Improvement of accuracy and precision of spectral irradiance measurements in annual spectroradiometer intercomparison, 35th EUPVSEC, Sept 2018, Brussels, Belgium ...

Energy yield measurement and radiation yield determination in the field of photovoltaics (PV) are subject to fast development regarding estimation uncertainties and error in prediction [1]. Both are determined mainly by constraints given by equipment development, calibration schemes and operation routines. Further, an increasing range of PV technologies is available on the market showing rather different spectral responsivities. These require precise PV device calibrations, either outdoor or indoor, with accurate measurement of the light-source. Under these boundary conditions accurate spectra... Mehr ...
