At the same time, the drawings referred to in the following text mainly represent the structural schematics related to the features of the present invention, and do not need to be completely drawn according to the actual size, which will be explained first.

Referring to FIG. 1A, a first embodiment of the present invention is a color solar module having a naked-view 3D pattern, including a solar cell 200 and a light-transmissive color layer 100 formed on the surface of the solar cell 200. The solar cell module 200 is a solar cell that has been packaged, and the surface layer thereof may be glass, polyethylene terephthalate PET plastic, epoxy resin EPOXY, or other light transmissive materials, and the like.

The light transmissive color map layer 100 includes a white ink layer 110, a first transparent grating layer 120, a first pattern layer 130, a second pattern layer 140, a transparent layer 150, and a bottom layer sequentially stacked. The second transparent grating layer 160.

In order to manufacture the color solar module with the naked-view 3D pattern described in the first embodiment, the second embodiment of the present invention further provides a method for manufacturing a color solar module with a naked-view 3D pattern, as shown in FIG. 2A. , including the following steps:

S11: providing a solar cell 200;

S12: inkjet printing to form a white ink layer 110 on the surface of the solar cell 200, the white ink layer 110 comprises a grid of regularly arranged white dot density and white light transmission gap 112;

S13: forming a first transparent grating layer 120 on the white ink layer 110 by inkjet printing, the first transparent grating layer 120 is formed by a regularly arranged first transparent grating 121 having a first grating density;

S14: forming a first pattern layer 130 on the first transparent grating layer 120 by inkjet printing, the first pattern layer 130 comprising a first one of a plurality of first colored ink dots 131 of a plurality of colors. a first pattern having a grid-like first dot density and a first light-transmissive gap 132;

S15: forming a second pattern layer 140 on the first pattern layer 130 by inkjet printing, the second pattern layer 140 comprising a plurality of second colored ink dots 141 arranged in a plurality of colors. a second pattern 144 having a second dot density arranged in a grid and a second light transmission gap 142, the second dot density being higher than the first dot density and the first grating density;

S16: forming a transparent encapsulation layer 150 having a thickness of at least 2 mm on the second pattern layer 140 by using a transparent polymer material;

S17: forming a second transparent grating layer 160 on the transparent encapsulation layer 150 by inkjet printing. The second transparent grating layer 160 is formed by a regularly arranged second transparent grating 161 having a second grating density. The position of the second transparent grating layer 160 relative to the second pattern 144 has a hollowed out region 162.

Referring to FIG. 3, the white ink layer 110 is composed of white ink dots 111 arranged in a grid pattern, thereby forming a density of white ink dots 111, and white light-transmissive gaps 112 are formed between the white ink dots 111.

Referring to FIG. 5, the first pattern layer 130 is formed by regularly arranging a plurality of first colored ink dots 131 of a plurality of colors to form a first pattern. The first colored ink dot 131 in the first pattern has a grid-shaped first dot density, and a first light-transmitting gap 132 is formed between the first colored ink dots 131. The second pattern layer 140 is formed by regularly arranging a plurality of second colored ink dots 141 of a plurality of colors to form a second pattern 144. The second colored ink dots 141 in the second pattern 144 are regularly arranged in a grid shape to form a second dot density, and the second colored dots 141 have a second light-transmitting gap 142 therebetween.

Referring to FIG. 6, the first pattern layer 130 is mainly used as the substrate of the second pattern 144. The first dot density is low, the hue and saturation are also light, and the first light-transmissive gap 132 is wider. The second pattern 144 generally does not cover the entire first pattern layer 130, and functions to highlight the 3D stereo effect, the second dot density is higher, the hue and saturation are also thicker, and the second light transmission gap 142 is higher. A light transmissive gap 132 is narrow. Thereby, in a distant view, the second pattern 144 can float above the first pattern.

The first transparent grating layer 120, the transparent layer 150 and the second transparent grating layer 160 are intended to function as a human visual difference barrier in the present invention, thereby further highlighting the second pattern protruding floating on the first pattern layer 130. The resulting naked-eye 3D effect.

Referring to FIG. 4, the first transparent grating layer 120 is composed of a regularly arranged first transparent grating 121 to form a first grating density. Referring to FIG. 7, the second transparent grating layer 160 is composed of a regularly arranged second transparent grating 161, thereby forming a second grating density. Preferably, considering the optical effect, the first transparent grid 121 and the second transparent grid 161 may be a cylinder or a cone, and the cylinder is relatively simple to manufacture.

The diameter of the first transparent grating 121 of the first grating layer 120 is preferably 0.5 mm to 2 mm, the distance between the first transparent gratings 121 is preferably 1 mm to 2 mm, and the height between the first transparent gratings 121 is preferably 0.1 mm. ～1 mm, the first transparent grid 121 is a cylinder or a cone. The diameter of the second transparent grating 161 of the second grating layer 160 is preferably 0.5 mm to 2 mm, the distance between the second transparent gratings 161 is preferably 1 mm to 2 mm, and the height between the second transparent gratings 161 is preferably 0.1 mm. ~1mm.

For ease of manufacture, the transparent grating size and the transparent grid pitch in the first grating layer 120 and the second grating layer 160 may all use the same parameters, but it is better to adjust within the above range by highlighting the naked-view 3D effect. . It is particularly important that the first transparent grating 121 in the first grating layer 120 is regularly and evenly distributed throughout the layer, but the second grating layer 160 is provided with a hollowed out region 162 at a position relative to the second pattern 144. The second transparent grid 161 is not disposed in the region 162, and the second transparent grid 161 is evenly distributed outside the hollow region 162. Thereby, the naked-eye 3D effect of the second pattern 144 is more prominent.

In addition, in order to protect the first pattern layer 130 and the second pattern layer 140, and enhance the optical effect, in the light-transmitting color layer 100, the transparent layer 150 has a thickest thickness of at least 2 mm.

Referring to FIG. 3, the white ink layer 110 plays a key role in the present invention as a substrate for a color pattern, because the surface of the generally packaged solar cell module is dark blue or black, and it is not easy to form a bright saturation on the surface thereof. Colorful pattern. If a color pattern is formed directly on the surface of a dark blue or black solar cell module, not only the ink is consumed, but also the visual effect of the color pattern is poor. The invention uses the white ink layer 110 as a substrate, on the one hand, changes the surface color of the solar cell module, and on the other hand, can be used as a reflecting surface of sunlight, thereby making the color pattern seen by the human eye more vivid.

However, the white ink layer 110 also blocks sunlight from entering the solar cell module 200. Therefore, the white ink layer 110 is substantially a grid-like pattern formed by regularly arranging a plurality of white ink dots 111, and the white ink dots 111. A first white light-transmissive gap 112 is formed between the light for penetration, as shown in FIG.

The white light-transmissive gap 112 is very important in the present invention. If there is no white light-transmissive gap 112 in the white ink layer 110, the light will be blocked by a large amount, and the white ink layer 110 cannot be effectively penetrated to reach the bottom solar cell module. 200, this will seriously affect the luminous efficiency. The width of the white light transmission gap 112 must be appropriately set. Considering that the wavelength of the light generated by the solar cell module 200 is mainly visible light, the wavelength is 380 nm to 760 nm, so the white light transmission gap 112 is sufficient for visible light to pass through. The solar cell module 200 can be used to generate electricity. Preferably, the width of the white light transmitting gap 112 is from 0.002 mm to 0.015 mm, more preferably from 0.004 mm to 0.014 mm, by a plurality of experiments and tests. If it is too wide, although the light transmission effect is good, the effect as a pattern substrate is poor. If it is too narrow, the effect as a pattern substrate is good, but the light transmission effect is poor.

The line width of the white ink dots 111 between the respective white light-transmissive gaps 112 is also an important parameter, the line width is too wide, the effect as a pattern substrate is good, but the light transmission effect is poor; the line width is too narrow, and the light transmission effect is good. However, the effect as a pattern substrate is poor. In the present invention, preferably, the line width of the white ink dots 111 is substantially equal to the width of the white light transmission gap 112.

Considering the light transmission, 3D and the combined effect as a pattern substrate, preferably, the white dot density is higher than the first grating density in the first transparent grating layer 120, and the thickness of the white ink layer 110 is preferably 0.01 mm to 0.015. Mm.

As shown in FIG. 5, the second light-transmissive gap 142 in the second pattern layer 140 mainly functions to allow light to pass through, so that the solar cell module 200 can perform its intended function. Preferably, the ink used in the second pattern layer 140 comprises a cyan ink, a red ink, a yellow ink, and a black ink, whereby the ink jet printing forms a grid-like multicolor pattern.

The width of the second light-transmissive gap 142 must also be appropriately set. If it is too wide, although the light-transmitting effect is good, the effect as a color pattern is poor. If it is too narrow, the effect as a color pattern is good, but the light transmission effect is poor. In view of the width of the white light-transmissive gap 112 of the white ink layer 110, the width of the second light-transmissive gap 142 is preferably from 0.002 mm to 0.015 mm, more preferably from 0.004 mm to 0.014 mm, by many experiments and tests. The line width of the second colored ink dot 141 between each of the second light-transmissive gaps 142 is also an important parameter, and the line width is too wide, and the effect as a color pattern is good, but the light-transmitting effect is poor; the line width is too narrow, and the light transmission is too narrow. The effect is good, but the effect as a color pattern is poor. In the present invention, preferably, the line width of the second colored ink dot 141 is substantially equal to the width of the second light-transmitting gap 142.

Since the first pattern layer 130 and the second pattern layer 140 are formed on the first transparent grating layer 120, the second light transmission gap 142 is narrower than the first light transmission gap 132, and the second ink dot density is lower than the first ink dot density. And the first grating density is high, so the first colored ink dot 131 does not fill in the gap of the first transparent grating 121 of the first transparent grating layer 120, but the second colored ink dot in the second pattern 144 141 will be densely distributed evenly in the gap of the first transparent grid 121.

In the present invention, the white ink layer 110, the first transparent grating layer 120, the first pattern layer 130, the second pattern layer 140, and the second transparent grating layer 160 are all digitally controlled by inks of different colors (including transparent and colorless). The ink jet printing is preferably formed so that the dot size, dot density, gap width, layer height, and the like can be precisely controlled. In addition, the transparent layer 150 may be inkjet printed using a transparent ink, or may be directly pressed onto the second pattern layer 140 by using polyethylene terephthalate PET plastic, epoxy resin EPOXY, glass, or the like. There are no limits.

To control the dot size and line width, two parameters can be operated: one, adjusting the amount of white ink; and adjusting the illuminance of the UV lamp. When the amount of ink is constant, the irradiance of the radiance is increased, and the formed ink dots are small. Since the inkjet process produces an early curing phenomenon, the ink dots do not spatter when they fall on the surface of the object, and the formed ink dots are small. For example, when printing with a 720*720 dpi UV inkjet printer, 720*720 dpi means 518400 points in a square inch area, and the normal thickness of the ink layer is 0.01 mm because the ink is in the inkjet column. Splash loss occurs during the printing process, so the size of the generated ink dots is about 0.005 to 0.01 mm 2 , and the width of the light transmission gap is 0.002 to 0.007 mm, so that visible light having a wavelength of 380 to 760 nm can easily pass through. However, if higher solar energy efficiency is required, the amount of ink can be kept constant, and the irradiance can be increased to obtain a wider pitch, but the thickness of the ink is increased. Generally, the ink jet amount per unit time of the UV inkjet printer is fixed. When the inkjet thickness is increased from 0.01 mm to 0.015 mm, the width of the light transmission gap is increased by 50% to 0.004 to 0.014 mm, which allows more visible light. penetrate.

In this embodiment, preferably, the white ink layer 110 further comprises titanium dioxide particles 113, as shown in FIG. Titanium dioxide is an excellent photocatalyst that promotes the photoelectric conversion reaction. At the same time, the titanium dioxide particles 113 themselves appear white, mixed in the white ink layer 110, and do not change the color of the white ink; on the other hand, the titanium dioxide particles 113 themselves also have the effect of reflecting and scattering light, which can be shielded or absorbed by the ink. The light rays, which are reflected or scattered outward, pass through the white ink layer 110 to reach the underlying solar cell module 200, so that the luminous efficiency is less degraded.

Referring to FIG. 1B , based on the same technical concept, the present invention further provides a third embodiment, which is another color solar module with a naked-view 3D pattern, including a solar cell 200 and a surface formed on the surface of the solar cell 200.

The third embodiment can achieve an autostereoscopic 3D effect similar to that of the first embodiment, and wherein the third embodiment differs from the first embodiment in the relative position of the first transparent grating layer 120. In the third embodiment, the first transparent grating layer 120 is between the second pattern layer 140 and the strengthened glass 150A; in the first embodiment, the first transparent grating layer 120 is in the white ink layer 110 and the first pattern layer 130. between.
