The measurement facilities of the PV-calibration laboratory of the Fraunhofer-Institute for Solar Energy Systems (ISE) are presented. Calibration of PV devices of an area up to 10 x 10 qcm can be performed to an accuracy of 1,85%. Measurements include dark and light current-voltage characteristics, as well as the spectral response of solar cells. Both can be determined at arbitrary temperature and irradiation. Details on the measurement set-ups and modifications planned for multi-junction and concentrator solar cells will be described.
