The scope of the activity is to define the flight Thin Film Solar Cell Demonstration Module and to breadboard critical elements.
Development of space worthy solar cells in CIS technology Integration of these cells into a spacecraft solar array breadboard.
Providing of a European supply of thin film solar cell technology.
Phase 1: Definition of Demonstration Module / Design of breadboard
Phase 2: Manufacturing of Breadboard / tests / update definition
Breadboard of 840 to 500 mmÂ² size manufactured with 129 solar cells in two strings. Measurements of electrical characteristics (efficiency under sunlight, under test setup, insulation resistance of solar network against ground, resistance over electrical network). First campaign of thermal-vacuum cycling has been performed. Acoustic test between 2 dummy panels representing rigid solar panels has been successfully overcome (147 dB overall excitation). Ready to start with 2nd thermal cycling test campaign.
