Demonstration of Ultra-Thin GaAs/Ge based multi-junction solar cells

Objectives

To check the interest to use ultrathin GaAs multi-junction cell technology on solar array, at system level, versus

  • Mechanical solar array architecture type ( rigid or flexible)
  • Cell characteristics and best estimated performances
  • Cell technologies roadmap.

To pre-develop cell assembly technology with GaAs multi-junction solar cells on 20 µm and 80 µm Ge, and test at SCA level and at coupon level.

Current Status

Completion of Final Review in October 2014.

NEOSAT program is already in the next development phase at cell level, solar array level and at system level.
