Abstract

The JUICE (JUpiter ICy moon Explorer) mission is characterized by a severe environmental condition, as the spacecraft will mainly operate in the Jovian region of the solar system. Low intensity, low temperatures and high radiation doses are the challenging factors for the solar array and especially for the photovoltaic assembly. Following a technology research program [1], the $3\mathrm{G}28$ bare solar cell by Azur Space has been selected; moreover, dedicated acceptance criteria were defined to screen the devices for highest and predictable performance under the harsh Jovian condition. Leonardo has then started a pre-qualification at solar cell and protection diode assembly level (cell and diode with coverglass and interconnectors). This pre-qualification identified the technology to be finally tested in accordance to the relevant ECSS standard, specifically including also a test in low intensity low temperature (LILT) condition also for the full-scale photovoltaic assembly qualification model.

JUICE光伏组件的低强度低温/暗测量活动-从太阳能电池到全尺寸合格模型

JUICE(木星冰月探测器)任务的特点是恶劣的环境条件，因为航天器将主要在太阳系的木星区域运行。低强度、低温和高辐射剂量是太阳能电池阵列尤其是光伏组件面临的挑战。根据技术研究计划[1]，Azur Space公司的3\ mathm {G}28$裸太阳能电池已被选中;此外，还定义了专门的验收标准，以筛选设备在恶劣的木星条件下的最高和可预测的性能。莱昂纳多随后开始了太阳能电池和保护二极管组装级的资格预审(电池和二极管与覆盖玻璃和互连器)。这次资格预审确定了根据相关ECSS标准进行最终测试的技术，具体包括在低强度低温(LILT)条件下的测试，以及全尺寸光伏组件资格模型。
