The effects of solar simulator xenon flash lamp ageing and spectral output measurement uncertainty on the spectral mismatch are investigated. Measurements showed large unexpected variations due to measurement uncertainty in the spectral measurements themselves. A faulty temperature control is found to be the main source of uncertainty. It is shown that this alone can affect the mismatch calculation to a larger degree than the MMF would correct in itself.
