摘要
组件在使用中输出功率会逐渐下降,通过恒温恒湿、高低温交变等模拟试验,进行组件的环境测试和安全测试,通过电致成像、红外热像、电性能测试分析隐裂对组件的影响。设计对比试验,利用统计数据拟合组件在断裂的情况下造成的输出功率损失和实际结果十分接近,得出隐裂对光伏组件输出功率的影响,对于改进组件工艺提供了依据。
In practical application, output power of the modules will decrease gradually. Many experiments were made, i.e. damp-heat test, thermal cycling test, environmental test and safety test, EL images, infrared thermal images, electrical performance test, and etc to see the impact of hidden crack to the modules. A designed comparison experiment was made. The result shows that output loss caused at breaking of the fitting module made based on statistics data is very much close to the output loss of modules in practical life. Therefore, we can see the impact of hidden crack to the output of the modules and provide a theoretical base for improving module technology.
