Technical Field

[0001] The invention relates to the technical field of solar cells, and in particular to a solar cell panel and a solar cell panel assembly. Background Art

[0002] As a clean and renewable energy, the use of solar energy has become a key way to promote energy structure transformation and achieve sustainable development worldwide. In this context, the research and development and application of solar panels, as the core equipment for capturing and converting solar energy, have received widespread attention.

[0003] Currently, most solar panels on the market adopt a standard structural design, which mainly includes cells, packaging materials, back panels and frames. The cells are responsible for absorbing sunlight and converting it into electrical energy. The packaging layer usually uses transparent materials, which not only protects the cells from environmental factors, but also can maximize the transmission of sunlight.

[0004] However, in actual applications, in order to meet certain aesthetic or functional requirements, solar panels are sometimes covered with specific patterns. Although these patterns can provide certain decorative or shielding effects, they often lead to a decrease in the light transmittance of the solar panel, which directly affects the light absorption efficiency of the solar panel, and further affects its overall photoelectric conversion performance. Summary of the invention

[0005] The main purpose of the present invention is to provide a solar panel and a solar panel assembly, which aims to ensure the functionality of the solar panel while also achieving diversified appearance effects to meet the needs of different scenarios and users.

[0031] The present invention provides a solar cell panel 100 .

[0032] See also Figures 1 to 3 In one embodiment of the present application, the solar cell panel 100 includes: a battery chip 1 and a light-transmitting color film 2, the light-transmitting color film 2 includes a first light-transmitting connecting layer 21 and a first light-transmitting pattern layer 22 which are stacked; the first light-transmitting connecting layer 21 is connected to the battery chip 1 on the side facing away from the first light-transmitting pattern layer 22.

[0033] The solar panel provided by the present invention can improve the light transmittance of the solar panel while maintaining the original decorative effect of the solar panel by setting a light-transmitting color film 2 on the solar panel. Compared with the traditional full-coverage pattern design, this improved solution can reduce the pattern's blocking of sunlight, thereby improving the photoelectric conversion performance of the solar panel, helping to reduce energy waste, further promote the popularization of clean and renewable energy, and achieve sustainable development. In addition, the design of the light-transmitting color film 2 not only meets aesthetic needs, but also ensures the functionality of the solar panel, and by adjusting the shape, color and distribution of the light-transmitting pattern layer, a variety of appearance effects can be achieved to meet the needs of different scenes and users.

[0034] It should be noted that, in one embodiment of the present application, the first light-transmitting connection layer 21 may be an EVE transparent adhesive film. The EVE (ethylene-vinyl acetate copolymer) transparent adhesive film has high transparency, which can ensure that most of the sunlight penetrates, thereby improving the photoelectric conversion efficiency of the solar panel. The EVE transparent adhesive film has good bonding and sealing properties, and can firmly connect the first light-transmitting pattern layer 22 and the battery chip 1 to ensure the stability of the entire light-transmitting color film 2. The EVE transparent adhesive film usually has good waterproof properties, which can prevent moisture from penetrating into the battery chip 1 and protect the internal circuit from moisture. In other embodiments, the first light-transmitting connection layer 21 may also be a PET adhesive film or a silicone film.

[0035] In one embodiment of the present application, the light-transmitting pattern layer includes a plurality of light-transmitting color blocks 221 arranged at intervals. The plurality of light-transmitting color blocks 221 arranged at intervals help to distribute light more evenly on the surface of the solar panel, reduce the shadow effect that may be caused by a single pattern covering, thereby improving the light absorption efficiency of the entire solar panel, and through different light-transmitting color blocks 221, a unique visual effect can be provided for the solar panel to form one or more pattern images together to meet personalized design needs without affecting its functionality. In addition, different light-transmitting color blocks 221 can also have different light transmittances, so that the light transmittance of the solar panel can be adjusted according to specific application scenarios and needs, and the decorative effect and energy efficiency can be balanced.

[0036] In one embodiment of the present application, a plurality of light-transmitting color blocks 221 are distributed in an array. On the one hand, the light-transmitting color blocks 221 distributed in an array help maximize the light-receiving area of ​​the solar panel, reduce the non-light-transmitting area, and thus improve the utilization rate of light; on the other hand, the plurality of light-transmitting color blocks 221 distributed in an array can create a regular visual effect, meet the requirements for aesthetics in modern architecture and design, and by adjusting the array density, size, and shape of the light-transmitting color blocks 221, a customized design can be performed according to different application scenarios and user needs.

[0037] In one embodiment of the present application, the light-transmitting color block 221 is one of a circular structure, a rectangular structure, an elliptical structure and a semicircular structure. Different shapes can meet different design requirements and provide users with personalized solar panel solutions. In addition, by selecting different shapes, the incident angle and distribution of light can be optimized according to the characteristics of the battery cell, thereby improving the photoelectric conversion efficiency. Of course, in other embodiments of the present application, a plurality of light-transmitting color blocks 221 can simultaneously have a circular structure, a rectangular structure, an elliptical structure and a semicircular structure. The mixed use of light-transmitting color blocks 221 of different shapes can create a colorful visual effect, meet different architectural styles and design requirements, increase the beauty and attractiveness of the product, and light-transmitting color blocks 221 of different shapes can be optimized according to the layout of the battery cell and the lighting conditions to maximize the light absorption efficiency. For example, a rectangular color block can be arranged at the edge area of ​​the solar cell panel 100, and a circular color block can be arranged in the central area.

[0038] In one embodiment of the present application, the light-transmitting color film 2 further includes a light-transmitting encapsulation layer 23, and the light-transmitting encapsulation layer 23 is connected to the side of the first light-transmitting pattern layer 22 that is away from the first light-transmitting connection layer 21. The light-transmitting encapsulation layer 23 can provide additional protection for the solar panel, help prevent environmental factors (such as dust, moisture, etc.) from damaging the first light-transmitting pattern layer 22 and the battery chip 1, protect the first light-transmitting pattern layer 22 from wear and fading, maintain the integrity and aesthetics of the pattern, and increase the service life of the solar panel 100. In addition, the light-transmitting encapsulation layer 23 can maintain good light transmittance while protecting the solar panel, ensuring that sunlight can effectively reach the battery chip 1.

[0039] In one embodiment of the present application, the light-transmitting encapsulation layer 23 includes a second light-transmitting connecting layer 231 and an encapsulation layer 232 which are stacked. The second light-transmitting connecting layer 231 is connected to the first light-transmitting pattern layer 22 on the side facing away from the encapsulation layer 232. The provision of the second light-transmitting connecting layer 231 enhances the connection strength between the first light-transmitting pattern layer 22 and the encapsulation layer 232, thereby making the interlayer bonding of the entire light-transmitting color film 2 more firm and improving the mechanical stability of the solar panel.

[0040] It should be noted that in one embodiment of the present application, the second light-transmitting connection layer 231 may be an EVE transparent adhesive film. The EVE (ethylene-vinyl acetate copolymer) transparent adhesive film has high transparency, which can ensure that most of the sunlight penetrates, thereby improving the photoelectric conversion efficiency of the solar panel. The EVE transparent adhesive film has good bonding and sealing properties, and can firmly connect the first light-transmitting pattern layer 22 and the encapsulation layer 232 to ensure the stability of the entire light-transmitting color film 2. The EVE transparent adhesive film usually has good waterproof properties, which can prevent moisture from penetrating into the battery chip 1 and protect the internal circuit from moisture. In other embodiments, the second light-transmitting connection layer 231 may also be a PET adhesive film or a silicone film.

[0041] In one embodiment of the present application, the solar panel 100 further includes a light-transmitting back sheet 4 and a third light-transmitting connection layer 3 which are stacked, and the side of the third light-transmitting connection layer 3 which faces away from the light-transmitting back sheet 4 is connected to the side of the light-transmitting color film 2 which faces away from the battery chip 1. The light-transmitting back sheet 4 provides additional structural support for the solar panel 100, increases the overall strength and stability, and helps to resist the influence of external forces and environmental factors (such as wind, snow, etc.). The material of the third light-transmitting connection layer 3 can refer to the material of the first light-transmitting connection layer 21 or the material of the second light-transmitting connection layer 231 described above.

[0042] In one embodiment of the present application, the solar panel 100 includes two light-transmitting color films 2, and the two light-transmitting color films 2 are respectively connected to two oppositely disposed side surfaces of the battery chip 1. The two light-transmitting color films 2 are respectively located on both sides of the battery chip 1, so that the solar panel 100 can absorb sunlight from two directions, thereby improving the overall energy output. In addition, the light-transmitting color films 2 on both sides can adopt the same or different designs, providing symmetrical or asymmetrical aesthetic effects. Through different designs of light-transmitting color films 2, the solar panel 100 can be more easily integrated with other building materials or decorative styles, thereby increasing the market diversity of the product.

[0043] See also Figure 4 The present invention also provides a solar panel assembly 200, which includes a plurality of solar panels 100. The specific structure of the solar panel 100 refers to the above embodiment. Since the solar panel assembly 200 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. Among them, the plurality of solar panels 100 are connected in sequence.

[0044] In one embodiment of the present application, the solar panel assembly 200 also includes a plurality of soft connecting wires 5, each of which is used to connect two adjacent solar panels 100. The soft connecting wires 5 are more flexible than hard connectors, and can adapt to slight displacements and deformations between solar panels 100, and are suitable for installation surfaces of different shapes and sizes. Moreover, through the soft connecting wires 5, multiple solar panels 100 can be folded and arranged, making the solar panel 100 assembly 200 more convenient to transport and carry, reducing the volume and weight. The foldable solar panel assembly 200 can be adjusted according to different usage requirements and environmental conditions, and is suitable for a variety of occasions.
