Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making creative efforts shall fall within the protection scope of the present application.
Unless otherwise specifically noted, the terms used herein are to be understood as meaning as commonly used in the art. Accordingly, 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. If there is a conflict, the present specification will control.
Unless otherwise specifically stated, various raw materials, reagents, instruments, equipment and the like used in the present application are commercially available or can be prepared by an existing method.
The existing photovoltaic module with noctilucence has the technical problems that patterns on a photovoltaic cell panel are invisible at night and the energy utilization efficiency of the photovoltaic cell panel is low.
In order to solve the technical problems, the general idea of the technical scheme provided by the embodiment of the application is as follows:
in a first aspect, an embodiment of the present application provides a photovoltaic module with noctilucence, including: a photovoltaic cell panel and a color layer disposed on the photovoltaic cell panel,
the photovoltaic cell panel comprises a cell panel frame, a back panel, a photovoltaic cell and a transparent front panel, wherein the back panel, the photovoltaic cell and the transparent front panel are sequentially stacked in the cell panel frame;
the color layer includes a pigment and a phosphorescent material that absorbs ultraviolet rays and emits visible light.
The panel frame is used to hold other plate-like members of the photovoltaic panel, including a back plate, photovoltaic cells, and a transparent front plate, as will be appreciated by those skilled in the art. The material of the cell plate frame can adopt the conventional material in the field, such as a high polymer material and a metal material.
It will be understood by those skilled in the art that the backsheet is a product commercialized in the art. The back sheet is mainly used for protecting the photovoltaic cell and providing support for the photovoltaic cell.
It will be understood by those skilled in the art that the transparent front plate is a product commercialized in the art, and the transparent front plate commonly used in the art is made of ultra-white glass. The transparent front plate can also be made of transparent polymers.
As will be appreciated by those skilled in the art, the junction box is used to output the photocurrent generated by the photovoltaic cell.
As will be understood by those skilled in the art, pigment refers to a substance that can be applied and take on color and hue. In practical applications, UV light curable inks are often used as pigments.
As will be appreciated by those skilled in the art, the color layer may present a picture in the sun to improve the aesthetic appearance of the photovoltaic panel. Since the phosphorescent material can emit visible light again at night after absorbing sunlight in the daytime, the photovoltaic cell panel can also present a picture at a period of time at night or at the whole night.
As will be understood by those skilled in the art, phosphorescent material refers to a material having phosphorescence, and phosphorescence refers to the fact that, after absorbing incident light with a short wavelength, the phosphorescent material converts a part of the absorbed energy into internal energy directly or indirectly, and emits the other part of the absorbed energy in the form of emergent light with a long wavelength. Electrons of the phosphorescent material jump to an excited state after absorbing incident light with short wavelength, and are excited and radiate emergent light along with retreat, and the retreat excitation process is very slow because the retreat excitation process is forbidden by transition selection rules of quantum mechanics. Therefore, the phosphorescent material can emit phosphorescence after absorbing sunlight in the daytime, and the phosphorescence can continue to night to show noctilucence.
As will be appreciated by those skilled in the art, existing commercial photovoltaic panels typically absorb visible light to convert the light energy into electrical energy, and the wavelength range that can be absorbed is typically 360-760nm. The wavelength range of the ultraviolet light is defined as 200-400nm, which means that commercial photovoltaic panels cannot absorb most of the ultraviolet light. And the phosphor material in this application can absorb the ultraviolet ray back radiation visible light, can partly transmit the energy of ultraviolet ray for photovoltaic cell board with the form of visible light, helps improving photovoltaic cell board's generated power.
In the application, the pigment and the phosphorescent material can be mixed with each other, or can form two layers of different materials respectively, or can be distributed in different areas on the photovoltaic circuit board to jointly form a pattern.
It should be noted that the pigment layer generally includes a white pigment layer and a color pigment layer, and the white pigment layer serves as a substrate of the color pigment layer. The photovoltaic panel itself is mainly black or blue, and if colored pigments are added directly, the colors are not obvious, so that two pigment layers are often arranged in the field.
The phosphorescent material is arranged on the photovoltaic cell panel, so that colors on the photovoltaic cell panel can be visible at night; simultaneously phosphor material in this application can absorb the ultraviolet ray and change into visible light, can increase photovoltaic cell board's generated power.
In some embodiments of the present application, the phosphorescent material is a rare earth luminescent material.
As can be understood by those skilled in the art, most of the rare earth elements have 4f electrons capable of absorbing ultraviolet rays and radiating visible light, and common rare earth compounds can be used as rare earth noctilucent materials. In practical application, the rare earth luminescent material can be formed by rare earth luminescent paint. The rare earth luminous paint is a known product, and generally comprises two kinds of rare earth aluminate and rare earth silicate.
In some embodiments of the present application, the pigment forms a pigment layer on the photovoltaic panel and the phosphorescent material forms a phosphorescent layer on the photovoltaic panel.
It will be appreciated by those skilled in the art that forming the pigment and phosphorescent material into the pigment layer and the luminescent layer, respectively, is easy, simple and fast to process.
In some embodiments of the present application, the thickness of the luminescent layer is 10-20 μm.
In this application, the luminescent layer and the pigment layer may block a portion of the visible light that is incident on the photovoltaic panel. When the thickness of the noctilucent layer is too thick, more visible light can be shielded to a certain extent, and the power generation power of the photovoltaic cell panel is further influenced. When the thickness of the noctilucent layer is thin to a certain degree, the shielding of visible light is little, the power generation power of the photovoltaic cell panel is basically not influenced, the conversion efficiency of ultraviolet rays is correspondingly reduced, the improvement of the power generation power of the photovoltaic cell panel is adversely affected, and meanwhile, the noctilucent layer is too thin, so that noctilucent is too weak, and the color development effect at night is poor.
In some embodiments of the present application, the luminescent layer is disposed on the photovoltaic panel in a patterned manner.
By patterned as described herein, it is meant that the luminescent layer does not cover the entire photovoltaic panel, but partially covers and forms a pattern. The purpose of patterning is to illuminate a specific area at night and present a specific pattern, and to reduce the amount of material used for the noctilucent layer and to reduce the cost.
In some embodiments of the present application, the luminescent layer and the pigment layer are stacked, and the luminescent layer is located on one side of the color layer close to the photovoltaic panel.
As can be understood by those skilled in the art, the noctilucent layer is positioned on one side of the color layer close to the photovoltaic cell panel, so that the noctilucent layer can be prevented from being directly irradiated by sunlight, and the phenomenon that the surface of the noctilucent layer is cracked due to too fast temperature change is avoided.
In a second aspect, based on a general inventive concept, embodiments of the present application further provide a method for manufacturing a photovoltaic module with noctilucence, which can be used for manufacturing the photovoltaic module with noctilucence according to any embodiment of the first aspect, and the method for manufacturing the photovoltaic module with noctilucence includes the following steps:
the embodiment of the application provides a preparation method of a photovoltaic module with noctilucence, which can be used for preparing the photovoltaic module with noctilucence described in any one of the embodiments of the first aspect, and the preparation method of the photovoltaic module with noctilucence comprises the following steps:
s1: providing a photovoltaic cell panel;
s2: a pigment and a phosphorescent material which can absorb ultraviolet rays and emit visible light are used as raw materials, and a color layer is formed on the photovoltaic cell panel.

In some embodiments of the present application, the phosphorescent material is a rare earth luminescent material.
As will be understood by those skilled in the art, most rare earth elements have 4f electrons capable of absorbing ultraviolet rays and radiating visible light, and common rare earth compounds can be used as rare earth noctilucent materials. In practical application, the rare earth luminescent material can be formed by rare earth luminescent paint. The rare earth luminous paint is a known product, and generally comprises two kinds of rare earth aluminate and rare earth silicate.

s222: and forming a noctilucent layer on the pigment layer and/or the photovoltaic cell panel by taking the phosphorescent material as a material.
As will be understood by those skilled in the art, in step S211, the noctilucent layer may cover the entire photovoltaic cell panel, or may partially cover the photovoltaic cell panel and form a pattern. Correspondingly, in step S212, when the noctilucent layer covers the whole photovoltaic cell panel, the pigment layer is formed on the noctilucent layer, and the pigment layer may also cover the noctilucent layer wholly or partially; when the luminescent layer partially covers the photovoltaic panel, the pigment layer may cover the luminescent layer and the exposed areas of the photovoltaic panel not covered by the luminescent layer in whole or in part, or cover the luminescent layer only in whole or in part, or cover the exposed areas of the photovoltaic panel not covered by the luminescent layer only in whole or in part.
Similarly, in step S221, the pigment layer may cover the entire photovoltaic cell panel, or may partially cover the photovoltaic cell panel and form a pattern. Correspondingly, in step S212, when the pigment layer covers the whole photovoltaic cell panel, the noctilucent layer is formed on the noctilucent layer, and the noctilucent layer may also cover the pigment layer wholly or partially; when the pigment layer partially covers the photovoltaic cell panel, the noctilucent layer may cover the pigment layer and the exposed portion of the photovoltaic cell panel not covered by the pigment layer, or cover the pigment layer only, or cover the exposed portion of the photovoltaic cell panel not covered by the pigment layer, either entirely or partially.
It will be appreciated by those skilled in the art that the method of forming the luminescent layer may be any method known in the art including, but not limited to, spraying, brushing.
As will be understood by those skilled in the art, the formation of the noctilucent layer by using the phosphorescent material as a material refers to forming the noctilucent layer by disposing a raw material containing the phosphorescent material, which is easy to form a film, on the photovoltaic cell panel or the pigment layer, and the raw material containing the phosphorescent material, which is easy to form a film, includes, but is not limited to, a phosphorescent material solution, a phosphorescent material suspension, and a phosphorescent material slurry.
