UV-Fluorescence Analysis and comparison with other optical characterization methods

CHEETAH webinar

When illuminating laminated PV modules with UV radiation, often the encapsulant will emit fluorescent radiation in the visible range. The patterns that are thereby exhibited often correlate with cracks in the cells. In the webinar, we will discuss the prerequisite for a measurement system, the best practice for acquiring such images, and discuss the current state of the interpretation of the images and compare the results to other common imaging methods such as thermography or electroluminescence

10:05-11:15	UV-Fluorescence Analysis and comparison with other optical characterization methods	KUBICEK Bernhard
When illuminating laminated PV modules with UV radiation, often the encapsulant  emits fluorescent radiation in the visible range which patterns  can be correlated with cracks in the cells.  In this webinar, Bernhard Kubicek will discuss the use of UV fluorescence spectroscopy analysis in comparison  to other common imaging methods such as thermography or electroluminescence to evaluate  failures in Photovoltaic Modules.   KUBICEK Bernhard Presentation (video FLV) Presentation (YouTube Video) Equipment : Dark lock-in thermography (DLIT) ; UV-Fluorescence Imaging System PV Technologies : PV Module qualification & Reliability
