Philip Hülsmann, Karl-Anders Weiß and Michael Köhl Temperature-dependent water vapour and oxygen permeation through different polymeric materials used in photovoltaic-modules Progress in Photovoltaics: Research and Applications 22
This work gives a short overview how the permeation process through polymers takes place and how it is influenced by the material properties and ambient conditions. Results of permeation and diffusion measurements for water vapor as well as oxygen are shown for various encapsulation and back sheet materials with special focus on temperature dependency. The results not only demonstrate differences in permeability and temperature dependency for the investigated materials but also show similarities for material groups.
