摘　　要：针对p型SE-PERC单晶硅太阳电池的氧化现象,通过扫描电子显微镜扫描太阳电池氧化位置和正常位置来分析氧化现象产生原因,然后分析太阳电池氧化区域微观图像上存在的黑点的元素成分,最后给出了预防太阳电池氧化的措施。分析结果显示:太阳电池氧化区域黑点的成分主要为硫元素,而太阳电池氧化实际上是银栅线位置发生硫化导致的。因此减少生产过程中硫元素的引入,可有效预防太阳电池发生氧化。In view of the oxidation phenomenon of p-type SE-PERC mono-Si solar cells,the causes of the oxidation phenomenon are analyzed by scanning the oxidation position and normal position of the solar cells with SEM,and then the element composition of the black spots on the microscopic image of the solar cellsoxidation area is analyzed.Finally,the measures to prevent the oxidation of the solar cells were given.The analysis results show that the main component of black spots in the oxidation area of solar cells is S elements,and the oxidation of solar cells is actually caused by vulcanization at the silver grid line position.Therefore,reducing the introduction of S elements in the production process can effectively prevent oxidation of solar cells.
