Abstract

A solar cell panel includes a solar cell; a sealing member for sealing the solar cell; a first cover member positioned at a first surface of the solar cell on a first side of the sealing member; and a second cover member positioned at a second surface of the solar cell on a second side of the sealing member. The first cover member includes a base member and a colored portion having a lower light transmittance than the base member and partially formed on the base member to form a colored region. The second cover member includes a cover portion having a lower brightness than the colored portion and positioned at least an inactive region where the solar cell is not positioned.

First claim

What is claimed is:

1. A solar cell panel comprising:
a solar cell;
a sealing member for sealing the solar cell;
a first cover member positioned at a first surface of the solar cell on a first side of the sealing member; and
a second cover member positioned at a second surface of the solar cell on a second side of the sealing member,
wherein the first cover member comprises a base member and a colored portion having a lower light transmittance than the base member and partially formed on the base member to form a colored region,
wherein the second cover member comprises a cover portion having a lower brightness than the colored portion of the first cover member and positioned at an inactive region of the solar cell panel where the solar cell is not positioned,
wherein the base member comprises a tempered glass substrate,
wherein the colored portion includes a ceramic frit and is formed of an integrated portion with the tempered glass substrate where at least a part of the ceramic frit and a material of the tempered glass substrate are mixed,
wherein the colored portion in the colored region has a plurality of portions and a light transmitting portion interposed between the plurality of portions, and
wherein the colored portion or the plurality of portions comprises an overlapped portion overlapped with the solar cell.

2. The solar cell panel of claim 1 , wherein the plurality of portions has at least one of a plurality of dots or a plurality of stripe shapes.

3. The solar cell panel of claim 1 , wherein the colored portion has a width of 0.2 to 10 mm, and
wherein a ratio of a total area of the colored portion to a total area of the colored region is in a range of 0.1 to 0.95.

4. The solar cell panel of claim 3 , wherein the ratio of the total area of the colored portion to the total area of the colored region is in a range of 0.1 to 0.5.

5. The solar cell panel of claim 1 ,
wherein the colored portion includes a pigment or a dyestuff.

6. The solar cell panel of claim 1 , wherein the colored portion is positioned at a surface of the tempered glass and partially formed at the tempered glass in a thickness direction of the base member at one surface of the base member.

7. The solar cell panel of claim 1 , wherein the colored portion has a first portion that is recessed into the base member and a second portion that protrudes from a substrate surface of the base member.

8. The solar cell panel of claim 7 , wherein a thickness of the first portion is greater than a thickness of the second portion.

9. The solar cell panel of claim 1 , wherein a first cover ratio is a ratio of an area of the colored portion to an area of the colored region,
wherein a second cover ratio is a ratio of an area of the cover portion positioned at the inactive region to an area of the inactive region, and
wherein the second cover ratio is greater than the first cover ratio.

10. The solar cell panel of claim 1 , wherein a color of the cover portion is at least one of an achromatic color other than white, an opaque color, or a same color as that of the solar cell.

11. The solar cell panel of claim 1 , wherein a color of the cover portion is at least one of black, gray, blue, green, brown, a same color as that of the solar cell, or a mixed color thereof.

12. The solar cell panel of claim 1 , wherein the cover portion has at least one of a dot shape, a stripe shape, or a shape covering at least an entire portion of the inactive region.

13. The solar cell panel of claim 1 , wherein the cover portion is formed at least one of entirely on the second cover member or partially at a portion including the inactive region.

14. A solar cell panel comprising:
a solar cell;
a sealing member for sealing the solar cell;
a first cover member positioned at a first surface of the solar cell on a first side of the sealing member; and
a second cover member positioned at a second surface of the solar cell on a second side of the sealing member,
wherein the first cover member comprises a base member and a colored portion having a lower light transmittance than the base member and partially formed on the base member to form a colored region,
wherein the second cover member comprises a cover portion positioned at an inactive region of the solar cell panel where the solar cell is not positioned,
wherein a first cover ratio is a ratio of an area of the colored portion to an area of the colored region, a second cover ratio is a ratio of an area of the cover portion positioned at the inactive region to an area of the inactive region, and the second cover ratio is greater than the first cover ratio,
wherein the base member comprises a tempered glass substrate,
wherein the colored portion includes a ceramic frit and is formed of an integrated portion with the tempered glass substrate where at least a part of the ceramic frit and a material of the tempered glass substrate are mixed,
wherein the colored portion in the colored region has a plurality of portions and a light transmitting portion interposed between the plurality of portions, and
wherein the colored portion or the plurality of portions comprises an overlapped portion overlapped with the solar cell.

15. The solar cell panel of claim 14 , wherein a color of the cover portion is at least one of an achromatic color other than white, an opaque color, or a same color as that of the solar cell.

16. The solar cell panel of claim 14 , wherein a color of the cover portion is at least one of black, gray, blue, green, brown, a same color as that of the solar cell, or a mixed color thereof.

17. The solar cell panel of claim 14 , wherein the second cover ratio is in a range of 0.5 to 1.

18. The solar cell panel of claim 14 , wherein the cover portion has at least one of a dot shape, a stripe shape, or a shape covering at least an entire portion of the inactive region.

19. The solar cell panel of claim 14 , wherein the cover portion is formed at least one of entirely on the second cover member or partially at a portion including the inactive region.

20. The solar cell panel of claim 14 , wherein the solar cell panel has a building integrated structure.
