The director of America’s National Renewable Energy Laboratory (NREL), Dan Arvizu, gave a keynote speech during the 2013 International Renewable Energy Conference (part of Abu Dhabi Sustainability Week), part of which focused on the current state of efficiencies in solar modules and cells. According to CleanTechnica‘s Zachary Shahan, who attended the conference and interviewed Arvizu on the conference sidelines, the NREL director’s points on the subject – which are embodied in the graph below – were that the current efficiencies of all types of solar modules and solar cells are nowhere near their theoretical efficiency limits; and that thin-film solar is especially ripe for efficiency improvements, as are concentrated photovoltaics.
