NOVELTY - A solar cell pre-lamination assembly comprises: a terionomer multilayer film or sheet and a solar cell component formed of several of electronically interconnected solar cells. The terionomer multilayer film or sheet comprises a first surface sub-layer, second surface sub-layer and optionally at least one inner sub-layer sandwiched between the first and second surface sub-layers. The first surface sub-layer comprises terionomer. The second surface sub-layer and/or at least one of the optional inner sub-layer(s) comprise a high melting point polymer.    USE - In preparing solar cell module (claimed) e.g. single crystal silicon solar cells, polycrystal silicon solar cells, microcrystal silicon solar cells, amorphous silicon based solar cells, copper indium selenide solar cells, compound semiconductor solar cells, dye sensitized solar cells, multi-crystalline solar cells, thin film solar cells, compound semiconductor solar cells and amorphous silicon solar cells.    ADVANTAGE - The polymeric films or sheets suitable as solar cell encapsulant layers, is transparent, highly adhesive to other laminate layers, and moisture and heat resistant. The solar cell pre-lamination assembly uses terionomer multilayer film or sheet in cell modules which possess enhanced transparency, 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 high melting point polymer in the multilayer film or sheet may further provide improved thermal resistance. The terionomer multilayer films and sheets do not undergo any adhesion enhancing treatment and self-adhered to the other laminate layers.    DETAILED DESCRIPTION - A solar cell pre-lamination assembly comprises: a terionomer multilayer film or sheet and a solar cell component formed of several of electronically interconnected solar cells. 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, second surface sub-layer and optionally at least one inner sub-layer 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 which is 5-90% neutralized with at least one metal ion, based on the total carboxylic acid content of the acid terpolymer, and comprises repeat units derived from an alpha -olefin, alpha , beta -ethylenically unsaturated carboxylic acid having 3-8C (5-15 wt.%), and alpha , beta -ethylenically unsaturated carboxylic acid ester having 4-12C (15-40 wt.%). The high melting point polymer has a melting point of at least 80 degrees C. An INDEPENDENT CLAIM is included for formation (M1) of a solar cell module involving: providing a solar cell pre-lamination assembly and laminating the assembly to form a solar cell module.
