The US Department of Energy’s National Renewable Energy Laboratory (NREL) has confirmed 13.2 per cent aperture area efficiency for a module made by global thin-film solar cell manufacturer Global Solar Energy using its production-line thin film solar material.
‘Global Solar Energy is the first company to exceed the 13 per cent efficiency target using thin films on a flexible stainless steel substrate, and joins a small number of PV companies who have met this high efficiency milestone for large thin film power modules,’ said Dr Ryne Raffaelle, director of NREL’s National Center for Photovoltaics. ‘This result is remarkable, given that the module was made using standard production equipment and manufacturing processes at Global Solar Energy.’
CIGS solar product manufacturer Global Solar Energy said it has been selling CIGS thin-film products on a flexible substrate for over six years.
Dr Jeff Britt, CEO, Global Solar Energy, said, ‘This achievement elevates us into the ranks of the few thin film companies to surpass this efficiency and is the culmination of a year of steady and rapid improvement in efficiency and yield at our production plants in both Arizona and Germany.’
Operated for the US Department of Energy by The Alliance for Sustainable Energy, the National Renewable Energy Laboratory (NREL) is the primary laboratory in the US for renewable energy and energy efficiency research and development (R&D).
