Abstract
Although the technical and economic properties of the standard polymer materials used in photovoltaic (PV) modules, EVA, ethylene-vinyl-acetate encapsulant and fluorine-containing PET,
polyethylene-terephthalate backsheet, are satisfactory, more sustainable PO (polyolefin) based encapsulants and backsheets have been developed. The long-term stability of new materials in
terms of electrical performance and reliability of the modules is tested and evaluated using accelerated aging tests and degradation modelling. Based on experiments, the influence of the type of
encapsulant and backsheet (i) on the electrical output power of PV test modules and (ii) on the aging-related electrical and material degradation under artificial stress was estimated using statistical modelling approaches. Two-way variance analysis (ANOVA) indicates significant effects for encapsulant, backsheet, and their combination on the initial power PMPP. Mixed-effects modelling of the degradation rates upon damp heat exposure clearly shows that the one for modules with EVA is significantly larger than that using polyolefin encapsulants. The derived relations are aimed to provide valuable input for innovative material developments as well as predictive maintenance specifications.
