Description
Technical Field
The utility model relates to a photovoltaic module makes technical field, especially relates to a photovoltaic solder strip and photovoltaic module.
Background
Because the output voltage of a single solar cell is low, a plurality of solar cells are generally required to be connected in series and in parallel and then are tightly packaged into a photovoltaic module.
In the application process of the photovoltaic module, if a solar cell sheet forming the photovoltaic module is shielded by a foreign object or due to defects of the solar cell sheet, a hot spot effect occurs on the solar cell sheet. The temperature of the solar cell sheet where the hot spot effect occurs increases. If the solar cell with the hot spot effect cannot be found out in time and maintained or replaced, the whole photovoltaic module is possibly damaged.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a photovoltaic solder strip and photovoltaic module for at the in-process that photovoltaic module used, the solar wafer of the hot spot effect is produced in timely accurate definite generation, prevents to damage whole photovoltaic module.
In a first aspect, the utility model provides a photovoltaic solder strip. The photovoltaic solder strip comprises at least one welding section welded with a solar cell piece, and the non-welding surface of each welding section is provided with a reversible thermochromic layer. When the temperature of the solar cell reaches a specific temperature, the reversible thermochromic layer is changed from the first color to the second color.
Under the condition of adopting the technical scheme, the photovoltaic welding strip comprises at least one welding section welded with the solar cell piece, and a non-welding surface of each welding section is provided with a reversible thermochromic layer. When the solar cell generates a hot spot effect, the temperature of the solar cell is increased. Because the welding section is made of metal materials and has good heat conduction performance, the welding section can rapidly and accurately transfer the temperature generated by the solar cell to the reversible heating layer. When the temperature of the solar cell rises to a specific temperature, the reversible heating layer can be changed from the first color to the second color.
The welding sections provided with the reversible heat layers are welded on each solar cell piece, so that when the color of the reversible heat layers on the non-welding surface of any welding section is changed, the generation efficiency of the photovoltaic module cannot be reduced due to reduction of the transmittance of sunlight, the specific position of the solar cell piece generating the hot spot effect can be accurately determined, the solar cell piece generating the hot spot effect can be conveniently replaced or maintained in time, and the whole photovoltaic module is prevented from being damaged.
In one possible implementation, the reversible thermochromic layer has a color change temperature greater than or equal to 40 ℃ and less than or equal to 150 ℃.
When the solar cell has hot spot effect, the temperature of the solar cell can reach about 50 ℃ at the lowest, and can reach 150 ℃ at the highest. Therefore, the color change temperature range of the reversible thermochromic layer needs to be basically the same as the temperature range of the solar cell piece when the hot spot effect occurs.
In one possible implementation, the reversible thermochromic layer is an inorganic thermochromic material. The inorganic thermochromic material is made of a tetraiodomercuric acid metal compound.
The inorganic thermochromic material has more discoloration mechanisms, and one important discoloration mechanism is a crystal form transformation mechanism. When the inorganic thermochromic material is heated to a specific temperature, the inorganic thermochromic material is transformed from one crystal form to another crystal form, thereby transforming the inorganic thermochromic material from a first color to a second color. When the temperature returns to the room temperature, the crystal form of the inorganic thermochromic material is recovered, and the inorganic thermochromic material is changed into the first color from the second color. Most metalates of the tetraiodomercuric acid class have the above-mentioned mechanism of discoloration. In order to timely determine the solar cell sheet generating the hot spot effect, the temperature range of the color transition of the tetraiodomercuric acid metal compound needs to be basically the same as the temperature range of the solar cell sheet generating the hot spot effect. For example: cu2HgI4The red color is red under the normal temperature environment, the dark purple color is changed under the environment of 69.6 ℃, and the black color is changed under the environment of 70.6 ℃; ag2HgI4Can be reversibly changed from yellow to red under the environment of 45-50 ℃.
In one possible implementation, the reversible thermochromic layer is a metal organic complex temperature indicating material.
The material of the metal organic complex temperature indicating material is a metal copper organic complex temperature indicating material and/or a metal nickel organic complex temperature indicating material. The metal organic complex temperature indicating material comprises [ (C)2H5)2NH2]2CuCl4And/or [ (CH)3)2CHNH2]CuCl3. The main discoloration mechanism of metal-organic complexes is a change in structure or coordination number. For example: [ (C)2H5)2NH2]2CuCl4The color of the product changes from green to yellow under the environment of 43 ℃; [ (CH)3)2CHNH2]CuCl3The color turns from brown to orange under the environment of 52 ℃.
In one possible implementation, the reversible thermochromic layer is an organic thermochromic material. The organic thermochromic material is made of a spiro compound, a dianthrone compound, a Schiff base compound, a fluorescent compound or a triphenylmethane compound.
In one possible implementation, a reversible thermochromic layer is applied over the entire non-bonding surface. Or the reversible thermochromic layer is coated on the surface of the non-welding surface at intervals.
When the reversible thermochromic layer is coated on the surface of the whole non-welding surface, the specific position of the solar cell with the hot spot effect can be directly observed according to the color change condition of the reversible thermochromic layer under the condition that the solar cell generates the hot spot effect. When the reversible thermochromic layer is coated on the surface of the non-welding surface at intervals, not only can materials be saved, but also the specific position of the solar cell piece generating the hot spot effect can be observed more clearly and directly.
In one possible implementation, the thickness of the reversible thermochromic layer is D and the thickness of the weld segment is D, wherein,
the thickness of the reversible thermochromic layer needs to be limited in order not to affect the performance of the solar cell sheet. When the thickness of the reversible thermochromic layer is not more than one fifth of the thickness of the welding section, the effect of detecting the solar cell piece generating the hot spot effect can be achieved, and the performance of the solar cell piece cannot be influenced.
In a second aspect, the utility model also provides a photovoltaic module. The photovoltaic module comprises a plurality of solar cells, and two adjacent solar cells are electrically connected through the photovoltaic solder strip described in the first aspect.
The utility model discloses the beneficial effect of the photovoltaic module that the second aspect provided is the same with the beneficial effect of the photovoltaic solder strip that first aspect or any possible implementation of first aspect described, and the here is not repeated.

The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
When a solar cell shielded in a serial branch or a solar cell itself has a defect, the solar cell may be used as a load to consume energy generated by other normal solar cells. At this time, the solar cell generates heat, which is a hot spot effect.
In the related art, a method of arranging a transparent observation window above a junction box is disclosed, in which whether a hot spot effect is generated in a photovoltaic module is detected. In this way, a reversible thermochromic device needs to be provided on the surface of the inverse diode in the junction box. When the solar cell has a hot spot effect, the temperature of the inverse diode rises, so that the color of a reversible thermochromic device arranged on the surface of the inverse diode changes, and the abnormality of the photovoltaic module can be observed. However, with this method, the specific position of the solar cell that generates the hot spot effect cannot be accurately determined. Meanwhile, the reversible thermochromic device is arranged inside the junction box, so that the photovoltaic module is not beneficial to being observed on the front side. In the in-service use process, after photovoltaic module installs, photovoltaic module's back space is narrow and small, and the terminal box may be sheltered from to the support to the inside change of unable direct observation terminal box.
In the related art, a method for detecting whether the photovoltaic module generates the hot spot effect by coating a layer of optical film (such as an EVA (ethylene vinyl acetate) film) with temperature-sensitive color-changing particles on the surface of the glass cover plate is also disclosed. In this way, when the optical film is disposed on the glass cover plate on the front surface of the solar cell in the photovoltaic module, the glass cover plate may be changed from a transparent color to an opaque color in the presence of the solar cell generating a hot spot effect. The transmittance of sunlight is reduced, and the power generation efficiency of the photovoltaic module is affected. When the optical film is arranged on the glass cover plate positioned on the rear surface of the solar cell, but the heat quantity is reduced gradually, when the heat quantity generated in the photovoltaic module is transferred to the surface of the glass cover plate, the optical film cannot accurately display the temperature change condition. Meanwhile, the specific position of the solar cell generating the hot spot effect cannot be accurately judged by adopting the method.
In the related art, a thermal infrared imager can be used for detecting a solar cell generating a hot spot effect. However, the thermal infrared imager needs more manpower and material resources.
To the technical problem, the embodiment of the utility model provides a photovoltaic module. The photovoltaic module comprises a plurality of solar cells 4, and two adjacent solar cells 4 are electrically connected through a photovoltaic solder strip 100. The photovoltaic solder strip 100 is prepared by improving the photovoltaic solder strip 100 illustrated in fig. 1, so that the solar cell 4 generating the hot spot effect can be timely and accurately determined in the use process of the photovoltaic module, and the whole photovoltaic module is prevented from being damaged.
The photovoltaic solder strip 100 shown in fig. 1 may include a base strip 1 and a tin-lead solder 2 covering the periphery of the base strip 1, where the base strip 1 is typically made of copper. The side of the tin-lead solder 2 in contact with the solar cell 4 is a soldering surface, and the side of the tin-lead solder 2 not in contact with the solar cell 4 is a non-soldering surface.
Fig. 2 illustrates a schematic structural diagram of a photovoltaic solder strip 100 provided by an embodiment of the present invention. Referring to fig. 2, the embodiment of the present invention provides a photovoltaic solder strip 100, which is different from the photovoltaic solder strip 100 shown in fig. 1 in that: the non-welding side of the photovoltaic solder strip 100 shown in fig. 2 has a reversible thermochromic layer 3. For convenience of explanation, the structure of the photovoltaic solder ribbon 100 will be described below according to whether or not it is soldered to the solar cell sheet 4.
Referring to fig. 2, a photovoltaic solder ribbon 100 provided by an embodiment of the present invention includes at least one solder segment bonded to a solar cell sheet 4, and a non-solder surface of each solder segment has a reversible thermochromic layer 3. Each welding section can comprise a base band 1 and tin-lead solder 2 coated around the base band 1. The side of the tin-lead solder 2 in contact with the solar cell 4 is a welding surface, the side of the tin-lead solder 2 not in contact with the solar cell 4 is a non-welding surface, and the non-welding surface of each welding section can be provided with a reversible thermochromic layer 3. Any two adjacent welding sections are connected through the base band 1 coated with the tin-lead solder 2, so that the two solar battery cells 4 electrically connected through the photovoltaic welding strip 100 are electrically connected. Any two adjacent welding segments can be spaced by the same distance, so that the distance between two adjacent solar cells 4 can be equal.
Fig. 3 illustrates a schematic structural diagram of the embodiment of the present invention in which the photovoltaic solder strip 100 is connected to the solar cell 4. Referring to fig. 3, each of the soldering segments is in direct contact with a corresponding solar cell 4, and the soldering segments are made of metal with good thermal conductivity, so that the soldering segments in direct contact with the solar cell 4 can quickly and accurately reflect the temperature of the solar cell 4 generating the hot spot effect. When the temperature of the solar cell sheet 4 reaches a certain temperature, the color of the reversible thermochromic layer 3 changes from the first color to the second color. Meanwhile, the reversible thermochromic layer 3 is only arranged on the non-welding surface of the welding section, so that the transmittance of sunlight cannot be influenced by the color change of the reversible thermochromic layer 3, and the power generation efficiency of the photovoltaic module cannot be influenced. By observing the color change of the reversible thermochromic layer 3, the position of the solar cell 4 generating the hot spot effect can be directly and accurately positioned. It is to be understood that the specific temperature may be a point value temperature or a range value temperature.
In one example, referring to fig. 2, the cross-section of each welding segment may include, but is not limited to, a rectangle, a circle, a triangle, or a trapezoid. In practice, the cross-section of the welding segment may be generally rectangular. When the thickness of the reversible thermochromic layer 3 is D and the thickness of the welding section is D,
the thickness of the reversible thermochromic layer 3 needs to be limited in order not to affect the performance of the solar cell sheet 4. When the thickness of the reversible thermochromic layer 3 is not more than one fifth of the thickness of the welding section, the effect of detecting the solar cell slice 4 generating the hot spot effect can be achieved, and the performance of the solar cell slice 4 cannot be influenced.
In one example, referring to fig. 2, a reversible thermochromic layer 3 may be applied to the entire non-bonding surface. When the reversible thermochromic layer 3 is coated on the surface of the whole non-welding surface, under the condition that the solar cell slice 4 generates the hot spot effect, the specific position of the solar cell slice 4 generating the hot spot effect can be directly observed according to the color change condition of the reversible thermochromic layer 3. Of course, the reversible thermochromic layer 3 may also be applied to the surface of the non-bonding surface at intervals. When the reversible thermochromic layer 3 is coated on the surface of the non-welding surface at intervals, not only can materials be saved, but also the specific position of the solar cell piece 4 generating the hot spot effect can be observed more clearly and directly.
In one example, referring to fig. 2, the reversible thermochromic layer 3 described above may be made of a reversible thermochromic material. When the temperature rises to a specific temperature, the color of the reversible thermochromic material changes, a new color is presented, and the original color can be restored after cooling. That is, the reversible thermochromic material has a color memory function and thus can be repeatedly used. When the temperature of the solar cell sheet 4 reaches a certain temperature, the reversible thermochromic layer 3 is changed from the first color to the second color. The specific temperature is the color change temperature of the reversible thermochromic layer 3.
Referring to fig. 2, the color change temperature of the reversible thermochromic layer 3 may be greater than or equal to 40 ℃ and less than or equal to 150 ℃. In the actual use process, under the condition that the solar cell 4 has a hot spot effect, the temperature of the solar cell 4 can reach about 50 ℃ at the lowest, and can reach 150 ℃ at the highest. Therefore, the color change temperature range of the reversible thermochromic layer 3 needs to be substantially the same as the temperature range when the solar cell sheet 4 exhibits the hot spot effect.
Referring to fig. 2, the reversible thermochromic layer 3 may be made of an inorganic thermochromic material, a metal-organic complex temperature indicating material, or an organic thermochromic material. It is to be understood that the inorganic thermochromic material, the metal organic complex thermochromic material or the organic thermochromic material may be only the main constituent material of the reversible thermochromic layer 3. The following examples are given.
Referring to fig. 2, when the reversible thermochromic layer 3 is made of an inorganic thermochromic material, the inorganic thermochromic material may be a tetraiodomercuric acid-based metal compound. For example: the metallic tetraiodomercuric acid compound comprises Cu2HgI4And/or Ag2HgI4。
In the actual use process, the inorganic thermochromic material has more discoloration mechanisms, wherein an important discoloration mechanism is a crystal form transformation mechanism. When the inorganic thermochromic material is heated to a specific temperature, the inorganic thermochromic material is transformed from one crystal form to another crystal form, thereby transforming the inorganic thermochromic material from a first color to a second color. When the temperature returns to the room temperature, the crystal form of the inorganic thermochromic material is recovered, and the inorganic thermochromic material is changed into the first color from the second color. Most metalates of the tetraiodomercuric acid class have the above-mentioned mechanism of discoloration. In order to timely determine the temperature range of the color transition of the tetraiodomercuric acid metal compound of the solar cell 4 generating the hot spot effect, the temperature range of the color transition of the tetraiodomercuric acid metal compound needs to be generated with the solar cell 4The temperature ranges at which the hot spot effect occurs are substantially the same. For example: cu2HgI4The red color is red under the normal temperature environment, the dark purple color is changed under the environment of 69.6 ℃, and the black color is changed under the environment of 70.6 ℃; ag2HgI4Can be reversibly changed from yellow to red under the environment of 45-50 ℃.
Referring to fig. 2, when the reversible thermochromic layer 3 is made of a metal organic complex temperature indicating material, the metal organic complex temperature indicating material may be a metal copper organic complex temperature indicating material and/or a metal nickel organic complex temperature indicating material. For example: the metal organic complex temperature indicating material comprises [ (C)2H5)2NH2]2 CuCl4And/or [ (CH)3)2CHNH2]CuCl3。
In the actual use process, the main color change mechanism of the metal organic complex is the change of the structure or coordination number. For example: [ (C)2H5)2NH2]2CuCl4The color of the product changes from green to yellow under the environment of 43 ℃; [ (CH)3)2CHN H2]CuCl3It is seen that the color turns from brown to orange in an environment of 52 ℃.
Referring to fig. 2, when the reversible thermochromic layer 3 is made of an organic thermochromic material. The organic thermochromic material is made of a spiro compound, a dianthrone compound, a Schiff base compound, a fluorescent compound or a triphenylmethane compound.
In practical applications, the color change mechanism of the organic thermochromic material can include an intermolecular electron transfer mechanism and an intramolecular structural change mechanism. Organic thermochromic materials based on an intermolecular electron transfer mechanism can generally consist of an electron donor, an electron acceptor, and a solvent compound. Electron donors are typically some fluorans, triphenylmethanes, etc., primarily providing thermochromic bases. The electron acceptor is generally composed of phenols, carboxylic acids, lewis acids, and the like, and mainly causes thermochromism. The solvent is usually aliphatic alcohol, carboxylic ester, ketone, ether, alumina, mainly plays the role of regulating the discoloration temperature. When the temperature changes, electron transfer occurs between the electron donor and the electron acceptor, which causes the molecular structure of the electron donor to change, resulting in a reversible thermochromic phenomenon. The organic thermochromic material based on the intramolecular structural change mechanism is mainly characterized in that the internal structure of the organic thermochromic material is changed under the influence of temperature, so that the color is changed. Structural changes within a molecule may include: intramolecular proton transfer, three-dimensional structure change, crystal form conversion and molecule ring opening.
In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
