Characterization of Multijunction Concentrator Solar Cells

Abstract: This chapter summarizes the state of the art in instruments and methods for the characterization of concentrator multijunction (MJ) solar cells (MJSC). The current-voltage characteristic (I-V curve) under illumination and the spectral response or quantum efficiency (QE) are the main properties of a solar cell. The measurement of the I-V curve as a function of light concentration provides the most relevant information on cell performance such as peak efficiency or series resistance losses. Concentrator solar si… Show more

“…We can then conclude that the correction is not needed for the top component cell. However, the M bottom = 0.968 differs from unity by up to 3.2% and hence the X bottom measured by the pseudo‐isotype has to be corrected following Equation . This discrepancy is produced because in the bottom subcell spectral region (from 720 to 1200 nm) some important differences are observed between the simulator and the reference spectra, mainly because of Xe emission spikes and atmospheric light absorption produced by O 2 and H 2 O molecules.…”

“…The 1J structure is used for assessing the angle-dependent characteristics of the nanostructured coating, as with MJSC such characterization is challenging to do correctly and requires more developed instrumentation. 26,27 The actual broadband operation and suitability for MJSCs are then verified with the 4J SCs.…”
