Description

This double-sided adhesive buffer layer meets the requirements for light transmittance and electrical performance of photovoltaic encapsulation materials. The double-sided adhesive buffer layer on the front of the photovoltaic cell is transparent, while the double-sided adhesive buffer layer on the back is transparent or white; if white, it has high reflectivity. During the fully automated stacking process, using a buffer layer with a cushioning effect to replace the traditional lamination material can save lamination time and improve production efficiency. When the module is subjected to external force, the double-sided adhesive buffer layer can protect the cells. The white double-sided adhesive buffer layer in contact with the backsheet has high reflectivity, which can improve the module's output power.

[0023] Example 1

[0024] like Figure 1 As shown, this utility model provides a transparent photovoltaic panel encapsulation structure, including a light-transmitting backplate 1 and a light-transmitting panel 3. A solar cell 2 is disposed between the light-transmitting backplate 1 and the light-transmitting panel 3. The solar cell 2 facilitates the collection of solar energy for power generation. The cooperation between the light-transmitting backplate 1 and the light-transmitting panel 3 facilitates the protection of the solar cell 2 and ensures its stable use. The edges of the light-transmitting backplate 1 and the light-transmitting panel 3 are bonded together with sealant. This structure ensures good sealing between the light-transmitting backplate 1 and the light-transmitting panel 3, preventing dust from entering between them. Furthermore, the interior of the light-transmitting backplate 1 and the light-transmitting panel 3 is filled with a sealant. The sealant isolates the photovoltaic cell from external moisture, oxygen, dust, etc., preventing these substances from corroding and damaging the photovoltaic cell. Simultaneously, the sealant has high light transmittance, allowing more sunlight to pass through and reach the surface of the photovoltaic cell, thereby improving the photoelectric conversion efficiency of the photovoltaic panel. The structure consisting of the light-transmitting back panel 1, the light-transmitting panel 3, and the solar cell 2 is provided with a sleeve frame 4 on the outside to protect the edges of the light-transmitting back panel 1 and the light-transmitting panel 3, thus ensuring the stability of the entire photovoltaic panel.

[0025] like Figure 2As shown, the upper surface of the light-transmitting back panel 1 is provided with a mounting groove 11, which facilitates the installation of the solar cell 2 and ensures that the solar cell 2 is stably placed inside the mounting groove 11. A pressure groove 12 is provided at the top edge of the light-transmitting back panel 1, which facilitates the connection between the light-transmitting panel 3 and the light-transmitting back panel 1. A wire hole 13 is provided at the rear end of the light-transmitting back panel 1 for the wires of the solar cell 2 to pass through the light-transmitting back panel 1.

[0026] like Figure 3 As shown, a connecting wire 21 is provided at the bottom rear end of the solar cell 2. The connecting wire 21 passes through the wire hole 13 and protrudes from the light-transmitting back plate 1. A connecting plug 22 is provided at one end of the connecting wire 21 protruding from the light-transmitting back plate 1. The connection of the connecting wire 21 and the connecting plug 22 is to facilitate the discharge of electricity generated by the solar cell.

[0027] like Figure 4 As shown, the bottom surface of the light-transmitting panel 3 is provided with a pressure frame 31, and the bottom surface of the pressure frame 31 is provided with a transparent buffer strip 32. The pressure frame 31 and the transparent buffer strip 32 are pressed into the mounting groove 11. This structure facilitates a stable connection between the light-transmitting panel 3 and the light-transmitting back panel 1, and facilitates a good seal between the light-transmitting back panel 1 and the light-transmitting panel 3.

[0028] like Figure 5 As shown, the inner side of the socket frame 4 is provided with a slot 41, which facilitates good protection for the light-transmitting panel 3 and its edges. The back of the socket frame 4 is provided with a disassembly / removal port 42, which is used for disassembling and assembling various components with the socket frame 4.

[0029] Example 2

[0030] like Figure 1 and Figure 5 As shown, it also includes a junction box 5, which facilitates wiring and output of the generated power from the solar cell 2. The junction box 5 is inserted into the inside of the mounting / dismounting port 42, and the solar cell 2 is connected to the junction box 5. This structure allows the power generated by the solar cell 2 to be output to a designated location through the junction box 5. The back of the socket frame 4 has symmetrical connecting grooves 43 on both sides. The junction box 5 is threadedly connected to the connecting grooves 43 of the socket frame 4 via bolts passing through it. This structure ensures a stable connection between the socket frame 4 and the junction box 5.

[0031] like Figure 6As shown, the junction box 5 has a limiting baffle 51 at its outer end, which facilitates pressing against the socket frame 4. The junction box 5 has a connecting slot 52 at its inner end facing the socket frame 4. The connecting slot 52 facilitates connection between the junction box 5 and the solar cell 2. The bottom of the junction box 5 has a power transmission wire 53, and the end of the power transmission wire 53 has a power connector 54. The power transmission wire 53 and the power connector 54 facilitate the transmission of the electricity generated by the solar cell 2 to a designated location. The junction box 5 has symmetrical fixing feet 55 on both sides, and fixing holes 56 in the middle of the fixing feet 55. The fixing feet 55 and fixing holes 56 cooperate to facilitate fixing the junction box 5 with bolts.

[0032] When using the transparent photovoltaic panel encapsulation structure provided by this utility model, the solar cell 2 is placed in the mounting groove 11 and the mounting groove 11 is filled with encapsulant. Then, the light-transmitting panel 3 is pressed onto the light-transmitting back plate 1, and the light-transmitting back plate 1 and the transparent panel are sealed together with sealant. When installing the solar cell 2, the wires are passed through the wire hole 13. After the sealant has cured, the structure consisting of the light-transmitting back plate 1, the light-transmitting panel 3 and the solar cell 2 is embedded into the inner side of the socket frame 4. The junction box 5 is inserted into the disassembly port 42 so that the solar cell 2 is connected to the junction box 5, and the junction box 5 is fixed with bolts.

[0033] In summary, compared with the prior art, this application uses an adhesive bonding method to bond the light-transmitting backplate 1 and the light-transmitting panel 3 together, and the solar cell 2 is installed between the light-transmitting backplate 1 and the light-transmitting panel 3, which allows the solar cell 2 to be well sealed. An encapsulant is filled between the light-transmitting backplate 1 and the light-transmitting panel 3, ensuring sufficient stability of the solar cell 2 and also improving the encapsulation effect between the light-transmitting backplate 1 and the light-transmitting panel 3.

[0034] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
