NREL scientist Keith Emery examines a Semprius solar module at the laboratory's Outdoor Test Facility. NREL helped Semprius characterize and test its tiny solar cells, which are the diameter of a dot made by a ballpoint pen.
NREL's state-of-the-art testing and characterization instruments scrutinize the quality and efficiency of solar cells, such as on this module made by Semprius.
This solar cell module made by Semprius is being tested at NREL's Outdoor Test Facility.
