Multi-layer laminate structure and manufacturing method
The present invention is premised upon a multi-layer laminate structure and method of manufacture, more particularly to a method of constructing the multi-layer laminate structure utilizing a laminate frame and at least one energy activated flowable polymer.
1. A multi-layer laminate structure comprising:
at least four adjoining layers, the layers comprising:
an environmental shield layer including a top surface portion, a bottom surface portion, and a side surface portion connecting the top and the bottom surface portions and forming a periphery about the environmental shield layer, wherein the environmental shield layer functions as an environmental shield for successive layers;
a photovoltaic cell layer including a top surface portion, a bottom surface portion, and a side surface portion connecting the top and the bottom portions and forming a periphery about the photovoltaic cell, wherein the photovoltaic cell comprises one or more photovoltaic cells;
an energy activated flowable polymer layer including a top surface portion, a bottom surface portion and a side surface portion connecting the top and the bottom surface portions; and
an environmental protection layer including a top surface portion, a bottom surface portion, and a side surface portion connecting the top and the bottom surface portions;
wherein the energy activated flowable polymer layer at least is partially bonded to a portion of the side surface portion of the environmental shield layer and the photovoltaic cell layer creating a bead of energy activated flowable polymer about at least the periphery of the environmental shield layer and the photovoltaic cell layer, further wherein the bead has an untrimmed outer surface, and
wherein the energy activated flowable polymer is between the bottom surface portion of the photovoltaic cell layer and the top surface portion of the environmental protection layer or is between the bottom surface portion of the environmental shield layer and the top surface portion of the photovoltaic cell layer.
2. The multi-layer laminate structure according to claim 1 , wherein the environmental shield layer comprises a glass plate.
3. The multi-layer laminate structure according to claim 1 , wherein the environmental protection layer comprises a back sheet.
4. The multi-layer laminate structure according to claim 3 , wherein at least a portion of the back sheet includes a second energy activated flowable polymer.
5. The multi-layer laminate structure according to claim 1 , wherein the photovoltaic cell assembly comprises at least a cell portion and the cell portion is at least 5 mm from an exterior edge of the multi-layer laminate structure.
6. The multi-layer laminate structure according to claim 1 , wherein the structure includes five or more layers.
7. The multi-layer laminate according to claim 6 wherein the fifth layer is a bonding layer disposed between the bottom surface portion of the photovoltaic cell layer and the top surface portion of the environmental protection layer or is between the bottom surface portion of the environmental shield layer and the top surface portion of the photovoltaic cell layer.
8. The multi-layer laminate according to claim 6 wherein the structure includes a sixth layer comprising a supplemental barrier layer.
9. The multi-layer laminate according to claim 1 wherein the layer that functions as an environmental shield layer is constructed of transparent or translucent material that allows light energy to pass through to at least one underlying layer.
