Evaluation of tri-junction solar cells response to electrons and protons of the JUICE specific environment

Degradation of 3G28C Tri-Junction Solar cells from AZUR SPACE has been evaluated for the specific JUICE radiation environment. Data from 1MeV electrons, protons and combined irradiations with in situ measurements is presented on different sets of full scale 3J cells. Analysis is focused on the influence of low temperature, the presence of annealing, and equivalence of damage dose degradation.
