Abstract

The present disclosure provides a protective glass for a solar cell module having improved power generation efficiency of a solar cell obtained by minimizing reflection of light incident onto the protective glass, and a manufacturing method for the same. The protective glass for a solar cell module includes a plurality of glass beads formed in a spherical or hemispherical shape and arranged in the horizontal direction. The plurality of glass beads is disposed on at least one of the upper and lower portions of the sealing member.
In addition, the method of manufacturing a protective glass for a solar cell module includes preparing a plurality of glass beads formed in a spherical or hemispherical shape, arranging the glass beads in a horizontal direction, and injecting a molten glass solution into the glass beads and forming the protective glass.

First claim

What is claimed is:

1 . A protective glass for a solar cell module disposed on a sealing member for sealing a solar cell installed in a frame to protect the solar cell, the protective glass comprising:
a plurality of glass beads formed in a spherical or hemispherical shape and arranged in a horizontal direction, wherein the plurality of glass beads is disposed on at least one of an upper portion and a lower portion of the sealing member.

2 . The protective glass according to claim 1 , wherein the glass beads disposed on at least one of the upper portion and the lower portion of the sealing member are processed by heat treatment and attached to the sealing member.

3 . The protective glass according to claim 1 , wherein the glass beads are formed of tempered low-iron glass.

4 . The protective glass according to claim 1 , wherein the glass beads are processed through anti-reflection coating.

5 . The protective glass according to claim 1 , wherein a diameter of the glass beads is 3.2 mm to 8.0 mm.

6 . A protective glass for a solar cell module disposed on a sealing member for sealing a solar cell installed in a frame to protect the solar cell, the protective glass comprising:
a plurality of glass beads formed in a spherical or hemispherical shape and arranged in a horizontal direction; and a glass substrate attached to at least one of an upper portion and a lower portion of the sealing member, wherein the plurality of glass beads is disposed on at least one of the upper portion and the lower portion of the sealing member, wherein the glass beads are disposed on one surface of the glass substrate.

7 . The protective glass according to claim 6 , wherein the glass beads disposed on at least one of the upper portion and the lower portion of the sealing member are processed by heat treatment and attached to the sealing member.

8 . The protective glass according to claim 6 , wherein the glass beads are formed of tempered low-iron glass.

9 . The protective glass according to claim 6 , wherein the glass beads are processed through anti-reflection coating.

10 . The protective glass according to claim 6 , wherein a diameter of the glass beads is 3.2 mm to 8.0 mm.

11 . A method of manufacturing a protective glass for a solar cell module disposed on at least one of an upper portion and a lower portion of a sealing member for sealing the solar cell installed in a frame to protect the solar cell, the method comprising:
preparing a plurality of glass beads formed in a spherical or hemispherical shape; arranging the glass beads in a horizontal direction; and injecting a molten glass solution into the glass beads and forming the protective glass.

12 . The method according to claim 11 , wherein the injecting and forming comprises:
injecting the glass solution to a height less than half a height of the glass beads.
