| Abstract: | JRC ESTI and PTB performed a comparison of spectral irradiance measurements on various light sources at the JRC premises. The measured sources included four standard lamps (two calibrated by PTB and two calibrated by NPL), global natural sunlight at clear sky conditions, a steady-state xenon-halogen solar simulator for solar cell calibration (Wacom) and a steady-state xenon large area solar simulator (Apollo). The PTB system is composed of three compact array spectroradiometers (CAS) equipped with Si, InGaAs, and extended range InGaAs detectors, respectively, in order to cover the wavelength range from 250 to 2150 nm. The JRC-ESTI rotating grating spectroradiometer is composed by a single stage monochromator and a Si-PbS sandwich detector in order to cover a wavelength range from 300 to 2500 nm. All instruments were calibrated in house by the respective owner institution using respective procedures and traceability chains. The measured spectra will be compared and deviations will be discussed with respect to the given uncertainties. Finally, exemplary spectral mismatch calculations will be shown in order to evaluate the impact of the deviations on PV device calibration. |
