Abstract

A layer for use in a photovoltaic module may include an interlayer and one or more corrosion barriers adjacent to an electrically conductive layer.

Claims (26)

1 . A layer for use in a photovoltaic module comprising:

an interlayer; and

one or more corrosion barriers adjacent to the interlayer for preventing corrosion of an electrically conductive layer, when the interlayer is installed adjacent to the electrically conductive layer.

2 . The layer of claim 1 , wherein the corrosion of the electrically conductive layer is acid-induced.

3 . The layer of claim 2 , wherein an acid of the acid-induced corrosion is formed within the interlayer.

4 . The layer of claim 1 , wherein the interlayer comprises a material selected from a group consisting of ethylene vinyl acetate (EVA), polyvinyl butyral (PVB), and thermoplastic polyurethane (TPU).

5 . The layer of claim 1 , wherein the one or more corrosion barriers comprise a material selected from the group consisting of polyester and polyethylene terephthalate (PET).

6 . The layer of claim 1 , further comprising an adhesive layer between the interlayer and the one or more corrosion barriers.

7 . The layer of claim 6 , wherein the adhesive layer comprises an acrylic adhesive.

8 . The layer of claim 1 , wherein the one or more corrosion barriers are opaque.

9 . A method for manufacturing an interlayer for a photovoltaic module, the method comprising:

forming an interlayer; and

forming one or more corrosion barriers adjacent to the interlayer using an adhesive.

10 . The method of claim 9 , further comprising wrapping the interlayer around a cylindrical core to facilitate transport and dispensing.

11 . The method of claim 9 , further comprising forming an opening in the interlayer, wherein the opening is configured to align with an opening in a back cover of a module upon assembly.

12 . The method of claim 9 , wherein the interlayer comprises a material selected from the group consisting of ethylene vinyl acetate (EVA), polyvinyl butyral (PVB), and thermoplastic polyurethane (TPU).

13 . A photovoltaic device comprising:

an interlayer; and

at least one corrosion barrier adjacent to an electrically conductive layer for preventing the electrically conductive layer from corroding.

14 . The photovoltaic device of claim 13 , wherein the electrically conductive layer comprises a conductive tape.

15 . The photovoltaic device of claim 14 , wherein the at least one corrosion barrier is aligned with and wider than the conductive tape.

16 . The photovoltaic device of claim 13 , wherein the interlayer comprises a material selected from the group consisting of ethylene vinyl acetate (EVA), polyvinyl butyral (PVB), and thermoplastic polyurethane (TPU).

17 . The photovoltaic device of claim 13 , wherein the at least one corrosion barrier comprises a material selected from the group consisting of polyester and polyethylene terephthalate (PET).

18 . The photovoltaic device of claim 14 , wherein the conductive tape comprises tin-plated copper.

19 . The photovoltaic device of claim 13 , wherein the at least one corrosion barrier is opaque.

20 . The photovoltaic device of claim 13 , wherein the at least one corrosion barrier is attached to the interlayer by an adhesive layer.
