An improved backsheet used in the construction of solar panels is disclosed. A method of manufacturing the backsheet and solar panel comprising the backsheet, including coextrusion processes are also disclosed. Additionally, a photovoltaic solar panel module comprising the backsheet of the invention is disclosed. The backsheet of the instant invention may comprise an exterior layer having inner and outer surfaces, a middle layer, having inner and outer surfaces, and an interior layer having inner and outer surfaces. In one embodiment of the invention, the outer surface of the middle layer may be adjoined to the inner surface of the exterior layer, and the inner surface of the middle layer may be adjoined to the outer surface of the interior layer. The exterior layer, middle layer, and interior layer may be adjoined via a co-extrusion process, thereby eliminating the need for the use of adhesives for bonding the layers of the backsheet together. The backsheet of the invention improves upon the efficiency, strength, weather resistance, cost, and useful life of the solar panels in which the backsheet is incorporated.

Coextruded solar panel backsheet and method of manufacture

Laminates of having a first outer layer of weatherable film, at least one mid layer, and a second outer layer containing an opacifying quantity of white pigment. The laminates are particularly useful for protecting photovoltaic cells, solar panels, and circuit boards. In photovoltaic cells, the laminates result in increased power generation.

Bright white protective laminates

Laminates of having a first outer layer of polyvinyl fluoride, at least one mid layer, and a second outer layer of polyvinyl fluoride, ethylene vinyl acetate or polyolefin with a surface of ionomer. The laminates are particularly useful for protecting photovoltaic cells, solar panels, and circuit boards.

Barrier laminate

Laminates of polyvinylidene fluoride films and sheets of resins thermoformable at temperatures greater than about 500&deg; F. (260&deg; C.), three dimensional structures formed therefrom and processes for their manufacture and use are disclosed.

Polyvinylidene fluoride coated articles from resins formable at high temperatures

Laminar structures of PVF and substantially amorphous resin such as PEKK, backfilled with injection molding resin, exhibit an excellent combination of physical and aesthetic properties.

Molded PVF laminar structures

Thin laminates of polyarylether ketone ketone and polyvinyl fluoride can be embossed without destruction of the polyvinyl fluoride and, on combustion, result in low smoke levels.

Embossable laminates

A process for preparing laminates of polyvinyl fluoride and at least one other fluoropolymer that are free from adhesive at the interface by dispersion coating a first film to form a second film and curing the second film at a temperature below the melting point of the first film.

Method of making fluoropolymer laminates

Laminates of polyvinyl fluoride and at least one other fluoropolymer that are free from adhesive at the interface and a process for preparing the laminates by dispersion coating a first film to form a second film and curing the second film at a temperature below the melting point of the first film.
