EL测试在光伏太阳能电池检测中的应用

摘要

In order to meet the higher requirements of customers on the capability of solar modules, the Electroluminescence （EL） test in the solar cells could effected to detect raw materials defects. By using EL test in laminated laying and solar modules, defects, which caused by the unreasonable parameter settings in production process and from human factors, could be controlled. So the quality of solar modules could be guaranteed by eliminating the defects before leaving the factory. Meanwhile, the manufacturing technique of solar ceils and modules could be refined and improved by analysising EL images. It could also provide a constructive guide on the production of solar cells.%为了满足客户对太阳能电池组件性能的更高要求，通过对电池片的EL测试，从来料方面进行把关，通过对层压敷设件和组件的EL测试，能够合理的控制由于工艺参数设置不当和人为因素引起的组件不良缺陷，从而能够将问题消灭在组件出厂之前，保证组件质量。同时，通过分析EL图像，也有助于完善和改进电池片以及组件的生产工艺，对太阳能电池的生产有重要指导意义。
