Semprius Inc has reached an efficiency of 33.9% with one of its concentrating photovoltaic (CPV) solar modules.
The solar CPV 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 is a significant milestone for Semprius and the entire PV industry," says 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 uses a micro-transfer printing process to produce the solar CPV modules, which is the size of a pencil point.
