Abstract: An electronic device module comprises: A. At least one electronic device, e.g., a solar cell, and B. A polymeric material in intimate contact with at least one surface of the electronic device, the polymeric material comprising an ethylene multi-block copolymer. Typically, the polyolefin material is an ethylene multi-block copolymer with a density of less than about 0.90 grams per cubic centimeter (g/cc). The polymeric material can fully encapsulate the electronic device, or it can be laminated to one face surface of the device. Optionally, the polymeric material can further comprise a scorch inhibitor, and the copolymer can remain uncrosslinked or it can be crosslinked.
