Unless otherwise specifically indicated, the various raw materials, reagents, instruments, equipment and the like used in the present application are commercially available or may be prepared by existing methods.
The existing photovoltaic module has the technical problems that visible light irradiated on a photovoltaic cell panel and covered with a low-light-transmittance pigment part is less, and a hot spot effect is generated.
The technical scheme provided by the embodiment of the application aims to solve the technical problems, and the overall thought is as follows:
in a first aspect, the embodiment of the application provides a color photovoltaic module with obvious night color development, which comprises a photovoltaic cell panel and a color layer arranged on the photovoltaic cell panel,
the photovoltaic cell panel comprises a panel frame, a backboard, a photovoltaic cell and a transparent front plate, wherein the backboard, the photovoltaic cell and the transparent front plate are sequentially arranged in the panel frame in a laminated mode, adhesive films are arranged on two sides of the photovoltaic cell and are respectively adhered to the backboard and the transparent front plate through the adhesive films, and a junction box electrically connected with the photovoltaic cell is arranged on the backboard;
The color layer comprises a transparent light guide plate arranged on the transparent front plate and a pigment layer arranged on one surface of the transparent light guide plate far away from the photovoltaic cell panel, and the pigment layer comprises a dark color block and a light color block;
a plurality of grooves are formed in the surface, far away from the photovoltaic cell panel, of the transparent light guide plate, and the surface is opposite to the region of the dark color block;
the side of the transparent light guide plate is provided with a light source.
Those skilled in the art will appreciate that the panel frame is used to secure other panel-like members of the photovoltaic panel, including back sheets, photovoltaic cells, transparent front sheets. The material of the panel frame may be a conventional material in the art, such as a polymer material and a metal material.
Those skilled in the art will appreciate that the back sheet is a commercial product in the art. The back plate is mainly used for protecting the photovoltaic cell and providing support for the photovoltaic cell.
It will be appreciated by those skilled in the art that transparent front plates are commercially available in the art, and that transparent front plates commonly used in the art are made of ultra-white glass. Transparent polymers can also be selected as the material of the transparent front plate.
As will be appreciated by those skilled in the art, the junction box is used to output photocurrent generated by the photovoltaic cell.
As will be appreciated by those skilled in the art, the transparent light guide plate may be made of a material having high transparency, such as glass or organic glass.
It will be appreciated by those skilled in the art that the pigment layer is made of pigment, and the pigment may be a common pigment. As a preferred embodiment, the pigment is a UV curable ink. The UV light curing ink has the characteristics of strong adhesion, smooth surface, quick curing film formation, simple use and the like. The UV light curable ink may be printed on the transparent light guide plate by UV printing, screen printing, or the like.
As will be appreciated by those skilled in the art, since the photovoltaic panel itself is black or dark blue in color, the pigment layer generally includes a white pigment layer and a color pigment layer disposed on the white pigment layer, and in the present application, the dark color block is formed of a dark pigment in the color pigment layer, and the light color is formed of a light pigment in the color pigment layer.
Those skilled in the art will understand that the light source may be a conventional light source, and in practical application, an LED lamp is generally selected. The light source may be arranged outside the transparent light guide plate, for example, the LED lamp is tightly attached to the side of the transparent light guide plate, and an outer frame is further arranged to fix the LED lamp and the transparent light guide plate; the inside of the transparent light guide plate can be provided, for example, a groove is etched on the side edge of the transparent light guide plate by laser, and then the LED lamp is embedded into the groove.
Those skilled in the art will appreciate that there are a variety of well known ways to form the grooves in the plate member, and in the present application, as a preferred embodiment, the grooves are formed by laser etching.
Referring to fig. 3, during the night, light incident from the side of the transparent light guide plate is reflected between the grooves 3 for multiple times, so that the light distribution is more concentrated in the area where the dark color block is located, and the brightness of the dark color block is increased, thereby making the color development of the dark color block more obvious;
referring to fig. 4, during daytime, sunlight irradiates the photovoltaic panel obliquely in most cases, and when no grooves exist, the sunlight directly obliquely irradiates the transparent light guide plate, wherein a considerable part of the sunlight is reflected; when the grooves exist, sunlight can be reflected in the grooves for multiple times after entering the grooves obliquely, reflection and refraction can be simultaneously carried out on the walls of the grooves, and the refraction part is equivalent to successful incidence to the transparent light guide plate. Since sunlight is reflected in the grooves for multiple times, each reflection is accompanied by refraction, most sunlight can finally enter the transparent light guide plate in a refraction mode.
The above light path principle is only used as an illustration of a part of the principles of the present application, in practical situations, the groove wall and the groove bottom cannot be plane, and the light path is more complex, but is beneficial to increase the incidence of light as a whole.
According to the application, the plurality of grooves are formed in the transparent light guide plate relative to the areas of the dark color blocks, and light incident from the side parts of the transparent light guide plate can be reflected between the grooves for multiple times at night, so that the light distribution is more concentrated in the areas where the dark color blocks are positioned, and the brightness of the dark color blocks is increased, so that the color development of the dark color blocks is more obvious; during daytime, sunlight obliquely irradiates the photovoltaic cell panel under most conditions, and the sunlight obliquely enters the grooves and then is reflected in the grooves for multiple times, so that the sunlight is easier to enter the light guide plate and further enters the photovoltaic cell panel, the sunlight incidence quantity of the area where the dark color block is located is increased, and the hot spot effect is weakened.
In some embodiments of the application, the width of the groove is 0.01-0.05mm.
It can be understood by those skilled in the art that when the grooves are narrow, the pigment is not easy to penetrate into the grooves, and sunlight is directly reflected on the surface of the transparent light guide plate for multiple times after entering the grooves obliquely. If the pigment penetrates into the grooves, it covers the surfaces of the grooves and absorbs a large amount of sunlight, resulting in a reduction in sunlight incident from the grooves into the transparent light guide plate.
In some embodiments of the application, the depth of the grooves is 0.1-0.15mm.
As can be appreciated by those skilled in the art, when the depth of the groove is deepened, the light incident from the side of the transparent light guide plate is more significantly concentrated in the area where the dark color block is located, and the sunlight incident obliquely is subjected to more reflections, so that the sunlight incidence amount in the area where the dark color block is located is increased, that is, the beneficial effects described above tend to be enhanced as the depth of the groove is increased; however, after the depth of the groove is increased to a certain extent, the enhancement of the beneficial effect becomes no longer remarkable, and the processing difficulty becomes larger continuously along with the deepening of the depth of the groove, so that the value of the depth of the groove is more convenient.
In some embodiments of the present application, the grooves include first grooves arranged in parallel at equal intervals along a first direction and second grooves arranged in parallel at equal intervals along a second direction, the first direction and the second direction having a predetermined angle therebetween.
It will be appreciated by those skilled in the art that the equally spaced parallel arrangement between the first grooves and the equally spaced parallel arrangement between the second grooves allows the grooves to form a uniform grid.
In some embodiments of the application, the predetermined angle is 90 °.
In some embodiments of the application, the spacing between the first grooves is 0.1-0.3mm; and/or the number of the groups of groups,
The spacing between the second grooves is 0.1-0.3mm.
It can be understood by those skilled in the art that the smaller the distance between the grooves, the higher the concentration degree of the light incident on the side of the transparent light guide plate in the region where the dark color block is located and the more sunlight incident on the region where the dark color block is located, but on one hand, the too high brightness of the dark color block will affect the overall aesthetic degree, and on the other hand, the denser the grooves, the higher the processing cost will be, so that the distance between the grooves is more convenient to use the above values.
In some embodiments of the application, dots are provided at the edges of the light guide plate.
Those skilled in the art will appreciate that the dots are conventional structures of light guide plates, and the light emitted from the light source is concentrated, so that the concentrated light can be refracted at the dots more times by the dots to be more uniform.

Related experiment and effect data:
the hot spot effect was detected for the color photovoltaic modules of examples 1 to 5 and comparative examples, in which the temperatures of the center points of the dark color patch and the center point of the light color patch were detected by a temperature measuring gun, and the temperature difference between the temperature of the center point of the dark color patch and the temperature of the center point of the light color patch was calculated again by calculating the average value.
The test results are shown in the following table:
| Temperature difference (DEG C) | |
| Example 1 | 4.55 |
| Example 2 | 4.48 |
| Example 3 | 4.45 |
| Example 4 | 4.53 |
| Example 5 | 4.70 |
| Comparative example 1 | 5.0 |
| Comparative example 2 | 4.44 |
| Comparative example 3 | 4.73 |
The temperature difference in the table refers to the temperature difference between the temperature of the center point of the dark color patch and the temperature of the center point of the light color patch.
As can be seen from the above table, the temperature differences were all significantly reduced in examples 1-5 relative to comparative example 1.
In comparative examples 1-3, it was found that the temperature difference showed a decreasing trend with increasing trench depth.
Comparative examples 1 and 3, example 1 had a significantly lower temperature difference than comparative example 3, example 1 had a groove depth of 0.1mm, and comparative example 3 had a groove depth of 0.07mm, indicating that the shallow groove significantly resulted in an increase in temperature difference after the groove depth was less than 0.1 mm.
The temperature difference between comparative example 3 and comparative example 2 was about the same as that of example 3 and comparative example 2, but the trench depth of comparative example 2 was 0.17mm and the trench depth of example 3 was 0.15mm, which suggests that the effect on the temperature difference becomes very limited by continuing to deepen the trench depth after the trench depth exceeded 0.15 mm.
The white LED lamps of examples 1-5 and comparative examples 1-3 were turned on to emit light, and the dark color patches of examples 1-5 and comparative examples 2-3 were observed in dark, and the dark color patches of examples 1-5 and comparative examples 2-3 were found to be more visible as a whole, with the dark color patches and the light color patches being more coordinated in color and more similar to the daytime effect, while the dark color patches of comparative example 1 were not visibly distinguishable from the dark color patches of comparative example 1. This shows that the grooves on the light guide plate can significantly optimize the color development effect and visual effect of the color photovoltaic module at night.
