Description
Technical Field
The application relates to the technical field of solar cells, in particular to a photovoltaic module.
Background
The photovoltaic module is used as a tool for receiving and converting light energy, has high efficiency after long-term technical updating and iteration, and has wide application in large-scale ground power stations. As the amount of photovoltaic installation increases, ground resource usage has tended to saturate, and a large amount of building area is the best choice for installing photovoltaic as a sunlight receiving surface. The photovoltaic is installed on the building, so that on one hand, the energy income can be increased, on the other hand, the building energy consumption can be reduced, meanwhile, the building power generation can be self-used, and the loss of long-distance power transmission is reduced. However, the photovoltaic cells are usually dark blue or black in color, are monotonous, and cannot meet the appearance requirements of building diversification. Among the technologies of photovoltaic cells are thin film cell technologies such as cadmium telluride, copper indium gallium selenide, etc., which are generally inefficient. Crystalline silicon is used as a mature photovoltaic power generation technology, and the current efficiency reaches more than 24% of mass production efficiency, so that the crystalline silicon is a preferred technology for building photovoltaic integration. The method for realizing the diversified color requirements of the photovoltaic module is to add inorganic or organic pigments into the adhesive film, such as a color adhesive film. On the one hand, the method can greatly reduce the efficiency of the photovoltaic module due to the absorption of the pigment to light, and on the other hand, the method has the risk of fading, so that the method is not a good choice of the color of the photovoltaic module. The method has the advantages that the color coating layer is arranged on the surface of the battery piece, but the color is difficult to be uniform and consistent due to the difficulty in controlling the thickness of the coating layer, and the appearance is difficult to be seen.
On the other hand, the safety performance of the photovoltaic module is very important control performance when the photovoltaic module is used on a building, particularly when the photovoltaic module is used on a vertical surface. The photovoltaic module is used as laminated glass, and after being broken, the packaging adhesive film is not easy to fall from a high place due to the existence of fragments, so that the laminated glass has certain safety property. The strength of this safety attribute is directly related to the characteristics of the packaging adhesive film used, in particular the modulus of elasticity. The common packaging adhesive film comprises EVA, POE, PVB and the like. The physical properties of the adhesive films are that the elastic modulus of the adhesive films gradually decreases along with the rise of temperature, and the EVA, POE and PVB all have glass transition points lower than normal temperature, and the elastic modulus of the adhesive films is greatly reduced when the temperature is higher than 50 ℃. The strength is already weak to a negligible extent compared to glass. However, when the photovoltaic module is used as an electrical appliance unit and is used for outdoor insolation power generation, the working temperature of the photovoltaic module is higher than the ambient temperature by thirty-forty degrees. Such as Xia Tianshi, temperatures up to 80 c and even higher. At this temperature, the inside EVA of photovoltaic module, POE, PVB etc. encapsulation glued membrane intensity can be very low, if the subassembly receives external force to take place to damage this time, just probably takes place to fall under the dead weight after the subassembly after the damage and hurts the people. The summer is a season with extreme weather high occurrence such as hail and wind, and the risk is very high.

Detailed Description
Exemplary embodiments of the present application are described below, including various details of embodiments of the present application to facilitate understanding, which should be considered as merely exemplary. Accordingly, one of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness. The upper and lower positions in this application depend on the direction of incidence of the light, where the light is incident.
The existing photovoltaic module mainly uses EVA or POE as a packaging material, and the packaging structure can meet the reliability requirement of the photovoltaic, but can not meet the requirements of the anti-flexing deformation and the safety performance of the photovoltaic laminated glass in building application scenes such as curtain walls, daylighting roofs and the like due to lower elastic modulus and tensile strength of the EVA and the POE. Wherein the safety performance is a key performance requirement of the building on the laminated glass. PVB is often used for packaging laminated glass in buildings, so that the packaging material of a common curtain wall photovoltaic module also needs to be packaged by PVB. However, since the photovoltaic module actually works because the current exists in the module, most sunlight entering the photovoltaic module cannot be converted into electric energy but is converted into heat energy, a large amount of heat is generated, the heat dissipation speed is not very high, the temperature of the module in actual work is far higher than the ambient temperature, the temperature in the module can reach more than 50 ℃ at the ambient temperature of 25 ℃, and the maximum temperature can reach more than 80 ℃ when the ambient temperature rises and the sunlight irradiation amount is large. And EVA, POE and PVB are used as elastoplastic polymer materials, when the temperature is higher than 25 ℃, the elastic modulus of the EVA, POE and PVB is greatly reduced along with the temperature rise, and when the temperature is higher than 50 ℃, the elastic modulus of the EVA, POE and PVB is reduced to below 2MPa, and the elastic modulus is far lower than the elastic modulus of 70GPa of glass. In such a normalized high temperature environment, the flexural modulus of the photovoltaic laminated glass is also greatly reduced, and the safety property as a safety glass is also meaningless due to the great reduction of the modulus and strength of the adhesive film at high temperature.
Based on this, the application provides a photovoltaic module, and it includes backplate, first lower flexible glued membrane layer 7, the flexible glued membrane layer 6 of reinforcement, second lower flexible glued membrane layer 5, battery piece layer 4 and the front bezel of range upon range of setting in proper order.

In the present application, the upper colored glass layer is an interference colored glass layer, and due to the high transmittance and low reflectivity, when a material with high visible light reflectivity exists below the upper colored glass layer, the visible light waves reflected by the upper colored glass layer are mixed with the visible light waves reflected below the upper colored glass layer, and at this time, the color seen by the human eye is different from the color reflected by the upper colored glass layer. Therefore, the material with full black or near black color below the upper colored glass layer is required to absorb the visible light transmitted by the glass, and the light received by human eyes above the upper colored glass layer is mainly reflected light generated by interference of inorganic color powder in the upper colored glass layer, so that the true color of the upper colored glass layer is seen.
In this application, the upper colored glass layer has an antiglare structure.
Specifically, an antireflection layer is disposed on a surface of the front glass layer 1 facing away from the colored glaze layer 2, so as to improve light transmittance.
In this application, upper transparent layer is from the bottom up including upper adhesive film layer 3 and the front glass layer 1 that set gradually, just upper adhesive film layer 3 deviate from the front glass layer 1 a side surface with battery piece layer 4 links together.

The transparent adhesive film layer may be EVA, POE, PVB, SGP, or the like, including but not limited to.
The front glass layer 1 is transparent glass, and the thickness of the transparent glass layer is 1-16mm, for example, 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm or 16mm.
The application provides a preparation method of a photovoltaic module, which comprises the following steps:
step one: a back-plate is provided which,
step two: providing a three-layer composite film, wherein the three-layer composite film comprises a first lower flexible adhesive film layer 7, a reinforced adhesive film layer 6 and a second lower flexible adhesive film layer 5 which are sequentially laminated together;
step three: stacking the first lower flexible glue film layer 7 and the back plate together;
step four: a battery piece layer 4 is arranged on the surface of one side of the second lower flexible adhesive film layer 5, which is away from the reinforced adhesive film layer 6;
step five: the front plate is arranged on the surface of one side of the battery piece layer 4, which faces away from the second lower flexible adhesive film layer 5.
In the first step, the back plate is one of a back glass layer, an aluminum back plate, a PET back plate, a PE back plate and an EVE back plate.
In the second step, after corona treatment is performed on the two surfaces of the reinforced adhesive film layer 6, the two surfaces are respectively pressed together with the first lower flexible adhesive film layer 7 and the second lower flexible adhesive film layer 5, so that three layers of composite films are formed.
When the reinforced adhesive film layer 6 is a PET film layer, the surface activity of the PET film and the surface coating of the PET film is generally lower, the adhesiveness to the flexible adhesive film is lower, and in order to enhance the adhesiveness, the surface of the PET film is generally subjected to plasma corona treatment when leaving a factory, so that rich suspension bonds are formed on the surface of the PET film, the PET film and the flexible adhesive film form chemical bonds, and firm bonding is generated, so that the PET film and the flexible adhesive film after the corona can be directly laminated in a laminating machine, and the three-layer composite film is formed. PET as a thermosetting material has an elastic modulus of about 1 to 2GPa at normal temperature, and the breaking strength can reach more than 120MPa, which is higher than that of toughened glass. Even if the temperature is raised to 75 ℃, the elastic modulus still exceeds 1GPa, and the strength is not lost. Thus, the device works normally at higher ambient temperatures, and the presence of the PET film layer allows the three-layer composite film to still have high modulus and high strength when the assembly temperature reaches 60 to 80 ℃. Thus, even if the device is subjected to abnormal external force at a high temperature of 80 ℃, when the back glass layer 8 or the front glass layer 1 is broken, the high-strength and toughness PET film layer can be attached to the flexible adhesive films such as the first lower flexible adhesive film layer 7 and the second lower flexible adhesive film layer 5, so that broken glass fragments can be adhered to prevent the broken glass fragments from falling in a lump and injuring pedestrians below a high-rise building. If the PET film is not made of such high-temperature rigid materials, when the device is broken, the dead weight of glass fragments can be fully loaded on the first lower flexible film layer 7, the second lower flexible film layer 5 and the upper flexible film layer which have lower high-temperature strength, so that the film is stretched and deformed until the device is broken, and the large glass fragments are separated from the assembly to fall, so that potential safety hazards can be generated. Therefore, the PET adhesive layer with high strength at high temperature can ensure that the assembly keeps high flexural deformation resistance and high impact resistance, namely has high safety performance. The PET adhesive film high-strength material can also be replaced by PU, nylon or a wire mesh material, and the material has higher strength, can have stronger anti-falling capability when the component is broken, and has higher safety performance.
In the fifth step, the front plate is an upper colored glass layer or an upper transparent layer.
The photovoltaic module prepared by the preparation method is the photovoltaic module, and the back plate, the first lower flexible adhesive film layer, the reinforced adhesive film layer, the second lower flexible adhesive film layer, the battery piece layer and the front plate can be referred to the description in the photovoltaic module.

The small knot: as can be seen from table 1, the color photovoltaic module according to the present application uses the color ink to print glass to realize the color of the front glass, and the use of the pearl powder or the multi-layer oxide nano toner ensures that the glass realizes the color while maintaining high light transmittance, thereby ensuring high efficiency of the photovoltaic module. The photovoltaic module is guaranteed to meet the appearance requirement of the building field, and meanwhile, the power generation property of the photovoltaic module core is maintained to the highest degree. On the packaging material, the unique flexible adhesive film, the rigid adhesive film and the flexible adhesive film are used, and the use of the rigid material layer ensures the high strength of the photovoltaic module, particularly the post-damage strength, namely the module is damaged, and the falling can not occur due to insufficient adhesive film strength, particularly the falling of the flexible adhesive film under the high temperature condition. The safety core attribute of the photovoltaic module used on the building curtain wall is guaranteed. The black weather-resistant layer of the rigid adhesive film layer is the necessary composition for the color development of pearl powder and multi-layer oxide nano-toner. Light reflected by the back material of the photovoltaic module can pass through the gap and be secondarily reflected to the surface of the cell by the glass interface so as to be absorbed by the cell, and power gain is generated. The infrared high-reflection coating structure can generate power gain, so that the efficiency of the photovoltaic module is further improved, and extra benefits are brought.
