Device Performance

NREL's device performance researchers perform current-voltage, quantum efficiency, and other measurements on a range of photovoltaic cell and module technologies—including commercial, developmental, and research samples—for scientists in the photovoltaic (PV) industry and at universities.

NREL is the United State's premier laboratory for testing the performance of PV cells and modules. We test devices of all types of PV technologies from around the world to ensure consistency and accuracy of PV performance measurements. Our equipment and techniques are unparalleled, and the expertise of our current staff covers more than 190 person-years.

Whether you are a PV manufacturer, certification lab, research organization, university, or national laboratory, we welcome the opportunity to test your cells and modules and provide certified data on spectral responsivity, power, efficiency, and other current versus voltage performance parameters. Our calibration services are available to customers from any country in the world. We now provide a full-service website where you can specify your desired PV device performance calibration services, provide sample information, print out required forms, and pay for measurements. This online measurement request process combined with our rapid turnaround time of six week or less means you can get needed calibration results faster.

For more extensive collaborative research projects, nonstandard testing, long-term testing, and testing a large numbers of samples there are several options for working with us.
