NOVELTY - An electronic device module (10) comprises at least one electronic device, and a polymeric material in intimate contact with at least one surface of the electronic device, where the polymeric material contains an ethylene-based polymer composition having a Comonomer Distribution Constant greater than 45 (preferably greater than 50, especially greater than 95), and as high as 400 (preferably as high as 200); optionally vinyl silane (at least 0.1 wt.%); optionally, a free radical initiator (at least 0.05 wt.%); and optionally co-agent (at least 0.05 wt.%).    USE - As an electronic device module (claimed) e.g. solar cell module for use in architectural applications.    ADVANTAGE - The electronic device module protects the device from exposure to the outside environment, e.g. moisture and air, particularly over long periods of time; protects against mechanical shock; provides strong adhesion to the electronic device and substrates; provides easy processing, including sealing; exhibits excellent resistance to thermal creep at greater than or equal to 90 degrees C; exhibits good transparency, particularly in applications in which light or other electromagnetic radiation is important, e.g. solar cell modules; exhibits short cure times with protection of the electronic device from mechanical stress resulting from polymer shrinkage during cure; exhibits high electrical resistance with little, if any, electrical conductance; and is prepared at low cost.    DETAILED DESCRIPTION - An electronic device module (10) comprises at least one electronic device, and a polymeric material in intimate contact with at least one surface of the electronic device, where the polymeric material contains an ethylene-based polymer composition having a Comonomer Distribution Constant greater than 45 (preferably greater than 50, especially greater than 95), and as high as 400 (preferably as high as 200), where the composition has less than 120 total unsaturation unit/1000000C, preferably the ethylene-based polymer compositions comprise up to 3 long chain branches/1000C (preferably 0.01-3 long chain branches/1000C), can have a Zero-shear viscosity ratio (ZSVR) of at least 2, can further comprise less than 20 vinylidene unsaturation unit/1000000C, can have a bimodal molecular weight distribution (MWD) or a multi-modal MWD, can have a comonomer distribution profile comprising a mono or bimodal distribution of 35-120 degrees C, excluding purge, can comprise a weight average molecular weight (Mw) of 17000-220000; optionally vinyl silane (at least 0.1 wt.%); optionally, a free radical initiator (at least 0.05 wt.%); and optionally co-agent (at least 0.05 wt.%). The electronic device is a solar cell.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic diagram of an electronic device module i.e. a rigid photovoltaic (PV) module.
