ABSTRACT: One of
the most important parameter used for the evaluation of the energy rating of PV
modules is, their spectral responsivities which are the measure of electrical
performance parameters per incident solar radiation. In this work, spectral
responsivity measurements of a mono-crystalline, a poly-crystalline, a CIGS
thin film and a bifacial module were measured using xenon-based
flash type solar simulator system and a set of band pass filters. For the comprehensive characterization of parameters that may
influence the spectral responsivity
measurements, initially the simulator system was characterized both
optically and thermally according to the IEC60904-9 and IEC60891 standard
requirements. The optical characterizations in terms of spectral match, spatial
non-uniformity and temporal instability indicate that the measured results
(~3.0%, ~0.30% and ~0.20%) according to the IEC 60904-9 standard’s
classification requirements correspond to A+A+A+ classes. Moreover, thermal
characterizations in terms of the temperature uniformity show that over the 2 × 2 m area temperature uniformity of simulator system’s light distribution
(1ºC) is almost two times better
than the IEC 60891 standard requirements (±2ºC). Next, PV modules
were electrically stabilized according to the IEC 61215-2 standard
requirement’s (stability test) to reduce the fluctuations in their electrical
performance parameters. Then, using the band pass filters, temperature
controlled xenon-based solar simulator system and a reference PV module of the spectral responsivity of PV modules were measured from 400 nm to 1100
nm with 50 nm steps with relative uncertainty of 10-3 level.
