研究目的
To develop and qualify a photovoltaic assembly (PVA) for the JUICE mission that can withstand the demanding environmental conditions of the Jovian system, including low temperature, low sun intensity, and high radiation levels.
研究成果
Leonardo PVA processes and integration methods have been successfully tested, demonstrating suitability of adopted solutions for the JUICE mission. All combinations have been deeply tested and verified, giving the go-ahead for FM panel manufacturing.
研究不足
The outgassing rate monitoring during bakeout was not possible due to the high floor level of the outgassing related to the chamber. The measurement at low intensity was affected by higher uncertainty.
1：Experimental Design and Method Selection:
The development process involved pre-qualification tests at coupon level and full qualification tests at Qualification Model (QM) level.
2：Sample Selection and Data Sources:
Several coupons were manufactured and tested to identify the proper technology for the JUICE mission.
3：List of Experimental Equipment and Materials:
Included 3G28 bare solar cell by Azur Space, external silicon protection diode by Azur space, CMG protection cover glass by QioptiQ, and various adhesives and interconnector materials.
4：Experimental Procedures and Operational Workflow:
The QM panel was subjected to a series of tests including bake out, LILT measurement, cryogenic cycling, and electrical checks.
5：Data Analysis Methods:
Electrical monitoring during cycling, visual inspection, and flasher test results were used to assess performance and identify any degradation.
