The present invention mainly discloses the application of a solar cell, wherein the electrochemical basic principle of the solar power generation used is well known to those skilled in the relevant art, and therefore, the description below will not be fully described. At the same time, the drawings referred to in the following text mainly express the structural schematics related to the present creative features, and do not need to be completely drawn according to the actual size, which will be explained first.

Referring to FIG. 1, a first embodiment of the present invention is a color solar module 1 comprising a solar cell module 200 and a light transmissive color film 300 attached to a surface of the solar cell module 200.

The transparent color film 300 includes a light transmissive film body 310 and a light transmissive color layer 100. The light transmissive color layer 100 includes a white ink layer 110 and a multicolor ink layer 120. The white ink layer 110 is formed on the solar cell module. On the surface of 200, a multi-color ink layer 120 is formed on the surface of the white ink layer 110. 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 white ink layer 110 plays a key role in the creation of the substrate as a color pattern because the surface of the solar cell module which is generally packaged is dark blue or black, and it is not easy to form a vivid saturated color pattern on the surface thereof. 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 light transmissive color film 300 of the present 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, More saturated.

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 light-transmissive gap 112 is formed therebetween for light to pass through, as shown in FIG.

The first light-transmissive gap 112 is very important in the present creation. If there is no first 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. Therefore, the white ink layer 110 is preferably controlled by a digitally controlled ink jet printing mechanism having a UV hardening function, so that the width of the first light transmitting gap 112 can be precisely controlled.

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

The white ink layer 110 is preferably formed in a digitally controlled ink jet printing manner so that the line width of the white ink dots 111 and the width of the first light transmitting gap 112 can be precisely controlled.

To control the line width of the white ink dot 111, 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 white ink dot 111 on the surface of the solar cell module 200 is small, because the inkjet process produces an early curing phenomenon, and the white ink dot 111 does not fall on the surface of the solar cell module 200. A splash phenomenon occurs, and the formed white ink dots 111 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 white ink layer 110 is normally formed to a thickness of 0.01 mm because the ink is being sprayed. There is a splash loss in the ink printing process, so the size of the generated white ink dot 111 is about 0.005 to 0.01 square millimeter, and the width of the first light transmission gap 112 is 0.002 to 0.007 mm, so that the wavelength is 380 to 760 nm. Visible light passes easily. 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 white ink is increased. Generally, the ink ejection amount per unit time of the UV inkjet printer is fixed, and when the thickness of the inkjet is increased from 0.01 mm to 0.015 mm, the width of the first light transmission gap 112 is increased by 50% to 0.004 to 0.014 mm, which allows More visible light penetration.

In this embodiment, the color pattern is mainly composed of the multi-color ink layer 120. 2, the multi-color ink layer 120 includes a grid-like multi-color pattern formed by regularly arranging a plurality of colored ink dots 121 of a plurality of colors, and a second light-transmissive gap 122 is formed between the colored ink dots 121. For the light to penetrate, the second light-transmissive gap 122 mainly functions to allow light to penetrate, so that the solar cell module 200 can perform its intended function. Preferably, the ink used in the multi-color ink layer 120 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 122 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. Considering the width of the first light-transmissive gap 112 of the white ink layer 110, the width of the second light-transmissive gap 122 is preferably from 0.002 mm to 0.015 mm, more preferably from 0.004 mm to 0.014, through multiple experiments and tests. Millimeter. The line width of the colored ink dots 121 between the respective second light-transmissive gaps 122 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-transmitting effect is good. However, the effect as a color pattern is poor. In the present creation, preferably, the line width of the colored ink dot 121 is substantially equal to the width of the second light transmitting gap 122.

The multi-color ink layer 120 is preferably formed in a digitally controlled ink jet printing manner so that the width of the second light-transmissive gap 122 can be precisely controlled.

In consideration of the light transmission and the overall effect as a pattern substrate, in the present embodiment, the white ink layer 110 has a thickness of 0.01 mm to 0.015 mm.

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.

In this embodiment, the color solar module 1 further includes an adhesive layer 320 disposed between the solar cell module 200 and the transparent color film 300, as shown in FIG. The light color film 300 is firmly attached to the surface of the solar cell module 200.

According to the technical idea of the present invention, the light-transmissive color layer 100 can also be formed into a pattern having a three-dimensional effect to make the pattern more vivid. See FIG. 3, a second preferred embodiment of the present invention, a color solar module 10. The specific implementation manner is to adjust the thickness of the white ink layer 110. Referring to FIG. 3, the white ink layer 110 includes a first thickness 115 and a second thickness 116. The first thickness 115 is 0.01 mm to 0.015 mm, and the second thickness 116 is 116. A thickness 115 is thicker, and the position at which the second thickness is located is a position where a three-dimensional convex effect is preliminarily provided. The thicker the second thickness 116, the better the stereoscopic effect. Preferably, the present application suggests that the second thickness 116 be at least twice the first thickness 115. After the white ink layer 110 is cured, a multi-color ink layer 120 is then formed on the surface of the white ink layer 110. At this time, the multi-color ink layer 120 may have a single thickness, and the upper portion of the white ink layer 110 is passed through. The second thickness 116, that is, the position of the multi-color ink layer 120 can be raised to form a stereoscopic effect.

The stereoscopic effect is formed by different heights of the white ink layer 110, and the amount of colored ink used is smaller, the manufacturing cost is lower, and the effect on the light transmission effect is smaller than that of directly forming the multi-color ink layer 120 of different thicknesses. . Because the colored ink dot 121 shields more light than the white ink dot 111, the influence on the luminous efficiency is greatly affected.

Through the above description, the advantages of this creation are summarized as follows:

First, the light-transmissive color layer 100 is directly formed on the transparent film body 310, and then attached to the solar cell module 200, which is relatively simple to manufacture and easier to mass-produce.

2. The light-transmissive color layer 100 is composed of a multi-color ink layer 120 and a white ink layer 110 at the bottom thereof, which can eliminate the adverse effects of the dark blue or black surface of the solar cell module 200, and the color pattern is more saturated and vivid.

3. The multi-color ink layer 120 and the white ink layer 110 at the bottom thereof respectively have a suitable second light-transmissive gap 122 and a first light-transmissive gap 112, which can provide sufficient light-transmitting effect for the luminous efficiency of the solar cell module 200. The impact of impairment is small.

Fourth, the color solar module can have a saturated and vivid color pattern, and sufficient luminous efficiency to cope with actual use.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention; the above description should be understood and implemented by those skilled in the relevant art, so that other spirits are not disclosed in the present disclosure.
