Abstract

A solar cell panel can include a solar cell; a sealing member for sealing the solar cell; a first cover member disposed on the sealing member at one side of the solar cell; and a second cover member disposed on the sealing member at another side of the solar cell, in which the first cover member includes a base member and a colored portion having a light transmittance lower than a light transmittance of the base member, the first cover member constituting a colored area, and the colored portion includes at least two layers each formed of an oxide ceramic composition and having different colors or different light transmittances.

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 disposed on the sealing member at a front side of the solar cell; and
a second cover member disposed on the sealing member at a back side of the solar cell,
wherein the first cover member includes a base member formed of glass and a colored portion having a light transmittance lower than a light transmittance of the base member, the colored portion constituting a colored area,
wherein the colored portion includes at least two layers each formed of an oxide ceramic composition having a glass structure of an amorphous state and different light transmittances, and
wherein the colored portion is fused to the base member, thereby a portion of the colored portion is embedded in the base member.

2. The solar cell panel of claim 1 , wherein an average light transmittance of the colored portion with respect to light in an infrared region is greater than or equal to an average light transmittance of the colored portion with respect to light in a visible light region.

3. The solar cell panel of claim 1 , wherein the at least two layers included the colored portion include a first layer disposed on the base member, and a second layer disposed on the first layer,
wherein the first layer and the second layer each include voids, and
wherein a size of the voids included in the first layer is smaller than a size of the voids included in the second layer or a total volume of the voids included in the first layer is less than a total volume of the voids included in the second layer.

4. The solar cell panel of claim 1 , wherein the colored portion includes a background layer and a colored layer stacked on each other or formed adjacent to each other.

5. The solar cell panel of claim 4 , wherein the background layer has a brightness or a light transmittance greater than a brightness or a light transmittance of the colored layer, or
wherein the background layer has a white-based color or a yellow-based color, or is transparent or translucent.

6. The solar cell panel of claim 4 , wherein the solar cell includes a plurality of solar cells, and
wherein at least a part of the background layer or at least a part of the colored layer is disposed at an inactive area where the plurality of solar cells are not located.

7. The solar cell panel of claim 4 , wherein the background layer is closer to the solar cell than the colored layer.

8. The solar cell panel of claim 1 , wherein the colored portion is formed at one surface of the first cover member and a light diffusion portion is formed at another surface of the first cover member.

9. The solar cell panel of claim 1 , wherein the at least two layers included the colored portion include a first layer disposed on the base member, and a second layer disposed on the first layer, and
wherein the portion of the colored portion embedded in the base member is a portion of the first layer.

10. The solar cell panel of claim 9 , wherein the colored portion is formed at one surface of the first cover member and a light diffusion portion is formed at another surface of the first cover member.

11. The solar cell panel of claim 10 , wherein the first layer and the second layer each include voids, and
wherein a size of the voids included in the first layer is smaller than a size of the voids included in the second layer or a total volume of the voids included in the first layer is less than a total volume of the voids included in the second layer.

12. The solar cell panel of claim 10 , wherein the colored portion is formed at one surface of the first cover member and a light diffusion portion is formed at another surface of the first cover member.

13. The solar cell panel of claim 4 , wherein the portion of the colored portion embedded in the base member is a portion of the background layer.

14. The solar cell panel of claim 13 , wherein the background layer has a brightness or a light transmittance greater than a brightness or a light transmittance of the colored layer, or
wherein the background layer has a white-based color or a yellow-based color, or is transparent or translucent.

15. The solar cell panel of claim 13 , wherein the solar cell includes a plurality of solar cells, and
wherein at least a part of the background layer or at least a part of the colored layer is disposed at an inactive area where the plurality of solar cells are not located.

16. The solar cell panel of claim 13 , wherein the background layer is closer to the solar cell than the colored layer.

17. The solar cell panel of claim 13 , wherein the colored portion is formed at one surface of the first cover member and a light diffusion portion is formed at another surface of the first cover member.
