[0002] As a key device for converting solar energy into electricity, photovoltaic (PV) modules have always been a focus of industry attention due to their superior power generation performance. A PV module generally consists of a solar panel and a frame. While the solar panel is the core component, its performance is also affected by the surrounding frame. For example, the frame, while tightly fitted to the edge of the solar panel to ensure structural stability, unintentionally creates some shading around the panel. This shading directly weakens the light absorption capacity of the area on the back of the module, thus reducing the power generation from the back of the module. Utility Model Content

[0019] In one embodiment, the border sub-body includes:

[0020] Sub-body side plate, which is connected to the main body side plate;

[0022] The main body base plate, the sub-body side plate, the sub-body base plate, and the sub-body connecting plate together form an insertion cavity.

[0023] In one embodiment, the inner side of the sub-body base plate is provided with a connection position, and the inner side of the sub-body base plate is divided into a first plate area and a second plate area based on the connection position. The first plate area is located inside the insertion cavity, and the second plate area is located outside the insertion cavity. The sub-body connecting plate is connected to the connection position of the sub-body base plate. The inner side of the sub-body connecting plate faces the insertion cavity, and the outer side of the sub-body connecting plate faces away from the insertion cavity.

Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0052] See Figure 1 As shown, this application provides a photovoltaic module, which includes a module frame and a photovoltaic panel 100 assembled within the module frame, as shown. Figure 1 The top view shown indicates the front orientation of the photovoltaic panel 100, as shown below. Figure 1 The image below shows the back of the photovoltaic panel 100. The module frame includes a frame assembly 1000 and a thermoluminescent element 2000. The frame assembly 1000 can be made of materials such as aluminum alloy. The frame assembly 1000 has an inner frame space 1001 for assembling the photovoltaic panel 100 of the photovoltaic module. (Continue reading...) Figure 1As shown, a thermoluminescent element 2000 is disposed on the frame assembly 1000. The thermoluminescent element 2000 is made of a thermoluminescent material, which can be a material doped with rare earth elements, such as lithium fluoride. The light excitation threshold temperature of lithium fluoride is 50°C. In addition, other materials with thermoluminescent properties can also be selected as thermoluminescent materials.

[0053] The thermoluminescent material 2000 can be configured in various shapes, structures, and sizes according to requirements. For example, the thermoluminescent material 2000 can have a layered structure with a large surface area, and its thickness can be between 0.001 mm and 1 mm. A light-transmitting protective layer 3000 can also be provided on the outer layer of the thermoluminescent material 2000. For example, a light-transmitting protective layer 3000 can be coated or bonded to the outer layer of the thermoluminescent material 2000. The light-transmitting protective layer 3000 can be made of transparent silicone material. Alternatively, other materials with high transparency and high weather resistance can be selected for the light-transmitting protective layer 3000, and its thickness can range from 0.01 mm to 2 mm.

[0054] The light energy excited by the thermoluminescent material 2000 can be designed to be directed towards the photovoltaic panel 100 located within the frame space 1001. In one embodiment, when the photovoltaic module is operating outdoors, the solar irradiance illuminating the module frame and the heat from the photovoltaic module itself will heat the module frame, causing its temperature to rise. Especially at noon, the temperature of the module frame is very high, and the high temperature will excite the thermoluminescent material to continuously emit light. The excited light energy will then be directed towards the photovoltaic panel 100. In one embodiment, the light energy excited by the thermoluminescent material 2000 can be configured to be directed towards the back of the photovoltaic panel 100 located within the frame space 1001, thereby increasing the incident light energy on the back of the photovoltaic module, thus improving the power generation performance of the photovoltaic module and reducing the shading of the back of the photovoltaic module by the module frame.

[0055] The design of this type of component frame will not affect the heat dissipation of the photovoltaic module. Moreover, according to the law of conservation of energy, the design of this type of component frame is actually beneficial to the heat dissipation of the photovoltaic module to a certain extent.

[0056] The shape, size, and structure of the space 1001 within the frame can be customized to accommodate the photovoltaic panel 100 to be installed, ensuring smooth installation. Furthermore, the photovoltaic panel 100 can be installed using various methods such as snap-fit, adapter, or plug-in; no specific method is limited here. Figure 2As shown, in one embodiment, the frame assembly 1000 includes a frame main body 1100 and a frame sub-body 1200. The frame main body 1100 has an annular structure. The annular frame main body 1100 can be used to enclose the aforementioned inner frame space 1001 inside it, and to assemble the photovoltaic panel 100 inside the frame main body 1100. The inner annular side of the frame main body 1100 can be provided with an assembly groove 1101. The assembly groove 1101 is used to assemble the photovoltaic panel 100, that is, to insert the annular circumference of the photovoltaic panel 100 into the assembly groove 1101, thereby realizing the assembly of the photovoltaic panel 100 inside the frame main body 1100.

[0057] In one embodiment, the frame body 1100 includes a main bottom plate 1110, a main side plate 1120, and a main top plate 1130. The main side plate 1120 is connected to the main bottom plate 1110, and the main top plate 1130 is connected to the main side plate 1120. For example, one side of the main bottom plate 1110 is connected to one side of the main side plate 1120, and one side of the main top plate 1130 is connected to the other side of the main side plate 1120. Thus, the main top plate 1130, the main side plate 1120, and the main bottom plate 1110 enclose and form an assembly groove 1101. The assembly groove 1101 is an annular groove that surrounds the frame body 1100 and is used to surround the photovoltaic panel 100 around its annular circumference.

[0058] The photovoltaic panel 100 can be bonded and fixed to the frame body 1100 by adhesive injected into the assembly groove 1101. For example, in one embodiment, the main body top plate 1130 is provided with an overflow groove 1131, which is located inside the assembly groove 1101, thereby allowing overflow adhesive to be processed. In addition, the main body top plate 1130 may also be provided with a guide slope 1132, which is located outside the assembly groove 1101.

[0059] The frame sub-body portion 1200 is connected to the frame main body portion 1100. A thermoluminescent material 2000 is disposed on the frame sub-body portion 1200, thereby assembling the thermoluminescent material 2000 adjacent to the photovoltaic panel 100 via the frame sub-body portion 1200. For example, the thermoluminescent material 2000 can be assembled adjacent to the photovoltaic panel 100 at a certain angle, facilitating the directing of more light energy excited by the thermoluminescent material onto the photovoltaic panel 100. In one embodiment, the frame sub-body portion 1200 includes a sub-body connecting plate 1210, which is connected to the main body base plate 1110. The thermoluminescent material 2000 is disposed on the sub-body connecting plate 1210, for example, on the outer surface of the sub-body connecting plate 1210.

[0060] Continue reading Figure 2As shown, in one embodiment, the frame sub-body 1200 includes a sub-body side plate 1220 and a sub-body bottom plate 1230. The sub-body side plate 1220 is connected to the main body side plate 1120, and the sub-body bottom plate 1230 is connected to the sub-body side plate 1220 and the sub-body connecting plate 1210. The main body bottom plate 1110, the sub-body side plate 1220, the sub-body bottom plate 1230, and the sub-body connecting plate 1210 together form an insertion cavity. For example, one side of the sub-body side plate 1220 is connected to one side of the main body side plate 1120, and the two can be in the same plane, or they can be integrally formed into a single plate structure. One side of the sub-body bottom plate 1230 is connected to one side of the sub-body side plate 1220.

[0061] In one embodiment, a connection position 1231 may be provided on the inner side of the sub-body base plate 1230. The connection position 1231 may be located approximately in the middle of the sub-body base plate 1230, thereby dividing the inner side of the sub-body base plate 1230 into a first plate area 1232 and a second plate area 1233 based on the connection position 1231. The area ratio of the first plate area 1232 and the second plate area 1233 can be determined according to actual needs. The first plate area 1232 is located inside the insertion cavity, and the second plate area 1233 is located outside the insertion cavity. At this time, the sub-body connecting plate 1210 is connected to the connection position 1231 of the sub-body base plate 1230. The inner side of the sub-body connecting plate 1210 faces the insertion cavity, and the outer side of the sub-body connecting plate 1210 faces away from the insertion cavity. The thermoluminescent element 2000 is disposed on the outer side of the sub-body connecting plate 1210 and the second plate area 1233 of the sub-body base plate 1230.

[0062] like Figure 2 or Figure 3 As shown, in one embodiment, the sub-body connecting plate 1210 can be designed to be inclined relative to the main body base plate 1110. This inclination allows the outer surface of the sub-body connecting plate 1210 to face the inner space 1001 of the frame assembly 1000 to a certain extent. This ensures that the portion of the thermoluminescent element 2000 located on the outer surface of the sub-body connecting plate 1210 is oriented towards the photovoltaic panel 100 as much as possible. Those skilled in the art can adjust the inclination angle of the sub-body connecting plate 1210 relative to the main body base plate 1110 according to actual needs. Alternatively, as... Figure 4 As shown, the outer surface of the sub-body connecting plate 1210 can also be set as an arc surface. In addition, it can also be set as other structures that facilitate the projection of light energy excited by the thermoluminescent material onto the back of the photovoltaic panel 100. The specific angle of the slope or the arc surface structure can be designed according to the actual situation of the component frame (such as size and shape), and is not limited here.

[0063] Continue reading Figures 2 to 4As shown, the second plate area 1233 of the sub-body base plate 1230 can also face the inner space 1001 of the frame of the frame assembly 1000 simultaneously with the design of the sub-body connecting plate 1210. In addition, the second plate area 1233 of the sub-body base plate 1230 is set as an arc surface with the design of the sub-body connecting plate 1210. The matching design of the sub-body connecting plate 1210 and the sub-body base plate 1230 is to direct as much of the light energy excited by the thermoluminescent material as possible to the back of the photovoltaic panel 100. Those skilled in the art can design the structure of the sub-body connecting plate 1210 and the sub-body base plate 1230 according to actual needs, which is not limited here.

[0064] The outer side of the sub-body connecting plate 1210 is provided with a clearance groove 1211, and the second plate surface area 1233 of the sub-body base plate 1230 is provided with screw holes 1212. Therefore, if Figure 4 As shown, the clearance groove 1211 can be used to avoid the screw hole 1212. This design provides sufficient space for opening the screw hole 1212 to ensure the load-bearing capacity of the photovoltaic module.

[0065] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
