Results of the IX International Spectroradiometer Intercomparison and impact on precise measurements of new photovoltaic technologies

AbstractToday's variety of photovoltaic (PV) technologies imposes new challenges to laboratories and industries to precisely measure the performance of devices and, consequently, to accurately estimate the energy yield once installed in a specific location. Spectroradiometry has become a key discipline for metrology applied to PV: Spectral irradiance is one of the three parameters according to which solar simulators are classified according to IEC 60904‐9; precise spectrum measurements are a key factor in the spectral mismatch calculation. Finally, energy rating calculations according to IEC 6... Mehr ...
