All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present application based on the embodiments herein.
Unless specifically stated otherwise, the terms used herein should be understood as meaning as commonly used in the art. Thus, unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. In case of conflict, the present specification will control.
Unless specifically indicated otherwise, the various raw materials, reagents, instruments, equipment, and the like used in this application are commercially available or may be prepared by existing methods.
In the prior art, a white pigment layer is firstly arranged on a photovoltaic cell panel, and then a color pigment is arranged on the white pigment layer. However, the white pigment may reflect almost all visible light, which causes a part of the visible light to be blocked by the white pigment, resulting in the generated power of the photovoltaic panel to be affected.
The technical scheme provided by the embodiment of the application aims to solve the technical problems, and the overall thought is as follows:
referring to fig. 1 and 2, in a first aspect, an embodiment of the present application provides a photovoltaic module having a fluorescent layer 02, where the photovoltaic module having the fluorescent layer 02 includes:
referring to fig. 3, a photovoltaic cell panel 01 includes a panel frame 1, a back plate 2, a photovoltaic cell 3 and a transparent front plate 4 sequentially stacked in the panel frame 1, wherein two sides of the photovoltaic cell 3 are respectively provided with a glue film 5 and are respectively adhered to the back plate 2 and the transparent front plate 4 through the glue films 5, and a junction box electrically connected with the photovoltaic cell 3 is arranged on the back plate 2;
a fluorescent layer 02 arranged on the photovoltaic cell panel 01, wherein the fluorescent layer 02 comprises a fluorescent material, and the fluorescent layer 02 presents white under natural light;
a color layer 03 disposed on the fluorescent layer 02, wherein the color layer 03 is made of pigment. The pigment may be, for example, a UV light curable ink.
Those skilled in the art will appreciate that the panel frame is used to secure other panel-like members of the photovoltaic panel, including back sheets, photovoltaic cells, transparent front sheets. The material of the panel frame may be a conventional material in the art, such as a polymer material and a metal material.
Those skilled in the art will appreciate that the back sheet is a commercial product in the art. The back plate is mainly used for protecting the photovoltaic cell and providing support for the photovoltaic cell.
It will be appreciated by those skilled in the art that transparent front plates are commercially available in the art, and that transparent front plates commonly used in the art are made of ultra-white glass. Transparent polymers can also be selected as the material of the transparent front plate.
As will be appreciated by those skilled in the art, the junction box is used to output photocurrent generated by the photovoltaic cell.
It will be appreciated by those skilled in the art that the color layer 03 may be pictured in sunlight to improve the aesthetic effect of the photovoltaic panel 01.
As will be understood by those skilled in the art, fluorescent materials refer to materials that exhibit a fluorescence phenomenon, where fluorescence refers to absorption of incident light at a short wavelength by a fluorescent material, and then the absorption of some of the energy is directly or indirectly converted into internal energy, and the other is emitted as outgoing light at a long wavelength. Wherein the emergent light is visible light, and the emergent light of the visible light is shown to emit fluorescence. Electrons of the fluorescent material transition to an excited state after absorbing incident light of a short wavelength, and then de-excite and radiate outgoing light. The time interval from the absorption of photons to the de-excitation of released photons is very short, generally not higher than 20ms, and macroscopically shows that the incident light is once disappeared, and the fluorescence phenomenon is also disappeared.
It will be appreciated by those skilled in the art that the material of the fluorescent layer 02 may be all fluorescent materials, or some auxiliary agents, color-adjusting pigments, etc. may be added thereto.
The fluorescent layer 02 is used for replacing the white pigment layer, and the fluorescent layer 02 adopted by the application is white under natural light, so that the same effect as that of the white pigment layer can be achieved, and the color development of the color layer 03 is not affected; when part of the short-wave light in the natural light irradiates the fluorescent layer 02, the part of the short-wave light can be absorbed by the fluorescent layer 02 instead of being directly reflected, the fluorescent layer 02 absorbs the short-wave light and emits visible light, and part of the visible light can irradiate the photovoltaic cell panel 01 to increase the power generation of the photovoltaic cell panel 01.
In some embodiments of the present application, the thickness of the fluorescent layer 02 is 10-20 μm.
As will be appreciated by those skilled in the art, if the thickness of the fluorescent layer 02 is too thin, the white color is not strong enough, which will result in color distortion of the color layer 03 to some extent; when the thickness of the fluorescent layer 02 is too thick, the fluorescent layer 02 is white, so that visible light is reflected, the visible light is blocked, natural light and visible light emitted by the fluorescent layer 02 are not easy to irradiate on the photovoltaic cell panel 01, and the power generation power of the photovoltaic cell panel 01 is affected.
In some embodiments of the present application, the thickness of the color layer 03 is 10-25 μm.
As will be appreciated by those skilled in the art, the color layer 03 is too thin and the color is not vivid; too thick color layer 03 reflects too much visible light, affecting the power generated by photovoltaic panel 01.
In some embodiments of the present application, the photovoltaic module having the fluorescent layer 02 further comprises an excitation light source for emitting excitation light for exciting the fluorescent layer 02 to emit light.
It will be appreciated by those skilled in the art that the excitation light source is turned on mainly at night, and the color layer 03 is visible at night after excitation of fluorescence. The excitation light is short wave light, and the excitation light can be at least one of ultraviolet light, purple light and blue light.
In some embodiments of the present application, the excitation light is blue light, and the material of the fluorescent layer 02 includes a fluorescent material that absorbs blue light and releases yellow light.
The prior art has a scheme that ultraviolet light is used for exciting the fluorescent material to emit light so that the fluorescent material is visible at night. However, in particular, in the present application, since the color layer 03 is further provided on the fluorescent material, there is a problem that color fidelity is also required. The application takes blue light as excitation light, the fluorescent layer 02 absorbs the blue light and emits yellow light, and the blue light and the yellow light can be combined into white light under a proper light intensity ratio. The color layer 03 and the phosphor layer 02 reflect a portion of the blue light on the one hand and yellow light emitted by the phosphor layer 02 is transmitted out of the color layer 03 on the other hand, and the blue light and the yellow light are combined to white light on the color layer 03, so that the color layer 03 is visible at night and the color is not distorted.
In some embodiments of the present application, the photovoltaic module with the fluorescent layer 02 further includes a transparent light guiding layer 04, and the excitation light source is disposed at a side edge of the transparent light guiding layer 04;
referring to fig. 1, the transparent light guiding layer 04 is disposed on the color layer 03,
or alternatively, the process may be performed,
referring to fig. 2, the transparent light guiding layer 04 is disposed between the fluorescent layer 02 and the photovoltaic panel 01.
As will be appreciated by those skilled in the art, the excitation light source is disposed at the side of the transparent light guide layer 04, so that the excitation light source uniformly irradiates the color layer 03 and the fluorescent layer 02 along with the transparent light guide layer 04.
As can be appreciated by those skilled in the art, when the transparent light guiding layer 04 is disposed on the color layer 03, when the excitation light is blue light, the fluorescent layer 02 emits yellow light, and since the blue light is brighter at the position close to the excitation light source, a blue-to-white gradient color light ring is formed at the edge of the transparent light guiding layer 04, so that a good visual effect is achieved. When the transparent light guiding layer 04 is disposed between the fluorescent layer 02 and the photovoltaic panel 01, the gradual color change is not obvious due to the coverage of the color layer 03 and the fluorescent layer 02.
It will be appreciated by those skilled in the art that the excitation light source may be a plurality of beads, such as LED beads; or may be a light strip. The excitation light source can be limited on the outer side of the transparent light guide layer 04 in a conventional manner in the art, and can also be embedded on the side edge of the transparent light guide layer 04. The embedding method may be, for example, etching a groove on the side edge of the transparent light guiding layer 04 by laser, and then embedding the excitation light source therein.
In some embodiments of the present application, the material of the transparent light guiding layer 04 is glass or plexiglass.
