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, 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 field currently lacks a full-flow manufacturing method of a color photovoltaic module.
In order to solve the technical problems, the general idea of the technical scheme provided by the embodiment of the application is as follows:
an embodiment of the present application provides a method for manufacturing a color photovoltaic module, please refer to fig. 1, where the method for manufacturing a color photovoltaic module includes the following steps:
s1: providing a front plate, and cleaning the surface of the front plate;
s2: carrying out surface treatment including plasma treatment on the surface of the cleaned front plate;
s3: printing a pigment layer on the surface of the front plate after the plasma treatment by using a UV printer to obtain a color front plate;
s4: providing a first adhesive film, a second adhesive film, a photovoltaic cell panel and a back panel, and laminating according to the sequence of the colored front panel, the first adhesive film, the photovoltaic cell panel, the second adhesive film and the back panel to obtain a colored photovoltaic panel;
s5: and (4) loading the color photovoltaic panel into an installation frame, and installing a junction box to obtain the color photovoltaic module.
As will be appreciated by those skilled in the art, the front plate is typically the light-receiving side of a color photovoltaic module, and is typically made of glass or ETFE (ethylene-tetrafluoroethylene copolymer).
The surface treatment of the front plate is intended to improve the surface properties of the front plate and to enhance the adhesion of the front plate surface to the pigment layer. The surface treatment generally comprises a plasma treatment. Plasma treatment refers to bombarding the surface of a material with plasma to change the roughness of the surface of the material. The surface treatment of the present application is not limited to plasma treatment, but may also include other conventional surface treatment means in the art, such as chemical etching, chemical modification, and the like. In practical applications, the goal of the surface treatment is to improve the surface tension of the front panel surface to greater than 40N/cm.
The pigment layer is printed by a UV printer, and thus the material is a UV light curable ink, as will be appreciated by those skilled in the art.
As can be understood by those skilled in the art, the colored front plate, the first adhesive film, the photovoltaic cell panel, the second adhesive film and the back plate are arranged in the conventional arrangement sequence of the structures of the photovoltaic module.
It will be understood by those skilled in the art that the first adhesive film and the second adhesive film are conventional in the art and are used to bond other structures together. The materials of the first adhesive film and the second adhesive film can be the same or different.
The front plate is cleaned, subjected to surface treatment and the like, so that the pigment layer can be firmly attached to the surface of the front plate; the pigment layer is printed on the front plate in advance before assembly, so that operation is convenient, and pigment cannot be printed on the mounting frame by mistake. Therefore, the manufacturing method of the colorful photovoltaic module can stably and reliably manufacture the colorful photovoltaic module.
In some embodiments of the present application, the cleaning of the front plate surface is performed by blowing high pressure air with a wind speed of not less than 1.5 m/s.
In some embodiments of the present application, the high pressure wind has a purge rate of 4-6m 2 /min。
In practical applications, the cleaning targets are: the maximum value of the dust falling particles on the surface of the front plate is 10 particles/m 2 。
In some embodiments of the present application, the surface treatment further comprises applying a glass coating solution to the surface of the front plate.
As will be understood by those skilled in the art, a glass coating solution refers to a coating solution that increases the surface tension of glass, and is generally a resin as a major component. As an example, a glass coating liquid produced by Green spring industries, ltd, dongguan may be used.
In practical applications, it sometimes happens that the surface tension of the front plate surface after plasma modification cannot reach more than 40N/cm. This is often the case when the front sheet material is glass. In this case, therefore, the glass coating liquid is applied to perform surface treatment, which further increases the surface tension of the front plate surface.
In some embodiments of the present application, the pigment layer has a thickness of 0.01 to 0.03mm.
In some embodiments of the present application, the pigment layer includes a white pigment layer formed of white UV ink and a color pigment layer formed of color UV ink disposed on the white pigment layer.
Because the color of the photovoltaic cell panel is black or dark blue, the white pigment layer is arranged to be used as a background layer of the color pigment layer, so that the color of the color pigment layer is more obvious.
In some embodiments of the present application, the white UV ink has a light blocking ratio of no more than 45% at a thickness of 0.02 mm; and/or the presence of a gas in the gas,
the light shading rate of the colored UV ink is not more than 20% when the thickness of the colored UV ink is 0.015 mm.
The shading rate affects the power generation power of the photovoltaic module, and is generally not too high.
In some embodiments of the present application, the material of the first adhesive film is selected from at least one of EVA (ethylene-vinyl acetate copolymer), POE (polyolefin elastomer), PVB (polyvinyl butyral resin); and/or the presence of a gas in the gas,
the material of the second adhesive film is at least one of EVA, POE and PVB.
In some embodiments of the present application, the first adhesive film is made of EVA, and the second adhesive film is made of any one of PVB and POE.
The front plate only needs to provide support for the pigment layer and does not need to have electrical performance, so that the material of the first adhesive film is preferably EVA; the back plate needs to have electrical performance and needs to realize functions of power connection and the like, so the material of the second adhesive film is preferably any one of PVB or POE.
In some embodiments of the present application, the method of manufacturing a color photovoltaic module further comprises the steps of:
carrying out hot spot effect detection on the color photovoltaic module;
and thinning or removing the pigment in the area where the hot spot effect occurs.
As will be understood by those skilled in the art, the hot spot effect refers to: partial cells in the photovoltaic system are occluded by other objects around, causing local shadows and causing the occluded parts to heat up. The conditions here may be, for example, the shade of the leaves, bird droppings, and dark color patches described in this application. The specific principle is that the light voltage of a part which is less illuminated is low, the light voltage of a part which is more illuminated is high, and the current flows from the part with high light voltage to the part with low light voltage, so that the electric heating is caused.
The pigment in the area with the hot spot effect is thinned or removed, so that the transmittance of the area can be increased, and the hot spot effect is relieved.
The thinning or removal process described herein generally refers to ablation of the pigment layer by a laser.
Various embodiments of the present application may exist in a range of forms; it is to be understood that the description in range format is merely for convenience and brevity and should not be construed as an inflexible limitation on the scope of the application; accordingly, the described range descriptions should be considered to have specifically disclosed all the possible sub-ranges as well as individual numerical values within that range. For example, it is contemplated that the description of a range from 1 to 6 has specifically disclosed sub-ranges, such as from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 6, from 3 to 6, etc., as well as single numbers within the stated range, such as 1, 2, 3, 4, 5, and 6, as applicable regardless of the range. In addition, whenever a numerical range is indicated herein, it is meant to include any number (fractional or integer) recited within the range so indicated.
In this application, where the context requires no explicit explanation, the use of directional words such as "upper" and "lower" in particular refers to the direction of the drawing in the figures. In addition, in the description of the present specification, the terms "include", "includes" and the like mean "including but not limited to".

Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of another like element in a process, method, article, or apparatus that comprises the element. In this document, relational terms such as "first" and "second," and the like, may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Herein, "and/or" describes an association relationship of associated objects, meaning that there may be three relationships, e.g., a and/or B, may mean: a is present alone, A and B are present simultaneously, and B is present alone. For the association relationship of more than three associated objects described by "and/or", it means that any one of the three associated objects may exist alone, or any at least two of the three associated objects may exist simultaneously, for example, for a, and/or B, and/or C, it may mean that any one of A, B, C exists alone, or any two of the three associated objects exist simultaneously, or three of the three associated objects exist simultaneously. As used herein, "at least one" means one or more, "a plurality" means two or more. "at least one," "at least one of the following," or similar expressions, refer to any combination of these items, including any combination of the singular or plural items. For example, "at least one (a), b, or c", or "at least one (a), b, and c", may each represent: a, b, c, a-b (i.e., a and b), a-c, b-c, or a-b-c, wherein a, b, and c may be single or plural, respectively.
The above description is merely exemplary of the present application and is presented to enable those skilled in the art to understand and practice the present application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the application.
