performance measurements for energy rating and energy
yield calculation derived indoors with an LED-based solar
simulator prototype under varying irradiance (G),
temperature (T) and spectrum (E), opening the possibility
for much faster and more accurate energy yield prediction
than previously possible from measurements acquired
either indoors or outdoors, with the additional inclusion of
spectral influences.
The main aspects of the LED-based solar simulator used
are described briefly and the measurement method with its
requirements is explained in detail. Also presented are the
first performance measurements made with an amorphous
silicon solar cell; measuring the spectral effects reported in
outdoor measurements for the first time in the laboratory.
Results show a good agreement with previously reported
spectral effects from outdoor measurements and underline
the importance to consider all three environmental vectors
(irradiance, spectrum and device temperature) for energy
yield focused measurements.
