| 目的 针对印制板太阳电池阵在轨长寿命稳定运行需求，对印制板太阳电池阵开展寿命试验验证，研究恶劣的温度环境对太阳电池阵电性能的影响。方法 通过两箱法对试验件开展高低温冲击试验，温度范围为‒90~100 ℃，温度冲击次数不低于3 000次。每隔500次温度冲击后对试验件电压、电流性能进行测试，分析温度冲击对太阳电池阵的影响。结果 各阶段温度冲击试验后，利用电致发光等手段对试验件进行检查，印制板及太阳电池片的表观均正常，无变形、隐裂等异常现象。通过太阳模拟器对试验件进行电性能测试，温度冲击环境对太阳电池电压影响较小，对电流影响较大，会造成电流下降2%~3%。结论 印制板太阳电池阵采用2层印制结构板、小尺寸太阳电池以及可伐互连环节的设计方法，能够满足微小卫星在轨长寿命运行需求，设计时需考虑一定的输出电流裕度设计，提升寿命末期太阳电池阵的可靠性。 |

| In order to meet the long-life and stable operation requirements of printed circuit board solar arrays on orbit, the work aims to carry out life test verification to the printed circuit board solar arrays and study the effect of harsh temperature environment on the electrical performance of solar arrays. The high and low temperature impact test was carried out on the sample by the two-box method in the temperature range of ‒90-100 ℃, and the number of thermal cycling was not less than 3000 times. After every 500 times of thermalcycling, the voltage and current properties of the sample were tested,and the effect of thermalcycling on the solar arrays was analyzed. After the thermal cycling test at each stage, the sample was inspected by EL and other means, and the appearance of the printed circuit board and solar cells were normal. There were no abnormal phenomena such as deformation and hidden cracking. The electrical performance test of the sample was carried out by the solar simulator, the temperature impact environment hadfew effect on the voltage of the solar cells, but had a great impact on the current, which caused the current to drop by 2%-3%. The printed circuit board solar arrays adopt the design method of two-layer printed structural board, small-size solar cells and Kovar interconnection, which can meet the long-life operation requirements of microsatellites on orbit. At last, a certain output current margin design should be considered to improve the reliability of the solar arrays at the end of its life. |
