The NREL Photovoltaic (PV) Device Performance group provides certification, testing, and calibration services that help set global standards while defining industry best practices. We help PV researchers, manufacturers, and labs assess the performance of their products.
We’re the only U.S. laboratory certified to calibrate primary reference cells, secondary reference cells, secondary reference modules, cells, and modules. We perform calibrations and measure performance parameters—such as efficiency—on the entire range of PV technologies, achieving measurement uncertainties equal to or lower than any other lab in the world. We test hundreds of cells and modules every month and consult with hundreds of entities on PV measurements and solar simulation each year.
