Semprius Inc., a developer of high-concentration photovoltaic (HCPV) solar modules, says it has set a new record for photovoltaic module efficiency, at 33.9% (active area).
The module was tested indoors at standard test conditions (850 W/m2, 25 degrees C cell temperature and a spectrum matched to AM1.5D) by the Instituto de Energia Solar at the Universidad Politecnica 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 in Puertollano, Spain, significantly exceeds the previous claim of 32%, according to Semprius.
