Abstract
Official abstract text for this publication.
This invention relates to photovoltaic modules wherein a polyethylene composition is used as an alternative, in whole or in part, to traditional ethylene vinyl acetate (EVA) resins in at least one layer. The polyethylene compositions are especially useful in the encapsulant and/or backsheet layers of photovoltaic modules. The polyethylene compositions comprise units derived from at least one C 4 to C 6 alpha-olefin comonomer, and have densities of 0.86 g/cm 3 to 0.91 g/cm 3 .
First claim
Opening claim text (preview).
1 . A photovoltaic module having a layer comprising a polyethylene composition, wherein said polyethylene composition comprises: a. 50.0 wt % to 99.5 wt % of polymer units derived from ethylene, and b. 0.5 wt % to 50.0 wt % of polymer units derived from at least one C 4 to C 6 alpha-olefin comonomer, based on the total weight of said polyethylene composition, and said polyethylene composition has a density, in accordance with ASTM D1505 at 23° C., of 0.86 g/cm 3 to 0.91 g/cm 3 .…
