Abstract

An edge sealing tape for photovoltaic modules includes a primer suitable for bonding the edge sealing tape to the top sheet of the module. In one exemplary configuration, the edge sealing tape is a polyisobutylene-based material such as butyl and carries a primer disposed between one side of the edge sealing tape and a release liner wherein the primer is configured to bond with a fluoropolymer-based top sheet such that the edge sealing tape cohesively fails after the primer bonds the tape to the top sheet.

Claims (15)

1 . An edge sealing tape for photovoltaic modules comprising a sealing body and a primer disposed between a release layer and the sealing body; the primer suitable for bonding the edge sealing tape to a fluoropolymer-based top sheet.

2 . The edge sealing tape of claim 1 wherein the sealing body comprises a desiccated polyisobutylene-based material.

3 . A photovoltaic module comprising a top sheet and a bottom sheet sandwiching a semiconductor; an edge sealing tape disposed between the top and bottom sheets; the edge sealing tape including a desiccated sealing body and a primer disposed between the top sheet and the sealing body; the top sheet made from a fluoropolymer material.

4 . A method for forming the edge sealing tape for photovoltaic modules; the method including the steps of:

applying a primer adapted to bond to a fluoropolymer-based material onto a release layer to define a primer film assembly; the primer having a solvent;

flashing off the primer's solvent from the assembly;

slitting the primer film assembly to define a primed release layer;

extruding a desiccated sealing body material onto the primer of the primed release layer to define a desiccated edge sealing tape; and

winding the desiccated edge sealing tape for storage.

5 . The method of claim 4 , further comprising the step of winding the primed release layer for storage after the step of slitting the primer film.

6 . A method of forming a sealed photovoltaic module comprising the steps of:

sandwiching a photovoltaic semiconductor between a bottom substrate and a top sheet wherein the top sheet is formed from a fluoropolymer-based material;

sealing the edge of the bottom substrate to the edge of the top sheet with a desiccated sealing tape having a sealing body and a primer wherein the primer is adhered to the top sheet and the sealing body is adhered to the bottom substrate is such a way that the sealing body cohesively fails when the top sheet is pulled away from the bottom substrate.

7 . The method of claim 6 , wherein the sealing body is connected to the bottom substrate before the primer is connected to the sealing body.

8 . The method of claim 6 , wherein the sealing body is connected to the primer before the sealing body is connected to the bottom substrate.
