Spectrometric characterization for triple‐junction solar cells
Abstract: Spectrometric characterization allows for accurate determination of the current
matching point and investigation of sub-cell properties of multi-junction solar
cells. It is widely used for dual-junction solar cells. Although the concept is suggested for triple-junction solar cells, it is only applied for the variation of two
sub-cells. In this work, the applicability and evaluation procedure for a systematic
variation of all three sub-cells of a triple-junction solar cell are presented. Clearly
defined measurement conditions are derived which allow for meaningful characterization and comparisons of different triple-junction devices. The presented
procedure is exemplarily tested on a III–V on silicon triple-junction solar cell using
an light-emitting diode-based solar simulator where all needed spectral conditions
can be calculated in advance and accordingly adjusted. Spectral conditions around
the air mass 1.5 global spectrum are chosen and a fit routine to determine the
current matching point from the discrete measurement points is proposed and
validated by a measurement with a higher resolution around the current matching
point. Finally, it is shown that the spectral conditions applied during the measurement also reflect outdoor conditions. This highlights the relevance of the
presented procedure beyond the determination of the current-matching conditions
