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 has the technical problems that the visible light irradiating on the photovoltaic cell panel covering the low-light-transmission pigment part is less, and the hot spot effect is generated.
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, the embodiments of the present application provide a color photovoltaic module with improved light transmittance, which includes a photovoltaic cell panel and a color layer,
the photovoltaic cell panel comprises a cell panel frame, a back panel, a photovoltaic cell and a glass front panel, wherein the back panel, the photovoltaic cell and the glass front panel are sequentially stacked in the cell panel frame;
the color layer includes a white layer disposed on the glass front plate and a color layer disposed on the white layer, and referring to fig. 1, the white layer 1 is formed of a plurality of white color lines which are parallel to each other and arranged in a first direction.
The panel frame is used to hold other panel-like members of the photovoltaic panel, including a back panel, photovoltaic cells, and a transparent front panel, 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 molecular 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 adhesive film serves primarily as a bonding means for bonding the back sheet and the transparent front sheet to the photovoltaic cell. The adhesive film is a commercial product in the field, and the adhesive film commonly used in the field is made of an EVA (ethylene-vinyl acetate copolymer) material.
As will be appreciated by those skilled in the art, the junction box is used to output the photocurrent generated by the photovoltaic cell.
According to the photovoltaic cell panel, the white layer is arranged into the plurality of white pigment lines which are parallel to each other, and the visible light can be directly emitted into the photovoltaic cell panel through gaps among the pigment lines without passing through the white pigment layer, so that more visible light can be transmitted, and the blocking of the white layer to the visible light is reduced compared with the conventional arrangement mode of the complete continuous white layer in the field;
in addition, if the compactness of the white pigment lines is proper, the degree that gaps among the white pigment lines are difficult to distinguish by naked eyes can be achieved, and the attractive effect is hardly influenced; or may be made to be visible to the naked eye to create a particular pattern effect.
In some embodiments of the present application, referring to fig. 2, the color layer 2 is formed by a plurality of color pigment lines parallel to each other and arranged along a second direction, and the first direction and the second direction have a predetermined included angle therebetween.
It will be appreciated by those skilled in the art that the color layer also provides a barrier to visible light, and that the provision of multiple parallel lines of color pigment can also provide increased transmission of visible light.
In addition, if the compactness of the color pigment lines is proper, the degree that gaps among the color pigment lines are difficult to distinguish by naked eyes can be achieved, and the attractive effect is hardly influenced; or it may be made to the extent that the lines are visibly apparent to the naked eye to create a particular pattern effect.
In some embodiments of the present application, the width of the white pigment line is 2-20 μm; and/or the presence of a gas in the gas,
the spacing between the white pigment lines is 2-20 μm.
Those skilled in the art will appreciate that the wider the width of the white color lines, the greater the barrier to light, but the better the continuity of the white layer, the spacing can be relaxed appropriately; the narrower the width of the white color line, the smaller the light blocking, but the pitch is also narrowed in order to allow the naked eye to observe a continuous pattern.
Since the white pigment lines themselves have a certain thickness, visible light is not always incident on the photovoltaic panel perpendicularly, but is often incident on the photovoltaic panel obliquely, passing through the interval between the white pigment lines, and being incident on the photovoltaic panel. When the interval is too narrow, the oblique light hardly passes through the interval between the white color lines.
Combining the above factors, a width of the white color lines of 2-20 μm and a spacing between the white color lines of 2-20 μm are suitable parameters to obtain in practice.

Combining the above factors, the width of the color pigment lines of 2-20 μm and the spacing between the color pigment lines of 2-20 μm are the more suitable parameters to obtain in practice.
In some embodiments of the present application, the predetermined included angle is 90 °.

In some embodiments of the present application, the material of the white layer is white UV light curable ink, and the material of the color layer is colored UV light curable ink.
As will be understood by those skilled in the art, UV light curable ink refers to ink that is formed into a film and dried by polymerizing monomers in an ink vehicle into polymers under UV radiation at various wavelengths and energies. The UV light-cured ink has the characteristics of strong adhesion, smooth surface, quick curing and film forming, simple use and the like. The UV light-curable ink can be printed by UV printing, screen printing or the like to form a white layer or a colored layer.
In some embodiments of the present application, the width of each of the white color lines and the color lines is 10 μm, and the interval between the white color lines and the interval between the color lines are 10 μm.

The generated power of example 2 is significantly higher than that of examples 5-8, which shows that the width and spacing of the pigment lines adopted in example 2 are more appropriate, which is beneficial for increasing the incidence of visible light.
