中文摘要
随着光伏(PV)产业的日益成熟,对系统进行特性表征的程度也必须相应提高。紫外荧光(UVF)成像技术是一种有价值、易于实施、高通量且非侵入性的技术,可用于在现场和实验室对光伏组件进行特性表征。然而,紫外荧光成像仍是一项相对较新的技术,光伏行业的许多人仍未意识到其潜力。我们提供了获取、处理和解读紫外荧光图像的指南。我们列出了成像硬件和设置的注意事项,提出了图像处理的建议流程,并详细介绍了紫外荧光图像中显示的特征调查情况。一个包含7190个光伏组件紫外荧光图像的新数据库以及由BrightSpot Automation整理的另一个数据库已公开可用。
English Abstract
As the photovoltaics (PV) industry grows in sophistication, so must the extent to which systems are characterized. UV Fluorescence (UVF) imaging is a valuable, easy-to-perform, high-throughput, nonintrusive technique for characterizing modules in the field and in the lab. However, UVF is still a relatively new technique, and many in the PV industry are still unaware of its potential. We provide a guideline for obtaining, processing, and interpreting UVF images. We have provided a list of considerations for imaging hardware and settings, a suggested pipeline for image processing, and details on a survey of features shown in UVF images. A new database with UVF images of 7190 modules and another database curated by BrightSpot Automation are publicly available.
