NREL has world-leading capabilities in the characterization of photovoltaic (PV) materials and devices.
We provide certification, testing, and calibration services for the entire range of PV technologies—with measurement uncertainties among the best in the world—and help define global standards and best practices for PV calibration.
We apply a range of electro-optical characterization techniques to PV materials and devices with specialty in measuring minority-carrier lifetime.
We apply transmission/scanning electron and scanning probe techniques to measure the chemical, structural, morphological, electrical, interfacial, and luminescent properties on the nano to Angstrom scale.
We develop and apply a wide range of techniques to determine the chemical, elemental, and molecular composition, and the electronic structure of surfaces and critical interfaces.
