摘　　要：系统研究了太阳能电池盖片玻璃经离子交换增强(化学钢化)后的机械性能、透光率以及离子束轰击对盖片性能的影响。分别利用动态力学分析仪(DMA)、光学显微镜、扫描电镜(SEM)、紫外-可见分光光度计和硬度仪等对盖片玻璃的力学性能、表面形貌、透光率、硬度等性能进行了测试。结果表明,经离子交换增强后的盖片玻璃,弯曲强度最大可以提高约4倍;且在受到离子束轰击时的损伤以及透光率下降的程度都小于原片玻璃,说明化学钢化玻璃具有较好的耐离子束轰击的能力。因此化学钢化能提高太阳能电池长期工作的可靠性,对提高太阳能电池的使用效率及寿命具有实际意义。The mechanical property, light transmittance of ion exchange strengthened solar cell cover glass and the effect of ion beam bombardment on its properties are investigated by dynamic mechanical analyser （DMA）, microscope, SEM, UV/visible spectrophotometer and micro hardness instrument respectively. The results show that the flexural strength of ion exchange strengthened cover glass increases about 4 times at the most than that of as-received one. The damage and the decrement of light transmittance of ion exchange strengthened cover glass are much lower than that of as-received one after ion beam bombardment, which demonstrates that ion exchanged solar cell cover glass has better resistance to ion beam bombardment. Consequently, ion exchange strengthened cover glass can increase the reliability of solar cell, which can improve service efficiency and prolong the life of solar cell.
