Abstract

Disclosed are a solar cell module and a method of fabricating the same. The solar cell module includes a support substrate, solar cells at an upper portion of the support substrate, bus bars electrically connected to the solar cells, a junction box connected to the bus bars, and an upper substrate at an upper portion of the solar cells. The junction box is formed therein with pad electrodes connected to the bus bars.

First claim

The invention claimed is:

1. A solar cell module comprising:
a support substrate;
solar cells at an upper portion of the support substrate;
bus bars electrically connected to the solar cells;
a junction box connected to the bus bars; and
an upper substrate at an upper portion of the solar cells,
wherein the junction box is disposed therein with pad electrodes connected to the bus bars and comprises a lower junction box disposed on a top surface of the support substrate and an upper junction box disposed on a bottom surface of the upper substrate, and
wherein the pad electrodes are disposed on a top surface of the lower junction box and a bottom surface of the upper junction box and are connected to the bus bars, respectively.

2. The solar cell module of claim 1 , wherein the bus bars are disposed at both end portions of the solar cells, and the pad electrodes are connected to the bus bars, respectively.

3. The solar cell module of claim 1 , wherein the support substrate and the upper substrate have widths wider than widths of the solar cells.

4. The solar cell module of claim 1 , further comprising a protective layer disposed on the upper portion of the solar cells.

5. The solar cell module of claim 4 , wherein a thickness of the junction box less than a total thickness of the upper substrate, the protective layer and the support substrate.

6. The solar cell module of claim 1 , wherein the pad electrodes comprise a lower pad electrode on the top surface of the lower junction box and
an upper pad electrode at a position corresponding to a position of the lower pad electrode on the bottom surface of the upper junction box.

7. The solar cell module of claim 1 , wherein the lower and upper junction boxes are provided at lateral sides thereof with holes.

8. The solar cell module of claim 7 , wherein the holes are cable connection holes, and wherein the cable connection holes comprise semicircular shapes at the lower and upper junction boxes.

9. The solar cell module of claim 8 , wherein the cable connection holes are spaced apart from the support substrate and the upper substrate.

10. The solar cell module of claim 1 , wherein the junction box includes connection parts connected to the pad electrodes, and the connection parts are electrically connected to a cable.

11. The solar cell module of claim 10 , wherein the connection parts include a material the same as materials constituting the pad electrodes.

12. The solar cell module of claim 10 , wherein the connection parts have a substantially C-shape section.

13. The solar cell module of claim 1 , wherein the junction box is disposed at lateral sides of the upper substrate and the support substrate.

14. The solar cell module of claim 1 , wherein the junction box includes a by-pass diode.

15. The solar cell module of claim 1 , wherein the bus bars are disposed between the solar cells and the pad electrodes.

16. The solar cell module of claim 1 , wherein the pad electrodes are disposed in the support substrate and the upper substrate.

17. The solar cell module of claim 1 , wherein the connection parts are disposed in the junction box, and are disposed at inside and outer side of the support substrate.
