摘要
月尘在月球探测器太阳电池阵表面的累积将会导致其输出功率下降甚至功能失效。近年来,电帘除尘方法被认为是月尘清除防护的有效手段。文章实验研究了月尘累积对三结砷化镓太阳电池性能影响,拟合得到了月尘累积质量与太阳电池相对输出功率的数学模型;利用电帘除尘装置,研究了不同月尘累积质量下电帘的除尘效率。研究结果表明,6 mg/cm2月尘累积质量是太阳电池阵电帘除尘装置启动的最佳工作条件。该研究成果可为开发具有自适应除尘能力的太阳电池阵提供技术支持。
The solar array output power will be decreased, which will lead to its failure, when the lunar dust is accumulated on the surface of the solar array. In recent years, the electric curtain dust removal method is considered as an effective way for the lunar dust protection. In this paper, the performance of the triple-junction gallium arsenide solar cell is analyzed through experiments of the lunar dust accumulation on the solar cell, and a trend exponential fitting function between the relative output power and the dust deposition mass is obtained. Furthermore, the dust removal efficiency of the electric curtain for different amounts of lunar dust accumulation mass is studied. The results show that the optimum operating point of the electric curtain dust removal device is 6 mg/cm2. The research provides a technical support for the solar array with adaptive dust removal capacity.
