Abstract
An encapsulant material includes a layer of metallocene polyethylene disposed between two layers of ionomer. More specifically, the layer of metallocene polyethylene is disposed adjacent a rear surface of the first ionomer layer, and a second layer of ionomer is disposed adjacent a rear surface of the layer of metallocene polyethylene. The encapsulant material can be used in solar cell module and laminated glass applications.
Claims21
An encapsulant material comprising:
- an outer layer of ionomer;
- an inner layer of metallocene polyethylene disposed adjacent a rear surface of the first layer;
- and
- a second outer layer of ionomer disposed adjacent a rear surface of the layer of metallocene polyethylene, wherein each of the first layer of ionomer and the second layer of ionomer have at least 4% free acid content by weight.
