Paper Abstract

The main objective to study the mechanisms of moisture penetration on glass/pvb/glass laminates comes from the request to improve PV module reliability that uses PVB as encapsulant film. In order to provide modeling, extensive experimental work was performed to understand the eventual preferential channels for moisture penetration. This covers different edge deletion methods (etching, sand blasting) and internal topographies (bus bars, laser scribes). The moisture content is determined by punctual IR Spectroscopy and the moisture penetration induced by standard Damp Heat.
