19 August 2010 Glass-encapsulant interface characterization following temperature and humidity exposure
Author Affiliations +
The ability to optimize and consistently control the properties of the polymer-glass interface in thin film PV laminates in an important aspect of module reliability. Using variable rate peel delamination methods developed to isolate the encapsulant/glass interface, ion migration and interfacial chemistry have been studied following temperature and humidity exposure. In this presentation we will review quantitative AFM (Atomic Force Microscopy) and XPS (X-ray Photoelectron Spectroscopy) analyses linking failure modes with interfacial chemistry.
