Description

Technical Field

[0001] This invention relates to the field of solar cell modules, specifically to an integrated vacuum-deposited solar cell module. Background Technology

[0002] Because the output voltage of a single solar cell is relatively low, and the electrodes of unencapsulated cells are prone to detachment due to environmental factors, a certain number of single cells must be sealed into a solar cell module by connecting them in series and parallel to prevent corrosion of the cell electrodes and interconnects. In addition, encapsulation also prevents the cells from breaking and facilitates outdoor installation. The quality of encapsulation determines the lifespan and reliability of the solar cell module.

[0003] Vacuum coating is a technology that uses physical methods to produce thin film materials. In a vacuum chamber, the atoms of the material are separated from the heating source and deposited onto the surface of the object being coated. This technology was first used to produce optical lenses, such as marine telescope lenses, and later extended to other functional films, such as aluminum plating on records, decorative coatings, and material surface modification, such as imitation gold plating on watch cases, coating of machine tools, and changing the red hardness of processing.

[0004] Most existing solar cell modules use a single piece of tempered glass as external protection. When light shines on a single piece of smooth glass, it is not easy to concentrate the light, resulting in uneven light dispersion, which affects the absorption of light by the solar cell module and reduces the power generation of the solar cell module. Summary of the Invention

By setting the tin-plated copper strips 13, the energy generated on each crystalline silicon solar cell 12 is collected and finally converged on the busbar 14, thus collecting and integrating all the energy.

[0034] Example 3:

[0035] like Figure 4 , Figure 5 and Figure 6 As shown, this embodiment of the invention provides an integrated vacuum-deposited solar cell module, which is further expanded based on the content of specific embodiment two:

[0036] The crystalline silicon solar cell 12 includes an upper solar panel 15. Multiple battery protrusions 17 are fixedly connected to the upper surface of the upper solar panel 15. A first insulating layer 16 is fixedly connected to the upper surface of the upper solar panel 15.

The lower surface of the lower solar panel 21 is fixedly connected to the third insulating layer 23.

[0040] Example 5:

[0041] like Figure 1-6 As shown, this embodiment of the invention provides an integrated vacuum-deposited solar cell module, which is further expanded based on the content of specific embodiment four:

[0042] The solar panel 8 is surrounded by a protective frame 24. Grooves are formed on all four sides of the inner wall of the protective frame 24. Sealing silicone 25 is fixedly connected to the inner wall of these grooves. The sealing silicone 25 fills the gaps between the tempered glass 1, the diffusing glass 2, the concentrating glass 5, the upper transparent protective plate 7, the solar panel 8, the lower transparent protective plate 9, and the backplate 10, creating a seal and preventing impurities from entering the gaps, thus affecting the device's use and increasing its lifespan. Both the upper transparent protective plate 7 and the lower transparent protective plate 9 are made of EVA material, forming the first insulating layer. 16. The second insulation layer 20 and the third insulation layer 23 are both made of PC material, and the protective frame 24 is made of aluminum alloy material. The advantages of EVA material are good water resistance, good corrosion resistance, non-toxic and odorless, good processability, good shock resistance, good elasticity, good thermal insulation, good sound insulation, and good toughness.

Aluminum alloy material has the advantages of low density, high strength, high strength of aluminum and aluminum alloy, good electrical and thermal conductivity, and corrosion resistance.

[0043] Working principle: Install the device at the location of use and connect the circuit in the device. Under the action of the sealing silicone 25, the edges of the gaps between the tempered glass 1, the diffusing glass 2, the focusing glass 5, and the upper transparent protective plate 7 are filled and sealed to prevent impurities from entering the gaps.

[0044] When light shines on tempered glass 1, the light passes through tempered glass 1 and enters diffuse glass 2. Under the action of multiple diffused grooves 3, the light is diffused, thus dispersing the light. At this time, the light shines through flat glass 4 onto focusing glass 5, and the light is focused through multiple focusing protrusions 6, so that the light passes through the upper transparent protective plate 7 and is focused on solar panel 8.

[0045] The crystalline silicon solar cells 12 on the solar panel 8 receive light energy, convert the light energy into electrical energy, and under the action of the tin-plated copper strip 13, the light energy is stored and collected in the busbar 14, and the collected energy is collected in the battery through the line.

[0046] When the crystalline silicon solar cell 12 receives solar energy, the upper solar panel 15 and the lower solar panel 21 conduct electrical energy, transmitting electrical energy in one direction. Under the action of the first insulating layer 16, the second insulating layer 20 and the lower solar panel 21, the upper solar panel 15 and the lower solar panel 21 are insulated and protected. The first insulating layer 16 increases the absorption and flow of current.
