摘要

近年来，紫外荧光技术在光伏组件缺陷检测领域的应用得到了广泛的应用。本文研究了紫外光照射下模块封装材料中荧光团的形成速率。我们观察到包封剂可见光透射率的降低与紫外线荧光强度之间存在相关性。这种相关性可以通过荧光测量来估计发黄引起的功率损失。

Ultraviolet fluorescence of ethylene-vinyl acetate in photovoltaic modules as estimation tool for yellowing and power loss

The potential of ultraviolet (UV) fluorescence as a field technique for photovoltaic module defect detection was demonstrated recently. Here we study the formation rate of the fluorophores in module encapsulating material under UV illumination. We observe a correlation between the decrease in visible light transmission of the encapsulant and UV fluorescence intensity. This correlation allows estimating the yellowing-induced power loss via fluorescence measurements.
