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.
The existing photovoltaic cell panel is provided with patterns covered by partial areas, so that visible light irradiated to the photovoltaic cell panel from the areas covered by the patterns is reduced, and further, a hot spot effect is easily generated.
The technical scheme provided by the embodiment of the application aims to solve the technical problems, and the overall thought is as follows:
in a first aspect, embodiments of the present application provide a partially covered patterned photovoltaic module comprising a photovoltaic panel, a color layer, and a refractive layer,
referring to fig. 1, the photovoltaic cell panel includes a panel frame 1, a back plate 2, a photovoltaic cell 3 and a glass front plate 4 sequentially stacked in the panel frame 1, wherein both sides of the photovoltaic cell 3 are provided with adhesive films 5 and are respectively adhered to the back plate 2 and the glass front plate 4 through the adhesive films 5, and a junction box electrically connected with the photovoltaic cell 3 is arranged on the back plate 2;
the surface of the glass front plate 4 comprises a pattern area and an exposed area, and the color layer is arranged on the pattern area;
the refraction layer is arranged at the joint of the exposed area and the pattern area, and the refraction layer is formed by a light diffusion agent.
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.
It will be appreciated by those skilled in the art that the adhesive film primarily serves as an adhesive for bonding the back sheet and transparent front sheet to the photovoltaic cells. The adhesive film is a commercial product in the field, and the adhesive film commonly used in the field is EVA (ethylene-vinyl acetate copolymer) material.
As will be appreciated by those skilled in the art, the junction box is used to output photocurrent generated by the photovoltaic cell.
As will be appreciated by those skilled in the art, the hot spot effect refers to: under certain conditions, part of cells in the photovoltaic system are shielded by other surrounding objects, so that local shadows are caused, and the shielded parts are caused to generate heat. The conditions herein may be, for example, shadows of leaves, bird droppings, and dark color patches as described herein. The specific principle is that the photoelectric voltage of the part with less illumination is low, the photoelectric voltage of the part with more illumination is high, and current flows from the part with high photoelectric voltage to the part with low photoelectric voltage, so that electric heating is caused.
According to the method, the refraction layer is arranged at the joint of the exposed area and the pattern area and is formed by the light diffusion agent, so that the propagation direction of visible light can be changed through the refraction layer, part of the visible light can be irradiated to the part covered by the pattern area, the photovoltaic voltage of the photovoltaic cell panel in the pattern area is increased, the internal current of the photovoltaic cell panel is reduced, and the hot spot effect can be relieved.
In some embodiments of the present application, the light diffusing agent is a silicone light diffusing agent.
It is understood by those skilled in the art that the organosilicon light diffusing agent is a polymer transparent microsphere with a three-dimensional structure connected by a silicon oxygen bond, is easy to form a film, and is oxidation-resistant and ultraviolet-resistant. The light can deflect in the propagation direction when passing through the transparent microspheres, and the refraction layer formed by the transparent microspheres can deflect the light in the light beam in multiple directions, so that the irradiation area of the light beam after passing through the refraction layer is increased, and the light beam can be irradiated to places which cannot be irradiated along the original linear light path.
In some embodiments of the present application, the particle size of the diffuser particles in the silicone light diffuser is 3-5 μm.
As will be appreciated by those skilled in the art, the particle size of the diffuser is small enough that the film formation will be relatively uniform. However, if the particle size of the diffusing agent is too small, the arrangement is too compact, the optical performance is more similar to that of a continuous film, and the diffusing ability is weakened. The particle size distribution of the dispersing agent is narrower, the change of the light path is simpler, and the light energy is not refracted, reflected and lost for many times due to uneven particle size distribution.
In some embodiments of the present application, the color layer includes a white layer disposed on the glass front plate and a color layer disposed on the white layer.
It can be understood by those skilled in the art that the photovoltaic panel itself is mainly black or blue, in order to make the color pattern more obvious, a white layer is preset on the photovoltaic panel, and then the white layer is patterned with color pigment, so that the pattern has a white background and color development is more obvious.
In some embodiments of the present application, the material of the white layer is a UV light curable ink; and/or the number of the groups of groups,
the material of the color layer is UV light curing ink.
As will be understood by those skilled in the art, UV curable inks refer to inks that are formed into films and dried by polymerizing monomers in an ink vehicle into a polymer under ultraviolet radiation using ultraviolet light of different wavelengths and energies. The UV light curing ink has the characteristics of strong adhesion, smooth surface, quick curing film formation, simple use and the like. The UV light curable ink may be printed by UV printing, screen printing, or the like to form a white layer or a color layer.
In some embodiments of the present application, the white layer has a thickness of 10-20 μm; and/or the number of the groups of groups,
the thickness of the color layer is 10-20 μm.
Those skilled in the art will appreciate that the white layer may block a portion of visible light, which affects the working efficiency of the photovoltaic panel, and thus the white layer is not necessarily too thick. The white layer serves as a background layer for the color layer, and if the thickness is too thin, the background color is not strong enough.
Those skilled in the art will appreciate that the color layer may block a portion of visible light, which affects the working efficiency of the photovoltaic panel, and thus the color layer should not be too thick. If the color layer is too thin, the color development is not noticeable.
In some embodiments of the present application, the refractive layer has a thickness of 5-10 μm.
It will be appreciated by those skilled in the art that the refractive layer itself will consume a portion of the light and is therefore not preferred to be too thick. If the refractive layer is too thin, the diffusion effect of light is not obvious, and the hot spot effect is not sufficiently significantly suppressed.
In a second aspect, embodiments of the present application provide a building on which the photovoltaic module of the partial coverage pattern of any of the embodiments of the first aspect is disposed. The building may be any form of building including, but not limited to, a building, bridge, greening facility, factory building, etc. The building is implemented based on the embodiment of the first aspect, and the specific implementation manner of the building can refer to the embodiment of the first aspect, and since the building adopts part or all of the technical solutions of the foregoing embodiments, at least all of the beneficial effects brought by the technical solutions of the foregoing embodiments are not described in detail herein.

Related experiment and effect data:
the hot spot effect of the fluorescent photovoltaic modules in examples 1 to 5 and comparative examples was detected, specifically, the temperatures of the center point of the exposed area and the center point of the pattern area were detected by a temperature measuring gun, and the average value was calculated, and then the temperature difference between the temperature of the center point of the exposed area and the temperature of the center point of the pattern area was calculated.
The test results are shown in the following table:
the temperature difference in the above table refers to the temperature difference between the temperature at the center point of the bare area and the temperature at the center point of the pattern area.
As can be seen from the above table, in examples 1 to 5, the temperature difference between the temperature of the center point of the bare area and the temperature of the center point of the pattern area was significantly lower than that of the comparative example, which demonstrates that examples 1 to 5 make the light distribution more uniform by providing the refractive layer, and the hot spot effect was reduced.
