have bet on the right technology,” said Martin Pfund, CEO of the Siemens Energy Photovoltaic Business Unit. “The world record is a breakthrough in module efficiency. Combined with our expertise in turnkey solutions business, it has the potential to become a game changer for the solar markets in regions with high irradiation. With Semprius as a partner, we will further broaden our portfolio in the photovoltaics market. We’re very pleased to be working together with Semprius to commercialize this technology globally.”
