of solar simulator xenon flash lamps and spectral
output measurement uncertainty on the
spectral mismatch are investigated. It is
demonstrated that the spectrum of an older
lamp set has a relatively lower blue and larger
red content compared to a new set of bulbs.
Measurements over the life-time of several sets
of bulbs showed large unexpected variations
due measurement uncertainty in spectral
measurements themselves. The main influencing
factors are investigated and 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.
