At ISE CalLab a spectral mismatch correction is applied to calibration of photovoltaic devices. Therefore, the knowledge of the relative spectral distribution of the solar simulator is mandatory. The spectral distribution of the solar simulator is as important as hard to control properly, especially for flash simulators often used for large modules and production lines. Knowing this spectral distribution allows to calculate the spectral mismatch. The spectral distribution of the solar simulator is the quantity least known in this procedure. For radiometric measurement a guideline exists [1], which excludes the special case of flash lamp measurements. For flash solar simulators it is more difficult to determine the spectral distribution. To measure the spectral distribution of such a flash pulse, single monochromator diode array spectroradiometers (SMDAS) are commonly used. The knowledge of the timing behaviour of SMDAS diode arrays and readout electronics is important for a spectroradiometric measurement of flash pulses. In this paper we discuss these properties in detail.
