摘要(Abstract)：

为分析不同体积电阻率的封装胶膜对光伏组件漏电流及抗PID性能的影响，首先挑选了不同分子结构的封装胶膜，测试其体积电阻率；再分别采用不同类型的封装胶膜封装成光伏组件，通过实验设备模拟户外高温高湿恶劣环境，对比了不同类型封装胶膜封装的光伏组件的漏电流及抗PID性能差异。研究结果表明：在相同实验条件(实验箱中环境温度85℃、相对湿度85%，外接-1000 V直流电源，测试时间96 h)下，采用不同分子结构封装胶膜封装的光伏组件表现出不同的抗PID性能；封装胶膜的体积电阻率越高，水蒸气透过率越低，对应的光伏组件的漏电流绝对值越低，光伏组件的抗PID性能越好；光伏组件应用于高温高湿环境中时应优先选择共聚烯烃(POE)封装胶膜。
