METHOD FOR MANUFACTURING GRAPHIC COVER SUBSTRATE FOR SOLAR PANEL, SOLAR PANEL AND MANUFACTURING METHOD THEREFOR
A method for manufacturing a graphic cover substrate for a solar cell panel according to an embodiment of the present disclosure includes applying a cover layer, which is forming the cover layer composed of a ceramic material layer on a transfer member; transferring, which is transferring the cover layer to a base member; and reinforcing, which is forming a cover portion by reinforcing or semi-reinforcing the base member on which the cover layer is formed.
1 . A method for manufacturing a graphic cover substrate for a solar cell panel, comprising:
applying a cover layer, which is forming the cover layer composed of a ceramic material layer on a transfer member;
transferring, which is transferring the cover layer to a base member; and
reinforcing, which is forming a cover portion by reinforcing or semi-reinforcing the base member on which the cover layer is formed.
2 . The method of claim 1 , wherein the cover portion is composed of a ceramic oxide composition including a ceramic frit.
3 . The method of claim 2 , wherein the base member includes a glass substrate, and
the cover portion is composed of an integral part constituting a part of the glass substrate.
4 . The method of claim 1 , wherein in the applying the cover layer, the cover layer is formed by a printing process.
5 . The method of claim 4 , wherein in the applying the cover layer, the cover layer is formed by a digital inkjet printing process.
6 . The method of claim 5 , wherein the ceramic material layer includes a particle having a central particle diameter of 50 μm or more.
7 . The method of claim 1 , wherein a thickness of the cover portion is 20 um or less.
8 . The method of claim 1 , further comprising:
forming, which is forming the base member between the transferring and the reinforcing.
9 . The method of claim 1 , wherein one surface of the base member on which the cover portion is formed has a curved, uneven, or protruding portion having a height difference of 5 μm or more.
10 . A method for manufacturing a solar cell panel, comprising:
stacking, which is forming a stacked structure by stacking a first cover member, a first sealing material, a solar cell portion, a first sealing material, and a second cover member; and
laminating, which is integrating by applying heat and pressure to the stacked structure,
wherein the first cover member is formed by applying a cover layer, which is forming the cover layer composed of a ceramic material layer on a transfer member; transferring, which is transferring the cover layer to a base member; and reinforcing, which is forming a cover portion by reinforcing or semi-reinforcing the base member on which the cover layer is formed.
11 . The method of claim 10 , wherein the cover portion is composed of a ceramic oxide composition including a ceramic frit.
12 . The method of claim 11 , wherein the base member includes a glass substrate, and
the cover portion is composed of an integral part constituting a part of the glass substrate.
13 . The method of claim 10 , wherein in the applying the cover layer, the cover layer is formed by a printing process.
14 . The method of claim 13 , wherein in the applying the cover layer, the cover layer is formed by a digital inkjet printing process.
15 . The method of claim 10 , wherein a thickness of the cover portion is 20 um or less.
16 . The method of claim 10 , further comprising:
forming, which is forming the base member between the transferring and the reinforcing.
17 . The method of claim 10 , wherein one surface of the base member on which the cover portion is formed has a curved, uneven, or protruding portion having a height difference of 5 μm or more.
18 . A solar cell panel, comprising:
a solar cell;
a sealing material sealing the solar cell;
a first cover member positioned on one surface of the solar cell on the sealing material; and
a second cover member positioned on the other surface of the solar cell on the sealing material,
wherein the first cover member includes a base member having a curved, uneven, or protruding portion on one surface, and a cover portion formed on the one surface of the base member and made of an oxide ceramic composition.
19 . The solar cell panel of claim 18 , wherein a difference in height due to the curved, uneven, or protruding portion is 5 μm or more.
20 . The solar cell panel of claim 18 , wherein in the cover portion, a first transmittance, which is an average light transmittance of the cover portion with respect to light in an infrared region is equal to or greater than a second transmittance, which is an average light transmittance of the cover portion with respect to light in a visible light region.
