Abstract

A solar cell assembly and a method of bonding a solar cell component to a flexible support are disclosed. The solar cell assembly comprises a flexible support with a predetermined size, a solar cell component, bonding adhesive between the support and the solar cell component, wherein the support with the predetermined size has substantially uniform borders of 0.003 inches to 0.2 inches in width extending beyond the edges of the solar cell component.

First claim

The invention claimed is:

1. A method of bonding a solar cell component to a support, the method comprising:
providing a solar cell component having a top side and a bottom side;
providing a flexible support having a top side and a bottom side;
cutting the support to a predetermined size;
dispensing bonding adhesive on the top side of the support or on the bottom side of the solar cell component; and
contacting the bottom side of the solar cell component with the top side of the support,
wherein each border of the support independently extends beyond a corresponding edge of the solar cell component by a width of 0.003 inches to 0.2 inches.

2. The method of claim 1 , wherein the bonding adhesive comprises rigid particles of substantially uniform size.

3. The method of claim 2 , wherein the rigid particles are glass and spherical or substantially spherical.

4. The method of claim 1 , wherein the bonding adhesive has a viscosity of 1000 mPas to 50000 mPas.

5. The method of claim 1 , wherein contacting further comprises weighting the solar cell component in contact with the support.

6. The method of claim 1 , wherein the solar cell component comprises multiple mechanical standoffs that are interconnects or shims on the bottom side of the solar cell component.

7. The method of claim 1 , wherein the solar cell component is selected from the group consisting of a solar cell, a coverglass-interconnect-cell (CIC) assembly, a string of solar cells, a string of a coverglass-interconnect-cells (CICs), and combinations thereof.

8. The method of claim 1 , wherein each border of the support independently extends beyond a corresponding edge of the solar cell component by a width of 0.003 inches to 0.1 inches.

9. The method of claim 1 , wherein each border of the support independently extends beyond a corresponding edge of the solar cell component by a width of 0.003 inches to 0.05 inches.

10. The method of claim 1 , wherein each border of the support independently extends beyond a corresponding edge of the solar cell component by a width of 0.005 inches to 0.025 inches.

11. The method of claim 1 , wherein each border of the support independently extends beyond a corresponding edge of the solar cell component by a width of 0.010 inches to 0.025 inches.

12. The method of claim 1 wherein each border of the support extends beyond a corresponding edge of the solar cell component by a substantially uniform width of 0.003 inches to 0.2 inches.

13. A method of bonding a solar cell component to a support, the method comprising:
providing a non-flat, bowed solar cell component having a top side and a bottom side;
providing a flexible support having a top side and a bottom side;
cutting the support to a predetermined size;
dispensing bonding adhesive on the top side of the support or on the bottom side of the solar cell component; and
contacting the bottom side of the solar cell component with the top side of the support,
wherein each border of the support independently extends beyond a corresponding edge of the solar cell component by a width of 0.003 inches to 0.2 inches.

14. The method of claim 13 , wherein the bonding adhesive comprises rigid particles of substantially uniform size.

15. The method of claim 14 , wherein the rigid particles are glass and spherical or substantially spherical.

16. The method of claim 13 , wherein the bonding adhesive has a viscosity of 1000 mPas to 50000 mPas.

17. The method of claim 13 , wherein contacting further comprises weighting the solar cell component in contact with the support.

18. The method of claim 13 , wherein the solar cell component is selected from the group consisting of a solar cell, a coverglass-interconnect-cell (CIC) assembly, a string of solar cells, a string of a coverglass-interconnect-cells (CICs), and combinations thereof.

19. The method of claim 13 wherein each border of the support extends beyond a corresponding edge of the solar cell component by a substantially uniform width of 0.003 inches to 0.2 inches.

20. A method of bonding a solar cell component to a support, the method comprising:
providing a non-flat, bowed solar cell component having a top side and a bottom side, wherein the solar cell component comprises multiple mechanical standoffs that are interconnects or shims on the bottom side of the solar cell component, wherein the solar cell component is selected from the group consisting of a solar cell, a coverglass-interconnect-cell (CIC) assembly, a string of solar cells, a string of a coverglass-interconnect-cells (CICs), and combinations thereof;
providing a flexible support having a top side and a bottom side;
cutting the support to a predetermined size;
dispensing bonding adhesive having a viscosity of 1000 mPas to 50000 mPas on the top side of the support or on the bottom side of the solar cell component, wherein the bonding adhesive comprises rigid glass particles of substantially uniform size that are spherical or substantially spherical;
contacting the bottom side of the solar cell component with the top side of the support; and
weighting the solar cell component in contact with the support,
wherein each border of the support extends beyond a corresponding edge of the solar cell component by a substantially uniform width of 0.010 inches to 0.025 inches.
