太阳电池组件I-V特性曲线异常

为了正确评价太阳电池组件I-V特性曲线异常现象,通过对多个太阳电池I-V特性曲线组合的分析,分别探讨了安装和不安装旁路二极管的太阳电池组件的I-V特性曲线产生异常(台阶)的原因,分析了I-V特性曲线异常对热斑效应的影响,评价了I-V特性曲线异常与产品质量之间的关系,给出了太阳电池组件产生I-V特性曲线异常必须具备的三个条件,因此提出了减少和改善I-V特性曲线异常的方法。

Analysis of I-V curve abnormity of solar module

I-V curve abnormity of solar module was evaluated in this paper. Through the analysis of the combined I-V curves of a couple of solar cells, the reasons for I-V curve abnormity of solar module with and without bypass diodes were discussed respectively, the influence of I-V curve abnormity of solar module on hot spot was construed, and the relationship of I-V curve abnormity of solar module with product quality was judged. Three terms that causes the I-V curve abnormity of solar module and the way to improve...
