The National Center for Photovoltaics (NCPV) at NREL has world-leading capabilities in characterizing photovoltaic (PV) materials and devices.

Device Performance

We have one of only two labs in the world to hold an ISO 17025 accreditation for primary reference cell and secondary module calibration, in addition to accreditation for secondary reference cell calibration under ASTM and IEC standards.

Electro-Optical Characterization

We apply a range of electro-optical characterization techniques to PV materials and devices with specialty in measuring minority-carrier lifetime.

Analytical Microscopy and Imaging Science

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.

Interfacial and Surface Science

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.
