Description

Technical Field

[0001] The utility model relates to the technical field of light-splitting structure films, and more specifically to a light-splitting structure film for improving the utilization rate of photovoltaic gap light. Background Art

[0002] Beam-splitting film is a thin film material with unique optical properties. Typically composed of multiple layers of materials with varying refractive indices, this film is precisely designed and fabricated to create a unique optical structure. This structure selectively reflects, refracts, or transmits incident light, thereby separating and directing light of different wavelengths. By selectively separating and directing light of different wavelengths, this beam-splitting film redistributes interstitial light that would otherwise be wasted back to the photovoltaic cells, thereby improving the light utilization efficiency of the photovoltaic system.

[0003] For example, a prior art disclosure number CN218298563U is a spectroscopic film structure. In this utility model, light is incident from the light incident surface, first passes through the prism structure in the first structural layer, and is refracted in a direction perpendicular to the prism structure surface by the action of the prism structure, then passes through the substrate layer, and finally passes through the conical structure of the second structural layer. The light is refracted and split by multiple identical conical surfaces of the conical structure, and the focused light is dispersed and split, thereby playing a spectroscopic function.

[0004] However, the above-mentioned existing technology still has the following problems when in use: when the traditional splitting structure film is in use, the light continues to be directed to the reflective film after being reflected by the glass. At this time, part of the light can no longer be reflected to the surface of the battery. The light will continue to be reflected multiple times between the reflective film and the glass and lost. Based on this, the utility model provides a splitting structure film that improves the utilization rate of photovoltaic gap light. Utility Model Content

[0010] In a preferred embodiment, silicone plates are fixedly bonded inside the two grooves 2 at the bottom of the EVA film, and the cross-section of the silicone plates is set to be wavy. The impact resistance of the glass film 1 can be improved by means of the silicone plates.

[0011] In a preferred embodiment, the outer wall surfaces of the bottom of the two silicone plates are both reflective surface 2, and each reflective surface 1 and each reflective surface 2 are coated with an aluminum paint layer.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Refer to the instruction manual Figure 1-5The present invention provides a light-splitting structure film for improving the utilization rate of photovoltaic gap light, including a light-splitting structure film body 1, wherein the light-splitting structure film body 1 includes a glass film 1 101 and a glass film 2 102 distributed above and below. The glass film 101 and the glass film 102 both have the functions of protection and light transmission, thereby increasing the service life of the light-splitting structure film body 1. An EVA film 103 is fixedly bonded to the bottom end of the glass film 101. Specifically, the EVA film 103 has the advantages of being resistant to aging and UV light, thereby extending its service life. A plurality of power generation panels 104 are provided on the top of the glass film 2 102, and a gap groove 105 is formed between two adjacent power generation panels 104.

[0025] The bottom end of the EVA film 103 and the inside of the gap groove 105 are fixedly bonded with a gap splitter film 2, and the gap splitter film 2 includes a substrate 201. Two substrates 201 are fixedly bonded with multiple prisms 202 on the surface close to each other. One side wall of each prism 202 is a light-transmitting surface 203, and the other side wall of each prism 202 is a reflective surface 204.

[0026] The light-splitting structure film body 1 is composed of the glass film 101, the EVA film 103, the power generation cell panel 104 and the glass film 2 102. The light is irradiated downward to the substrate 201 through the glass film 101, and after passing through the substrate 201 and irradiating the reflective surface 1 204 on the prism 202, the light is reflected to the transparent surface 203, and then the light is irradiated to the surface of the power generation cell panel 104 through the transparent surface 203, so that the power generation cell panel 104 generates electricity. When part of the light irradiated by the transparent surface 203 is irradiated to the substrate 201 on the glass film 2 102, it is reflected by the reflective surface 1 204 on the substrate 201 to the EVA film 103, and passes through the EVA film 103 to irradiate the reflective surface 2 8 of the silicone plate 7, and is reflected by the reflective surface 2 8 to irradiate the power generation cell panel 104, thereby improving the light utilization rate of the gap groove 105 between two adjacent power generation cell panels 104.

[0027] Refer to the instruction manual Figure 1-5 The top surface of the EVA film 103 and the top surface of the glass film 102 are both hot-pressed to form a groove 3, and the two substrates 201 are fixedly bonded inside the two grooves 3. The groove 3 is provided to facilitate the rapid installation of the substrate 201;

[0028] The top surface of the EVA film 103 and the top surface of the second glass film 102 are both hot-pressed to form two grooves 24, which are distributed on both sides of the groove 13. Multiple power generation panels 104 are respectively fixed inside the two grooves 24 on the second glass film 102 for quick installation of the power generation panels 104;

[0029] A wire management hole 15 is provided at the front center of the substrate 201 in the groove 24 on the glass film 2 102. Wire management holes 26 are provided on both sides of the wire management hole 15. The wire management holes 26 are connected to the groove 24 and are used to place the wiring of the power generation battery panel 104.

[0030] The two grooves 2 4 at the bottom of the EVA film 103 are fixedly bonded with a silicone plate 7, and the cross-section of the silicone plate 7 is set to be wavy. With the help of the silicone plate 7, the impact resistance of the glass film 101 can be improved;

[0031] The outer wall surfaces at the bottom of the two silicone plates 7 are both reflective surfaces 2 8. Each reflective surface 1 204 and each reflective surface 2 8 are coated with an aluminum coating layer. Aluminum coating is a highly reflective material and can therefore improve the reflective performance of reflective surface 1 204 and reflective surface 2 8.

[0032] By setting a silicone plate 7 inside the groove 2 4 on the EVA film 103, the silicone plate 7 is made of a soft material. When the glass film 101 is pressed, the wavy silicone plate 7 can act as a buffer, thereby improving the impact resistance of the entire splitting structure film. A layer of aluminum paint is applied to the surface of the reflective surface 1 204 and the reflective surface 2 8. The aluminum paint layer is a highly reflective material, which can greatly improve the reflective performance of the reflective surface 1 204 and the reflective surface 2 8.

[0033] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
