“…It should withstand external mechanical factors such as rain, snow, and hail (Wang et al, 2020a). If the encapsulation is also on the top-side, i.e., toward the light, it should be easily cleanable and should be enough transparent to allow ample amount of light to reach the actual device (Kempe, 2017). The ability of an encapsulation material can be measured by water vapor transmission rate (WVTR) (Lee et al, 2018b).…”

“…Material selection for encapsulants in PV has changed over time. If during the 1960s and the 1970s the prevailing encapsulant was based on polydimethylsiloxane (PDMS) because of its ultraviolet (UV) and thermal stability [ 3 ], nowadays Ethylene Vinyl Acetate (EVA) and Polyvinyl Butyral (PVB) are the market leaders for glass–backsheet and glass–glass modules, respectively [ 4 ]. The transition between the materials used as encapsulants has taken place mainly because of economic considerations as well as relatively proved reliability, rather than to outstanding EVA material properties.…”

“…In fact, due to their chemical structure, PDMS based materials have less impact on mechanical stress on solar cells than EVA as well as higher bond dissociation energy. An energy of 108 kcal mol −1 is necessary to break Si−O bonds, whereas 83 kcal mol −1 is sufficient to break C−C bonds, typical of polyethylene based materials [ 3 ], such as EVA.…”

“…3 In addition, these materials also tend to have good chemical stability, low toxicity, optical clarity, and oxidative resistance. 4 Because of their versatility, PDMS polymers, typically in the form of high molar mass fluids or cross-linked network elastomers, have been used in many research and commercial applications, such as sealants, microfluidics, potting compounds, electronic encapsulants, 5 microelectromechanical systems (MEMS), 6 insulators, medical devices, 7 and cushions. 8 Unmodified polysiloxane networks generally possess poor mechanical properties, exhibiting low tensile strength and minimal elongation prior to breakage; they tend to be brittle and typically fail easily under shear or compression.…”
