Abstract

The disclosure relates to an encapsulant film for photovoltaic modules comprising: POE and at least one hydrogenated block copolymer. The hydrogenated block copolymer is selected from: a multi-arm hydrogenated block copolymer (MABC) having a structure of ("R")<n>X, X is residue of a coupling agent and n = 4 to 20, a hydrogenated styrenic block copolymer (HSBC), and combinations thereof. The HSBC contains at least one block "R" and at least one block "S." Each block "S" is composed of vinyl aromatic units, and each block "R" is composed of hydrogenated diene units. The HSBC has a vinyl aromatic unit (VAC) content of < 40 wt.%. The encapsulant film after curing has a static friction coefficient of > 0.39, and a dynamic friction coefficient of > 0.40. The encapsulant film provides improved anti-slip properties, and a balance of transparency and mechanical properties.
