“…In the last thiry years researches about properties of interlayer used in lamination industry started to arise. Many researches have been conducted about deformation of interlayer, effect of viscoelastic and hyperelastic properties on the behavior of interlayer [ 37 , 38 ].Effects of environmental conditions, heat and different interlayer types like PVB, EVA and SG on the behavior of laminated glass unit has been extensively studied [ [39] , [40] , [41] , [42] ].…”

“…Moreover, considering that BIPV products typically operate at higher temperatures, 41–46 or are more frequently subjected to shading with the possibility of hot spots, 47 the proposed procedure has been framed in the application field of IEC TS 63126 48 which defines additional testing requirements for PV modules operating at higher module temperatures. Even low temperatures may have an effect due to encapsulant glass transition temperature 49 or in relation to the thermal breakage of the glass, 50 as well as the presence of solar cells and hotspots resulting in adhesion between plastic and glass 19 . For these reasons, temperature scenarios have been defined as boundary conditions of the impact test procedure to identify LS under operating and exceptional conditions.…”

Building integrated photovoltaics (BIPV) is progressively achieving an advanced level of technical maturity and considerable market penetration. In the last kilometre for considerable market implementation, major challenges are today mostly related to improving cost-effectiveness and product reliability. BIPV multifunctional products are still framed in complex and sometimes unclear qualification processes, in the grey area between electrotechnical and construction sectors, impacting commercialization and users' confidence. The EN 50583 part 1 and part 2 standards today represent the main regulatory framework in Europe for BIPV. However, acts in force for product certification, in the construction and electrical sectors, in most national and local contexts are not yet harmonized for BIPV and imply wide margins of interpretation. The product's qualification in the EU is therefore based on electrical standards for photovoltaics modules or, on the other hand, on standards for construction products. To overcome some of these barriers and challenges, the authors propose a newly developed procedure for testing the impact resistance of BIPV products, introducing a performance-based approach with the goal of combining building and electrical-related limit states and responding to the need for a harmonized assessment to ensure the product's safety in use. The methodology and preliminary findings resulting from the application of real test cases, taking also into account the effect of temperature, are presented and analysed. As a result, it is envisaged that the implementation will help operators and prospective normative upgrades, ensuring more outstanding product quality for BIPV's market and driving towards a drop in life cycle costs.

It is known that weathering action has a significant impact on polymer interlayer materials, and previous studies have evaluated certain aspects of weathering such as temperature, humidity, and UV radiation. In this paper, the environmental effect on the mechanical properties of the virgin and cured/processed polymer interlayer materials will be studied. Three polymer interlayer materials were focused, i.e., Polyvinyl butyral (PVB), Ethylene-vinyl acetate (EVA), and Ionomer (SG), due to their industrial interest. Testing setups were designed to apply the environmental effects and perform mechanical testing on the polymeric materials. Four environmental effects were studied, including water submersion (E1), constant high temperature (E2), cyclic temperature with low relative humidity (E3), cyclic temperature, and relative humidity (E4). After the exposure of these materials to these environmental effects, the samples were prepared and mechanically tested. Uniaxial tests were performed under static and high strain rates (around 45−1). It was found that under dynamic load, the properties of EVA such as the strength, maximum strain, and the toughness were not significantly affected by the environmental effects. SG5000 properties were significantly affected.
