NOVELTY - The electronic device module comprises an electronic device such as a solar cell (11), a polymeric material placed in intimate contact with a surface of the electronic device, and a glass cover sheet (13). The polymeric material comprises: a polyolefin copolymer having an average (Mv) and a valley temperature (Thc) between the interpolymer and high crystalline fraction such that the average (Mv) for a fraction above the Thc from analytical temperature rising elution fractionation (ATREF) divided by average (Mv) of a whole polymer from ATREF (Mhc/Mp) is less than 1.95.    USE - Used as an electronic device module such as solar cell module or photovoltaic module.    ADVANTAGE - The electronic device module can be easily, rapidly, efficiently and economically manufactured with high mechanical strength, durability and flexibility, light weight, long lifespan, good transparency and increased electrical resistance and thermal creep resistance and without moisture and premature crosslinkage.    DETAILED DESCRIPTION - The electronic device module comprises an electronic device such as a solar cell (11), a polymeric material placed in intimate contact with a surface of the electronic device, and a glass cover sheet (13). The polymeric material comprises: a polyolefin copolymer having an average (Mv) and a valley temperature (Thc) between the interpolymer and high crystalline fraction such that the average (Mv) for a fraction above the Thc from analytical temperature rising elution fractionation (ATREF) divided by average (Mv) of a whole polymer from ATREF (Mhc/Mp) is less than 1.95, where the copolymer has a composition distribution branch index (CDBI) of less than 60%; optionally a vinyl silane; optionally a free radical initiator or a photoinitiator such as a peroxide present in an amount of 0.05 wt.% based on a weight of the copolymer; optionally a co-agent present in an amount of 0.05 wt.% based upon the weight of the copolymer; and a scorch inhibitor present in an amount of 0.01-1.7 wt.%, and material is present in the form of a monolayer film placed in intimate contact with a face surface of the electronic device.
