PV Module Lamination Durability
Abstract
Lifetime of terrestrial PV modules is determined not by limits of the photovoltaic process but by ingression of moisture into the module laminate. To avoid (or at least to limit) moisture ingression an adequate sealing at the module edges is very helpful, but also a good adhesion of the laminate layers is necessary. This paper addresses the adhesion quality. Adhesion of a standard PV module lamination is consisting of the sequence glass-EVA-cell-EVA-glass or glass-EVA-cell-EVA-backsheet. The adhesion quality depends mainly on:
