NOVELTY - A solar cell pre-lamination assembly comprises a terionomer multilayer film or sheet and a solar cell component formed of one or several electronically interconnected solar cells, where the solar cell component has a light-receiving side that faces a light source and a back side that is opposite from the light source.    USE - As solar cell pre-lamination assembly used to produce a solar cell module (claimed).    ADVANTAGE - The terionomer multilayer film or sheet possess enhanced transparency; and has improved adhesion strength to other laminate layers, such as glass, especially after severe environmental aging, such as after being kept under high temperature (e.g. greater than or equal to 75 degrees C) and high humidity (e.g. relative humidity of greater than or equal to 85%) conditions for a prolonged period of time (e.g. greater than or equal to 750 hours). The addition of the high melting point polymer in the multilayer film or sheet provides improved thermal resistance.    DETAILED DESCRIPTION - A solar cell pre-lamination assembly comprises a terionomer multilayer film or sheet and a solar cell component formed of one or several electronically interconnected solar cells, where the solar cell component has a light-receiving side that faces a light source and a back side that is opposite from the light source. The terionomer multilayer film or sheet comprises a first surface sub-layer, a second surface sub-layer, and optionally at least one inner sub-layers sandwiched between the first and second surface sub-layers. The first surface sub-layer of the terionomer multilayer film or sheet comprises a terionomer. The second surface sub-layer of the terionomer multilayer film or sheet, and/or at least one of the optional inner sub-layer(s) of the terionomer multilayer film or sheet, comprises a high melting point polymer. The terionomer is derived from an acid terpolymer that is 5-90% neutralized with at least one metal ions, based on the total carboxylic acid content of the acid terpolymer, and comprises repeat units derived from an alpha -olefin, an alpha , beta -ethylenically unsaturated 3-8C carboxylic acid (5-15 wt.%), and an alpha , beta -ethylenically unsaturated 4-12C carboxylic acid ester (15-40 wt.%), based on the total weight of the acid terpolymer. The high melting point polymer has a melting point of at least 80 degrees C. An INDEPENDENT CLAIM is included for a process involving: providing a solar cell pre-lamination assembly and laminating the assembly to form a solar cell module.
