[0039] Photovoltaic modules are generally composed of laminates and photovoltaic frames used to install the laminates. Among them, the photovoltaic frame, as an important component of the photovoltaic module, plays the role of fixing and sealing the laminates and facilitating the transportation and installation of the photovoltaic module. The frame structure of the photovoltaic module has a great impact on the installation and service life of the photovoltaic module.

[0040] In the related art, photovoltaic frames generally have an A-side structure. When the laminate is installed on such a photovoltaic frame, the A-side will be higher than the light-receiving surface of the laminate. Due to the obstruction of the A-side, the laminate will accumulate more dust during long-term use, which is difficult to clean and affects the power generation efficiency of the photovoltaic module.

[0041] In view of the above problems, please refer to Figures 1, 2 and 3. The embodiment of the present application relates to a photovoltaic frame 10 for installing a laminate 800. Specifically, the laminate 800 includes a front glass, an intermediate layer and a back glass stacked in sequence, and the side of the back glass away from the intermediate layer is a light-receiving side. The side of the front glass away from the intermediate layer is a backlight side. The intermediate layer includes a first adhesive film, a battery cell and a second adhesive film stacked in sequence.

[0042] Among them, the materials used for the first film and the second film include but are not limited to: ethylene-vinyl acetate copolymer (EVA), polyolefin elastomer (POE), polyvinyl butyral (PVB), EPE (EVA-POE-EVA), EP (EVA-POE) or PEP (POE-EVA-POE).

[0043] The types of solar cells include but are not limited to Passivated Emitter Rear Cell (PERC), Tunnel Oxide Passivated Contact (TOPCon), Heterojunction with Intrinsic Thin-film (HJT), Interdigitated Back Contact (IBC), Perovskite cells, etc.

[0044] For PERC cells, along the thickness direction, PERC cells include the front surface metal silver electrode, the front surface silicon nitride passivation layer, the phosphorus layer emitter, the P-type base silicon layer, the local aluminum back field, the metal aluminum back electrode, and the back passivation layer (Al2O3 / SiNx). PERC cells use a passivation film to passivate the back, replacing the full aluminum back field, enhancing the internal back reflection of light in the silicon base, reducing the recombination rate on the back, and increasing the efficiency of the cell by 0.5%-1%.

[0045] For TOPCon cells, along the thickness direction, TOPCon cells include metal silver electrodes, front surface silicon nitride passivation layers, boron-doped emitters, N-type base silicon layers, diffused doping layers, ultra-thin silicon oxide, doped polysilicon, silicon nitride, and metal silver electrodes. The back of the cell is composed of an ultra-thin silicon oxide layer (1nm~2nm) and a phosphorus-doped microcrystalline amorphous mixed Si film, which together form a passivation contact structure. This structure can block the recombination of minority carrier holes and increase the open circuit voltage and short circuit current of the cell. The ultra-thin oxide layer allows majority electrons to tunnel into the polysilicon layer while blocking the recombination of minority carrier holes. The good passivation effect of ultra-thin silicon oxide and heavily doped silicon film causes the energy band on the silicon wafer surface to bend, thereby forming a field passivation effect, greatly increasing the probability of electron tunneling, and reducing the contact resistance, which increases the open circuit voltage and short circuit current of the cell, thereby improving the cell conversion efficiency.

[0046] For HJT cells, along the thickness direction, the HJT cells include a front low-temperature silver electrode, a front conductive film, an N-type amorphous silicon film, an intrinsic amorphous silicon film, an N-type base silicon layer, an intrinsic amorphous silicon film, a P-type amorphous silicon film, a back conductive film, and a back low-temperature silver electrode.

[0047] For IBC cells, along the thickness direction, IBC cells include silicon nitride anti-layer, N+ front surface field, N-type base silicon layer, P+ emitter, N+ back field, aluminum oxide passivation layer, silicon nitride anti-reflection layer, and metal silver electrode. IBC cells use ion implantation technology to obtain P and N regions with good uniformity and precisely controllable junction depth. There is no grid line blocking on the front of the cell, which can eliminate the shading current loss of the metal electrode and achieve the maximum utilization of incident photons. The short-circuit current can be increased by about 7% compared with conventional solar cells; due to the back contact structure, there is no need to consider the grid line blocking problem, and the grid line ratio can be appropriately widened, thereby reducing the series resistance and having a high fill factor; the surface passivation and surface light trapping structure can be optimized to obtain a lower front surface recombination rate and surface reflection.

[0048] For perovskite cells, along the thickness direction, the perovskite cell includes substrate material, conductive film, electron transport layer (titanium dioxide), perovskite absorption layer (hole transport layer), and metal cathode. Perovskite materials have a high light absorption coefficient and a long carrier diffusion distance. After the photons absorbed by the perovskite material are converted into electrons, they are easily collected by the electrode with low loss, so they can generate higher photoelectric voltage and current, making perovskite show higher photoelectric conversion efficiency.

[0049] 1 , 2 and 3 , the photovoltaic frame 10 includes a carrier plate 100 , a first side plate 200 and a second side plate 300 . The carrier plate 100 is used to support the backlight surface of the laminate 800 . The carrier plate 100 has a carrier surface. The carrier surface is used to support the backlight surface of the laminate 800 .

[0050] The first side plate 200 and the second side plate 300 are respectively located on opposite sides of the carrier plate 100. The first side plate 200, the second side plate 300 and the carrier plate 100 are all configured to extend longitudinally along the length direction of the photovoltaic frame 10, the first side plate 200 has a first extension portion 210 extending toward the bearing surface, and the side of the carrier plate 100 close to the first side plate 200 has a second extension portion 110 extending toward the bearing surface. The first extension portion 210 and the carrier plate 100 are surrounded to form a mounting groove 400, and the mounting groove 400 is used to accommodate the laminate 800. The first extension portion 210 is used to abut the side of the laminate 800. The end of the laminate 800 can be carried in the installation groove 400, so that the laminate 800 can be pre-installed on the bearing surface by shelving, lapping, etc.

[0051] The laminate 800 is supported by the supporting plate 100. When the laminate 800 needs to be installed on the photovoltaic frame 10, a preset amount of sealant 900 can be filled in the installation groove 400, and the laminate 800 can be glued and fixed in the installation groove 400 by the sealant 900 to achieve fixed installation of the laminate 800 on the photovoltaic frame 10.

[0052] Referring to FIGS. 1, 2 and 3, a first rubber baffle plate 220 is disposed at the end of the first extension 210 away from the bearing surface. A second rubber baffle plate 120 is disposed at the end of the second extension 110 away from the bearing surface. Both the first rubber baffle plate 220 and the second rubber baffle plate 120 extend toward the inside of the mounting groove 400. A bent portion is formed at one end of the first rubber baffle plate 220 away from the first extension 210, and the bent portion wraps around one end of the second rubber baffle plate 120 away from the second extension 110.

[0053] Specifically, the first extension portion 210 and the second extension portion 110 are perpendicular to the carrier plate 100. The first adhesive plate 220 is perpendicular to the first extension portion 210 and is horizontal to the carrier plate 100. The second adhesive plate 120 is perpendicular to the second extension portion 110 and is horizontal to the carrier plate 100. The first extension portion 210, the second extension portion 110, the first adhesive plate 220 and the second adhesive plate 120 are all configured to extend longitudinally along the length direction of the photovoltaic frame 10. That is, the first side plate 200, the second side plate 300, the carrier plate 100, the first extension portion 210, the second extension portion 110, the first adhesive plate 220 and the second adhesive plate 120 all extend in a direction perpendicular to the paper surface.

[0054] The end of the first rubber baffle plate 220 away from the first extension portion 210 is bent toward the inside of the installation groove 400 at an angle of 180°. The end of the second rubber baffle plate 120 away from the second extension portion 110 is not bent toward the inside of the installation groove 400.

[0055] By setting a bending portion at one end of the first adhesive baffle plate 220 away from the first extension portion 210, and the bending portion wraps one end of the second adhesive baffle plate 120 away from the second extension portion 110, the connection between the first adhesive baffle plate 220 and the second adhesive baffle plate 120 can be made tighter, thereby improving the firmness of the photovoltaic frame 10.

[0056] Please refer to Figures 1, 2 and 3. The side of the carrier plate 100 close to the second side plate 300 has a support plate 130 extending out of the second side plate 300 toward the second side plate 300. The support plate 130 is used to support the backlight surface of the laminate 800. By setting the support plate 130 to extend out of the second side plate 300, the contact area between the sealant 900 and the laminate 800 can be increased, and the force transmitted to the second side plate 300 is small, which prevents the second side plate 300 from deforming, bending, or even breaking in the process of supporting the laminate 800 for a long time, thereby improving the service life of the photovoltaic frame 10.

[0057] When the laminate 800 is installed on the installation groove 400, the top of the first adhesive baffle 220 is flush with the light-receiving surface of the laminate 800. By setting the top of the first adhesive baffle 220 to be flush with the light-receiving surface of the laminate 800, dust accumulated on the light-receiving surface of the laminate 800 is easy to clean, and the photovoltaic frame 10 will not block the light-receiving surface of the laminate 800, thereby improving the power generation efficiency of the laminate 800.

[0058] Please refer to Figures 1, 2 and 3. According to some embodiments of the present application, optionally, the first extension portion 210 and the second extension portion 110 are tightly fitted, and the first rubber baffle plate 220 and the second rubber baffle plate 120 are tightly fitted, which can be convenient for production and manufacturing. During production and manufacturing, there is no need to consider the spacing between the first extension portion 210 and the second extension portion 110, and between the first rubber baffle plate 220 and the second rubber baffle plate 120.

[0059] Please refer to FIG. 1 , FIG. 2 and FIG. 3 . According to some embodiments of the present application, optionally, a first glue overflow groove 500 is formed between the carrier plate 100 , the second extension portion 110 and the second glue baffle plate 120 , and the first glue overflow groove 500 is connected to the installation groove 400 .

[0060] The laminate 800 is bonded to the carrier plate 100, the second extension 110 and the second adhesive baffle 120 by adhesive. The first adhesive overflow groove 500 can be used for filling the adhesive and controlling the adhesive overflow. The adhesive can be filled into the first adhesive overflow groove 500. The adhesive bonds the side of the laminate 800 to the side of the second extension 110 and the laminate 800 to the bearing surface of the carrier plate 100. After the adhesive is cured, the laminate 800 is glued and fixed in the installation groove 400, so that the laminate 800 is fixedly installed on the photovoltaic frame 10.

[0061] And because the adhesive is fluid, under the action of gravity of the laminate 800, the adhesive is squeezed and evenly coated on the gaps between the laminate 800 and the second adhesive baffle 120, the laminate 800 and the second extension 110, and the laminate 800 and the carrier plate 100. The overflow groove can accommodate excess adhesive to prevent excess adhesive from overflowing to the surface of the laminate 800, thereby avoiding the adhesive from blocking the surface of the laminate 800, thereby ensuring that the surface of the laminate 800 has a higher power generation efficiency.

[0062] Please refer to Figures 1, 2 and 3. According to some embodiments of the present application, optionally, one end of the first glue baffle 220 away from the first extension portion 210 is bent toward the inside of the installation groove 400 to form a glue overflow protrusion 221 for preventing the sealant 900 from overflowing, so that the adhesive can be contained in the first glue overflow groove 500 as much as possible, which can prevent the adhesive in the first glue overflow groove 500 from overflowing to the outside during the pressure process, and ensure that the adhesive in the first glue overflow groove 500 is used as much as possible for bonding the laminate 800, thereby improving the bonding strength of the laminate 800 on the photovoltaic frame 10.

Specifically, the second glue overflow groove 140 is a wedge-shaped groove, the adhesive can quickly flow into the second glue overflow groove 140, and the contact area between the adhesive and the laminate 800 can be increased, while the problem of poor glue overflow can be avoided, and the overall bearing capacity of the photovoltaic frame 10 can be improved.

[0064] The second glue overflow groove 140 can be used to accommodate the adhesive, and the second glue overflow groove 140 is connected to the installation groove 400. When the laminate 800 needs to be fixed on the photovoltaic frame 10, the adhesive in the second glue overflow groove 140 can flow into the installation groove 400 to glue and fix the laminate 800 to the photovoltaic frame 10, further improving the bonding strength of the laminate 800 on the photovoltaic frame 10.

[0065] Referring to Figures 1, 2 and 3, according to some embodiments of the present application, optionally, the distance between the end surface of the support plate 130 away from the carrier plate 100 and the second side plate 300 is 4mm-6mm. Optionally, the distance between the end surface of the support plate 130 away from the carrier plate 100 and the second side plate 300 is 5mm.

The second horizontal plate is connected to an end of the second side plate 300 close to the bearing plate 100, and chamfers are provided between the first horizontal plate and the vertical plate, and between the vertical plate and the second horizontal plate.

[0067] By setting chamfers between the first horizontal plate and the vertical plate and between the vertical plate and the second horizontal plate, the supporting strength of the support plate 130 can be improved, and the second side plate 300 can be further prevented from being deformed, bent, or even broken during long-term support of the laminate 800, thereby increasing the service life of the photovoltaic frame 10.

The bottom plate 600, the carrier plate 100, the first side plate 200 and the second side plate 300 are connected as a whole through the angle code, and the cavity 700 can be used for the locking operation of the angle code, so as to facilitate the fixed connection between the bottom plate 600, the carrier plate 100, the first side plate 200 and the second side plate 300 through the angle code.

[0069] Among them, a plurality of grooves 230 are provided on the end surface of the first side plate 200 away from the cavity 700, and the plurality of grooves 230 are arranged at intervals along the extension direction of the first side plate 200.
