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.
Claims8
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.
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.
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.
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.
