DANSK DS/EN 60904-8 PDF

This part of IEC 60904 gives guidance for the measurement of the spectral response of both linear and non-linear photovoltaic devices. It is only applicable to single-junction devices. The spectral response of a photovoltaic device is used for the correction of the spectral mismatch if a solar cell is calibrated in a spectrum that differs from the reference spectrum and against a reference device with a different spectral response. This procedure is given in IEC 60904-7. Also, the spectral response of a photovoltaic device is used in cell development and cell analysis, as it provides a measure of recombination and other processes occurring inside the semiconductor or cell material system.
