Thus, calibration services are available for nearly all kinds of PV-devices; including wafer-based standard silicon solar cells in lab and industrial formats, as well as thin-film devices from various materials.
CalLab PV Cells continues to develop additional calibration experience, allowing for measurements which do not (yet) fall under the accreditation. These calibrations and measurements are performed with the same equipment and reference standards as accredited calibrations.
The determination of the spectral response of a device is always necessary if a device is to be calibrated. First, we must always determine the linearity of the short circuit current of the device with irradiation using the White-Light-Response (WLR) technique (see ).
The SR(λ)-measurement is then done in respect to a primary calibrated reference cell. For the IV-curve measurement, a simulator with constant irradiation is used. The irradiation spectrum (Class A) is measured on a regular basis with a spectroradiometer, which is calibrated in house against a PTB-calibrated standard lamp.
The calibrated measurements of the IV-curve parameters and the spectral response curves of solar cells constitute our standard services as an ISO 17025 accredited lab. Calibrations are performed under standard testing conditions (STC), as defined in the IEC 60904 series of standards.
Fraunhofer ISE CalLab PV Cells has been accredited as a calibration lab with the “Deutsche Akkreditierungsstelle GmbH” DAkkS (Registration number: D-K-11140-01-00), according to ISO 17025 since 2008 (former DKD).
