Advanced Triple Junction Solar Cells with Innovative Assembly for space application: development and flight test

Triple junction solar cells based on InGaP/GaAs/Ge are the baseline for the space application. This paper reports the achievement in terms of development, characterization and in-flight experience for two new concepts of multijunction solar cells developed at CESI and experimented on board of a cubesat developed at Sapienza University: the triple junction solar cells with integral assembly (CTJ-AI) and the triple junction solar cells with enhanced resistance against radiation (CTJ-EOL).
