激光对卫星太阳能电池的毁伤效果研究

Ablation damage caused by laser beam to solar cell of satellite

  • 摘要: 分析了激光对目标的毁伤机理,通过变功率等时长激光照射、改变入射角度激光照射、太阳能电池破坏等试验,对激光干扰与毁伤效果进行了分析。随着激光照射时间的加长,太阳能电池的输出出现的不同变化趋势与入射激光的功率密度密切相关。在低于某一激光功率密度阈值时,激光照射引起的太阳能电池输出下降是暂时的,是可恢复的,低功率密度激光对太阳能电池的干扰和破坏主要是激光引起的热效应。当干扰激光功率密度足够高时,可对太阳能电池造成物理特性变化,从而产生永久性不可恢复的损伤。

     

    Abstract: The ablation damage caused by laser beam to targets is investigated. The laser disturbance and ablation damage principles are analyzed by the aid of the isochronal irradiation at different power, laser irradiation at different incident angle and solar cell destructive tests. The variation of the solar cell output power with the laser irradiation time is related with the power density of incident beam. The power density inferior to the threshold may leads a decline of solar cell output, which is restorable and temporary. The consequential ablation damage is caused by heat effect of laser. In contrast, the power density in great magnitude may lead a serious ablation damage that is not restorable.
