A theoretical approach of automated characterisation
of single as well as multi-junction
solar cells has been developed. The method
will be implemented in CREST’s measurement
system. It delivers not only I-V characteristics
at reference spectrum but also absolute spectral
response of the test cell. Thus it opens the
way for inline spectral response measurements.
The method requires nothing more than
a multisource solar simulator, some basic information
about the test cell and a calibrated
reference cell.
Single- and multi-junction measurement procedures
are briefly reviewed; the automatic
measurement approach is explained and underlined
with real and simulation results.
