Towards an accurate and automated characterisation of multi-junction solar cells

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.
