| 目的 确定太阳电池空间等离子环境下的功率泄漏特性参数。方法 在地面模拟等离子环境下，测量太阳电池阵收集电流随偏置电压的变化规律，再根据计算模型估算太阳电池阵空间环境下的功率泄漏数值。结果 太阳电池收集电流随偏置电压的增大而增大，达到一定阈值后，发生收集电流突变现象，实际测试电流值大于100 mA，功率泄漏百分比大于14.3%。辉光放电伴随收集电流突变过程，等离子体鞘层从太阳电池的导体部分扩展到介质部分；收集电流突变发生后，测量电池暗特性，未发现明显损伤。结论 针对未来高电压大功率太阳电池阵，应采用功率泄漏试验，检验其功率泄漏特性，建议综合考虑多方面的因素规避发生收集电流突变风险。 |

| The work aims to determine the power leakage characteristic parameters of solar cells in space plasma environment. The collected current of solar cell array changing with bias voltage was measured in ground simulated plasma environment, and then the power leakage value of solar cell array in the space environment was estimated according to the calculation model. The collected current of solar cells increased with the increase of bias voltage, and the snapover occurred after reaching certain threshold. The measured current was more than 100 mA and the power leakage percentage was more than 14.3%. With glow discharge accompanied by the snapover, the plasma sheath expanded from the conductor part of solar cells to the dielectric part. When the snapover was over, the dark characteristics of solar cells were measured. No obvious damage was found. For the future high-voltage and high-power solar cell array, the power leakage test should be done to test its power leakage characteristics. It is suggested that comprehensive consideration of various factors should be taken to avoid the risk of snapover. |
