摘要

JAXA’s approach to realizing a high specific power solar paddle by utilizing thin-film III-V multijunctionsolar cells is introduced. Thin-film cells laminated with thin and transparent sustaining materials have beennamed a “Space Solar Sheet (SSS).” Development of the first-generation SSS (SSS-1) was completed in 2010. ThinfilmInGaP/GaAs dual-junction (TF2J) cells are used as solar cells in the SSS-1. The AM0 efficiency of the TF2Jcells is ~25%. Two types of lamination structure for the active side are employed: one uses transparent films, and theother has a conventional configuration using a coverglass. The specific power of the SSS-1 is 0.4-0.5 W/g.Characterization and environmental qualification tests have confirmed their space quality and life at more than 5years in the LEO environment (the film type) and 10 years in the GEO environment (the coverglass type). Thedevelopment of lightweight solar panels has been conducted simultaneously. By adopting frames and hinges made ofCFRP tube and aluminum, thin and also lightweight panels are realized. The total thickness of the five stacked panelsis as thin as 7 cm, which provide us very low stowage volume. Studies on diagnosis technologies for subcelldegradation analysis and solar panel inspection are underway.
