Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, in particular to a one-way perspective solar cell panel. Background Art

[0002] Prolonged exposure to sunlight, intense light, and temperature fluctuations can easily cause changes in the physical and chemical properties of solar panels, leading to aging and a shortened lifespan. Furthermore, in low-latitude, humid regions, as well as windy, sandy, and snowy areas, prolonged rain, sand, or snow can easily obstruct solar panels, causing hot spots on the cells. These factors can also shorten the lifespan of solar panels.

[0003] To this end, a one-way perspective solar cell panel is provided to solve the above technical problems. Utility Model Content

[0004] The purpose of the utility model is to provide a one-way perspective solar cell panel to solve the problems existing in the above-mentioned prior art.

[0005] To achieve the above-mentioned objectives, the present invention provides a one-way perspective solar cell panel, comprising a laminate and a frame arranged at the edge of the laminate, wherein the laminate comprises a cover glass, a first packaging film, a cell string, a second packaging film and a back glass arranged in sequence, and the cover glass is a one-way perspective glass.

[0006] Preferably, the light transmittance of the one-way vision glass is 20% to 50%.

[0007] Preferably, the reflectivity of the one-way vision glass is not less than 90%.

[0008] Compared with the prior art, the present invention has the following advantages and technical effects:

[0009] The one-way perspective solar panel provided by the utility model can control the amount of sunlight irradiating the battery string by setting the cover glass as one-way perspective glass, reduce the amplitude of changes in light and temperature, and thus slow down the aging rate of the material; and when there are obstructions, the cover glass reflects part of the light and controls the incident light, making it difficult for local heating to occur, resulting in the occurrence of hot spots, thereby helping to extend the service life of the solar panel.

[0013] It should be noted that, unless there is a conflict, the embodiments and features of the embodiments of the present invention may be combined with each other. The embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments obtained by persons of ordinary skill in the art without creative effort are within the scope of protection of the present invention. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0014] like Figure 1 As shown, the utility model provides a one-way perspective solar cell panel, including a laminate and a frame 1 arranged at the edge of the laminate, the laminate includes a cover glass 2, a first packaging film 3, a battery string 4, a second packaging film 5 and a back glass 6 arranged in sequence, and the cover glass 2 is a one-way perspective glass.

[0015] According to further optimization scheme, the light transmittance of one-way vision glass is 20% to 50%.

[0016] Further optimization of the solution will ensure that the reflectivity of the one-way vision glass is not less than 90%.

[0017] The one-way perspective solar panel provided by the present invention can control the amount of sunlight irradiating the battery string 4 under sunlight through the setting of the one-way perspective glass, reduce the amplitude of changes in light and temperature, and thus slow down the aging speed of the material; through the setting of the one-way perspective glass, the solar panel is exposed to sunlight for a long time, and since it only absorbs part of the light, it is difficult to cause changes in the physical and chemical properties of its material; and after the light passing through the cover glass 2 is irradiated on the back glass 6, a part of it directly passes through the back glass 6, and the other part will be reflected to the cover glass 2. At this time, the cover glass 2 is in an opaque state, in a mirror-like state, and reflects the light to the battery string 4 again, thereby reducing the impact of the one-way perspective glass on the power generation efficiency, and when there are obstructions, it is difficult to cause local heating and the occurrence of hot spot phenomenon by utilizing the cover glass 2 to reflect part of the light and control the incident light.

[0018] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
