Moisture Barrier, Mechanical, and Thermal Properties of PDMS-PIB Blends for Solar Photovoltaic (PV) Module Encapsulant

In this study, we have investigated and screened the performance of our adhesive material that does not require an edge seal. This paper primarily focuses on the synergistic properties of PDMS and PIB via physical blending. The UV blocking nature of PDMS and the high adhesion and superior barrier property of PIB were considered. Our polymer blend also maintains the transparency in the visible range. This polymer blends were performed with several kinds of material characterizations such as morphology, hardness, thermal profiles, moisture ingress properties, and adhesion strength. This paper serves to provide discussions on preliminary evaluations for transparent PV module encapsulant.
