Photovoltaic module with adhesion promoter

1. A photovoltaic module, comprising:

a solar cell comprising a first surface and a second surface, the second surface comprising a plurality of interspaced back-side contacts;

a first glass layer coupled to the first surface by a first encapsulating layer; and

a second glass layer coupled to the second surface by a second encapsulating layer, wherein the second encapsulating layer is not blended with an adhesion promoter, at least a portion of the second encapsulating layer bonded directly to the plurality of interspaced back-side contacts by an adhesion promoter comprising an aminosilane compound, wherein the second encapsulating layer is in contact with the adhesion promoter where the second encapsulating layer is bonded directly to the plurality of interspaced back-side contacts, but not where the second encapsulating layer is not bonded directly to the plurality of interspaced back-side contacts.

2. The photovoltaic module of claim 1 , wherein the adhesion promoter chemically bonds the second encapsulating layer to the plurality of interspaced back-side contacts.

3. The photovoltaic module of claim 1 , wherein the k-value of bond strength between the second encapsulating layer and the plurality of interspaced back-side contacts is greater than approximately 45 Newtons per centimeter.

4. The photovoltaic module of claim 1 , wherein the plurality of interspaced back-side contacts comprises a metal selected from the group consisting of aluminum, silver, copper and tin.

5. The photovoltaic module of claim 1 , wherein the first surface of the solar cell is free from contacts.
