This paper presents the analysis and simulation of the behaviour of triple junction InGaP/GaAs/Ge solar cells designed for space applications when they are illuminated with different light spectra sources. The study involves the utilization of continuous and pulsed light sources and, for this second case, a detailed dynamical analysis by using Pspice® software simulations. Preliminary results show a good agreement between simulation predictions and electrical verification on the Aquarius/SAC-D solar array modules. This work was performed in the frame of a cooperation agreement between the Argentine National Atomic Energy Commission (CNEA) and the Argentine National Commission for Space Activities (CONAE), which is addressed in these first stages to SAOCOM and SAC-D satellites. Thus, the study is particularly oriented to be applied on triple junction (TJ) InGaP/GaAs/Ge solar cells, the cells used in the CONAE satellites solar arrays.
