摘　　要：基于IEC 61215—2:2021,对光伏组件进行湿热试验和最终稳定试验,考察湿热试验后静置时间和施加机械应力对最终稳定试验后功率的影响。试验结果表明:受硼氧光致衰减(BO-LID)缺陷的影响,本文中的组件在湿热试验后发生较大的功率衰减,有的组件在静置后功率会发生进一步衰减,进行最终稳定试验可使组件功率明显恢复,且功率恢复程度基本不受静置时间或机械应力的影响。Based on IEC 61215—2:2021,damp heat test and final stability test are carried out on photovoltaic modules to investigate the effects of standing time and mechanical stress on the power after final stability.The test results show that under the influence of boron oxygen photoinduced attenuation(bo-lid)defects,the components in this paper have large power attenuation after damp heat test,and some components will further attenuate after standing.The final stability test can significantly restore the component power,and the degree of power recovery is basically not affected by standing time or mechanical stress.
