“…Previous studies on the performance of solar cells under LILT conditions have reported fill factor anomalies and the decrease of cell efficiencies [1][2][3][4][5][6][7][8]. Most of these effects have not yet been fully understood.…”

“…1. The difference in cell design ("Standard" vs. "LILT") is mainly related to a modification of the front side metallisation aiming at mitigating the so-called "flat spot effect" [2][3][4]. However, as it was demonstrated in a precursor activity also the cells with standard design did not show any flat spot effect [5].…”

The paper provides an overview of the current status of several technical development activities initiated by the European Space Agency (ESA) to support the JUICE mission to the Jovian system. First of all, the qualification status of the solar cells to be used in the JUICE mission will be reported. Then, the conclusions from a dedicated activity aiming at assessing the potential degradation of triple-junction solar cells upon primary discharges will be discussed. Finally, the results on the coupon tests currently running at ESA will be presented. The coupons consist of representative solar cell assemblies including coverglasses with a conductive Indium Tin Oxide (ITO) layer. Dedicated coverglass grounding technologies are tested on the coupons which connect the conductive coverglass surfaces to the panel ground. It will be shown how the resistivity of the materials used in the coupons evolves upon submission to extreme thermal cycles.

“…However, the understanding of their behavior under particle irradiation at low temperature is still in infancy. Because of the difficulty to perform irradiation testing at low temperature followed by in‐situ electrical data acquisition under solar illumination, this understanding has been deduced from low temperature measurements performed after room temperature irradiation . With the exception of 1 attempt, the only studies of low temperature irradiation with in‐situ measurements have been performed on TJ cells produced by AZUR SPACE …”

To understand the influence of proton irradiation on lattice-matched GaInP/GaAs/Ge triple junction (TJ) solar cells under low intensity, low temperature (LILT) conditions, we investigated electrical behaviors of top, middle, and bottom component cells together with TJ cells under these conditions. Proton irradiations with energies of 1 MeV and fluences ranging from 2 × 10 10 to 1.6 × 10 12 cm −2 were performed at temperatures ranging from 100 to 300 K. Our study reveals that any of the 3 subcells can become the current limiting cell in the TJ cell, depending on temperature and fluence. In particular, remarkable degradation of the bottom cell at low temperature can make this subcell the current limiting in a TJ cell even for limited fluences. The results indicate that the defect distribution is non-uniform for low temperature irradiation.
