Technical Field
[0001] The utility model belongs to the technical field of curved photovoltaics, and in particular relates to an anti-glare curved photovoltaic component. Background Art
[0002] Solar energy is a renewable, clean energy source that is not restricted by geographical location. In recent years, with the development of photovoltaic technology, the cost of photovoltaic power generation has dropped rapidly, photovoltaic power generation technology has been used on an increasingly large scale, and the combination of photovoltaics and buildings has also become one of the areas of photovoltaic application.
[0003] Building-integrated photovoltaics (BIPV) is a technology that integrates photovoltaic products into buildings, using photovoltaic power generation devices as an integral building component to replace some building materials. With the continuous development of building-integrated photovoltaics, the demand for curved photovoltaic modules is also increasing.
[0004] The existing curved photovoltaic modules have a smooth front surface with high reflectivity. When sunlight hits the module surface in a relatively strong light environment, it is easy to produce severe glare due to the strong specular reflection, causing visual discomfort. In some specific areas with high requirements for light pollution environment, such as highways, airports, and building curtain walls, glare is the focus of design. In order to ensure the safety of personnel and the surrounding environment and reduce the harm caused by glare, anti-glare glass and anti-glare components are increasingly used in such occasions. Utility Model Content
[0005] The utility model aims to provide an anti-glare curved photovoltaic module to solve the technical problem that the mirror reflection is strong and easily produces serious glare, thus causing visual discomfort, so as to achieve the purpose of anti-glare and improve power generation.
[0006] In order to solve the above technical problems, the utility model provides an anti-glare curved photovoltaic module, including:
[0007] Anti-glare curved front panel, front adhesive film layer, power generation unit layer, back adhesive film layer and curved back panel;
[0008] The anti-glare curved front panel is wavy in shape, and an anti-glare pattern layer is arranged on the outward side of the anti-glare curved front panel, wherein the anti-glare pattern layer is composed of a plurality of continuous convex patterns.
[0009] Furthermore, the anti-glare pattern layer is arranged at the crest of the anti-glare curved front panel.
[0010] Furthermore, the anti-glare curved front panel adopts high-transmittance curved glass.
[0011] Furthermore, the plurality of convex patterns are in the form of continuous triangles, diamonds or irregular shapes.
[0012] Furthermore, the power generation unit layer is composed of a plurality of power generation chip bodies.
[0013] Furthermore, the power generation chip body adopts some crystalline silicon or amorphous silicon.
[0014] Furthermore, the length of the power generation chip body is less than half of the chord length of the anti-glare curved front panel.
[0015] Furthermore, the curved back panel is made of one of a back panel and glass.
[0016] The beneficial effects of the utility model are:
[0017] 1. By providing an anti-glare pattern layer in the crest area, it can not only play an anti-glare role, but also the internal structure of the anti-glare pattern layer can reflect the outward reflected light back to the battery area to increase power generation.
[0018] 2. The anti-glare pattern is a continuous convex pattern with a smooth surface, which can prevent dust accumulation; the continuous convex pattern forms a drainage path, which can play a role in drainage.
[0019] 3. The anti-glare curved front panel is still smooth in the trough area at a relatively low point, so water will not accumulate in heavy rain and it can play a role in drainage. At the same time, the smooth surface is not easy to accumulate dust, reducing the loss of power generation caused by dust accumulation.

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] Example:
[0033] like Figures 1 to 3 As shown, an anti-glare curved photovoltaic module includes: an anti-glare curved front panel 1, a front adhesive film layer 2, a power generation unit layer 3, a back adhesive film layer 4 and a curved back panel 5, which are all laminated in sequence. In this embodiment, the anti-glare curved front panel 1 is made of high-transmittance curved glass. The curved back panel 5 is made of one of a back panel or glass.
[0034] like Figures 1 to 3 As shown, the anti-glare curved front panel 1 is wavy, and an anti-glare pattern layer 11 is provided on the outward side of the anti-glare curved front panel 1, and the anti-glare pattern layer 11 is composed of a plurality of continuous convex patterns 12. The anti-glare pattern layer 11 plays an anti-glare role, and at the same time, the pattern of the anti-glare pattern layer 11 can make the incident and reflected light reflect inward again through the outermost convex patterns, thereby improving the overall power generation of the photovoltaic module.
[0035] The anti-glare pattern layer 11 is arranged at the crest of the anti-glare curved front panel 1. The crest is a high point, and a drainage path is formed through continuous protrusions, which can play a role in drainage. The smooth texture of the anti-glare pattern layer 11 plays a role in dust prevention. The trough is a smooth anti-glare curved front panel 1, which retains the original drainage effect and is not easy to accumulate dust.
[0036] In this embodiment, the plurality of convex patterns are in the shape of continuous triangles, diamonds or irregular shapes.
[0037] like Figures 1 to 3As shown, the power generation unit layer 3 is composed of a plurality of power generation chip bodies 31. In this embodiment, the power generation chip bodies 31 are made of a plurality of crystalline silicon or amorphous silicon. The length of the power generation chip body 31 is less than half of the chord length of the anti-glare curved front panel 1.
[0038] In summary: by providing an anti-glare pattern layer 11 in the wave crest area, it can not only play an anti-glare role, but also the internal structure of the anti-glare pattern layer 11 can reflect the outwardly reflected light back to the cell area to increase power generation. The anti-glare pattern is a continuous convex pattern with a smooth surface, which plays a role in preventing dust accumulation; the continuous convex pattern forms a drainage path, which can play a role in drainage. The anti-glare curved front panel 1 is still a smooth surface in the relatively low trough area, which will not accumulate water in heavy rain weather and can play a role in drainage. At the same time, the smooth surface is not easy to accumulate dust, reducing the power generation loss caused by dust accumulation.
