摘要
在构建三结GaAs太阳电池模型的基础上,模拟分析不同能量质子辐照下中电池GaAs的性能衰退,对三结GaAs电池在轨服役评估具有重要意义。结合质子与电池靶材发生的相互作用,建立一种将微观损伤机理与宏观电池性能变化相结合的电池辐照损伤评价方法。结果表明,在三结GaAs太阳电池中,40 keV能量的质子辐照对中电池的影响最小;100和150 keV能量的质子辐照主要对中电池基区造成影响,导致电池性能一定程度上的衰退;70 keV能量的质子辐照对于中电池结区的影响最大,从而导致量子效率QE和并联电阻Rsh的变化最为明显。
The irradiation simulation analysis of protons with different energy for three junction GaAs solar cells is of great significance to the on orbit service evaluation of the cells.In this study,a three junction GaAs solar cell model is constructed,and the performance degradation of the cell under proton irradiation with different energy is simulated;Combined with the interaction between proton and battery target,a battery irradiation damage evaluation method combining micro damage mechanism with macro battery performance change was established.The results show that in the three junction GaAs battery,the proton irradiation with 70 keV energy has the greatest influence on the junction region of the battery,resulting in the most obvious changes in quantum efficiency QE and parallel resistance.Proton irradiation with 40 keV energy has the least impact on the medium battery,while proton irradiation with 100 keV and 150 keV energy mainly affects the base area of the medium battery,resulting in the most obvious change of series resistance of the battery.
