These foils need to be crosslinked during module manufacturing, to enhance their properties. Accurate and reliable methods for the determination of their crosslinking degree are thus very important. In this work, two semi-empirical calorimetric methods are considered and compared to a scientifically sound rheological method used as a reference. The main purpose of this work is to reveal the chemical and physical fundamentals on which the two calorimetric methods are based, to allow for a scientific understanding of their advantages, and limitations. For one of these calorimetric methods, the so-called “Melt-Freeze” method, we have sought for a deeper understanding of the underlying crystallization physics through the use of successive self-nucleation and annealing experiments, which give access to the crystallite size distribution of EVA, and to the influence of crosslinking upon it. © 2017 Wiley Periodicals, Inc.
