传送结构对晶硅电池性能影响的研究

Study on the effect of transport structure on the performance of crystalline silicon battery

晶体硅电池生产过程中,需要各种传送结构传输硅片,如滚轮、皮带、吸盘等,这些传送结构直接接触硅片,不可避免的对硅片产生影响,这些影响通常会造成电池片外观或电性能异常而降级降档,因此,对这些降级电池片进行EL(电致发光),显微镜等测试,分析其造成降级的可能原因,对有缺陷的传送结构进行优化改造等,不仅可以解决生产线出现的各类电学和外观异常问题,同时还能保持电池生产效率稳定,提高生产良率,降低生产成本等。

In the production process of crystalline silicon batteries, various transmission structures are required to transmit silicon wafers, such as rollers, belts, suction cups, etc. These transmission structures directly contact the silicon wafers, which will inevitably have an impact on the silicon wafers. These effects will usually cause degradation due to abnormal appearance or electrical performance of the battery wafers. Therefore, EL(electroluminescence), microscope and other tests are carried out on these degraded battery wafers to analyze the possible causes of degradation, and optimize and transform the defective transmission structure, which can not only solves all kinds of electrical and appearance abnormalities in the production line, but also maintains the stability of battery production efficiency, improve production yield and reduces production cost.
