Solar module with aligning encapsulant
View Patent ↗A photovoltaic module can include an encapsulant having an alignment portion configured to maintain alignment of solar cells during manufacture of the photovoltaic module.
1. A method for manufacturing a solar cell module, the method comprising:
placing a first surface of a first encapsulant having an alignment portion on a substantially transparent top cover, wherein the alignment portion of the first encapsulant comprises a plurality of recesses formed in a second surface of the first encapsulant, the second surface opposite the first surface, wherein each of the plurality of recesses has a polygon geometry having at least six sides, wherein the second surface of the encapsulant is textured only in the plurality of recess;
placing a plurality of solar cells in corresponding ones of the plurality of recesses of the alignment portion of the first encapsulant, wherein the plurality of solar cells remains exposed after placing the plurality of solar cells in the corresponding ones of the plurality of recesses of the alignment portion of the first encapsulant;
subsequent to placing the plurality of solar cells in corresponding ones of the plurality of recesses of the alignment portion of the first encapsulant, metallizing the plurality of solar cells on a side of the plurality of solar cells opposite the recesses, wherein the plurality of recesses of the alignment portion of the first encapsulant hold the plurality of solar cells in place during the metallizing the plurality of solar cells;
subsequent to metallizing the plurality of solar cells on the side of the plurality of solar cells opposite the recesses, placing a second encapsulant over the plurality of solar cells and on the second surface of the first encapsulant; and
bonding the first and second encapsulants to the plurality of solar cells.
2. The method of claim 1 , wherein bonding the first and second encapsulants comprises exposing the first and second encapsulants to ultraviolet (UV) light.
3. The method of claim 1 , wherein bonding the first and second encapsulants comprises heating the first and second encapsulants.
4. The method of claim 1 , further comprising placing a backsheet on the second encapsulant prior to bonding.
5. The method of claim 4 , wherein the bonding also bonds the backsheet to the second encapsulant.
6. The method of claim 5 , further comprising:
coupling a photovoltaic laminate on a frame, the photovoltaic laminate comprising the plurality of solar cells, the first and second encapsulants, the substantially transparent top cover, and the backsheet.
7. The method of claim 1 , further comprising forming the plurality of recesses in the second surface of the first encapsulant by embossing the first encapsulant.
8. The method of claim 1 , wherein bonding at least partially smooths the alignment portion of the first encapsulant.
9. The method of claim 1 , further comprising forming the alignment portion.
10. A method for manufacturing a solar cell module, the method comprising:
placing a first surface of a first encapsulant having an alignment portion on a substantially transparent top cover, wherein the alignment portion of the first encapsulant comprises a plurality of recesses formed in a second surface of the first encapsulant, the second surface opposite the first surface, wherein the second surface of the encapsulant is textured only in the plurality of recess;
placing a plurality of solar cells in corresponding ones of the plurality of recesses of the alignment portion of the first encapsulant, wherein the plurality of solar cells remains exposed after placing the plurality of solar cells in the corresponding ones of the plurality of recesses of the alignment portion of the first encapsulant;
subsequent to placing the plurality of solar cells in corresponding ones of the plurality of recesses of the alignment portion of the first encapsulant, metallizing the plurality of solar cells on a side of the plurality of solar cells opposite the recesses, wherein the plurality of recesses of the alignment portion of the first encapsulant hold the plurality of solar cells in place during the metallizing the plurality of solar cells;
subsequent to metallizing the plurality of solar cells on the side of the plurality of solar cells opposite the recesses, placing a second encapsulant over the plurality of solar cells and on the second surface of the first encapsulant; and
bonding the first and second encapsulants to the plurality of solar cells.
11. The method of claim 10 , wherein bonding the first and second encapsulants comprises exposing the first and second encapsulants to ultraviolet (UV) light.
12. The method of claim 10 , wherein bonding the first and second encapsulants comprises heating the first and second encapsulants.
13. The method of claim 10 , further comprising placing a backsheet on the second encapsulant prior to bonding.
14. The method of claim 13 , wherein the bonding also bonds the backsheet to the second encapsulant.
15. The method of claim 14 , further comprising:
coupling a photovoltaic laminate on a frame, the photovoltaic laminate comprising the plurality of solar cells, the first and second encapsulants, the substantially transparent top cover, and the backsheet.
16. The method of claim 10 , further comprising forming the plurality of recesses in the second surface of the first encapsulant by embossing the first encapsulant.
17. The method of claim 10 , wherein bonding at least partially smooths the alignment portion of the first encapsulant.
18. The method of claim 10 , further comprising forming the alignment portion.
