Nondestructive Testing for Bonding Defects of Space Solar Cells

摘要: 针对空间用太阳电池的胶接缺陷开展了无损检测方法的研究，分别采用红外热波检测和空气耦合超声检测的方法进行了试验，对检测结果进行了对比分析。结果表明，红外热波检测和空气耦合超声检测均能检测出空间用太阳电池胶接的主要缺陷，其中红外热波方法的检测结果不受背面基板结构的干扰，检测速度更快。

Abstract: The research on nondestructive testing for bonding defects of solar cells is presented in this paper. The experiments for testing of bonding defects were respectively carried out by infrared thermal wave testing and air-coupled ultrasonic testing, and the testing results were compared and analyzed. The research shows that the bonding defects of solar cells can be detected by infrared thermal wave testing and air coupled ultrasonic testing, while infrared thermal wave testing shows more rapid test speed and is undisturbed by the substrate on the rear of solar cells.
