Optimizing the combined structure to adapt it to the needs of a variety of scenarios is an important topic in promoting the popularization of photovoltaic-thermal technology.

The snap-on photovoltaic thermal coupling structure is also suitable for environments with irregular surfaces on the surface of buildings or other surfaces, requiring quick installation and easy later maintenance, and is commonly used in building photovoltaic integration, parking lot photovoltaic roof systems, etc. In addition, the snap-on photovoltaic thermal coupling structure is also suitable for photovoltaic thermal systems with modular design, especially systems that require free combination, scalability or flexible use, such as solar collector modules, photovoltaic modules and other quickly replaceable systems.

[0045] The preparation of semi-transparent photovoltaic cells, the preparation of photothermal reflectors and the specific method of coupling the two are described in detail below.

[0046] 1. Preparation process of semi-transparent photovoltaic cells

[0047] The semi-transparent photovoltaic cell of this embodiment can be a semi-transparent perovskite solar cell, a semi-transparent quantum dot solar cell, a semi-transparent dye-sensitized solar cell or a semi-transparent organic solar cell. The structure of the semi-transparent photovoltaic cell 1 can be sequentially arranged as follows: substrate, first transparent electrode, electron transport layer, light absorption layer, hole transport layer, second transparent electrode, encapsulation layer, including multiple possibilities of all layers existing or some layers not existing. The specific preparation process is as follows:

[0048] Preparation of substrate

[0049] Substrate material: Select a transparent substrate material, such as glass material or flexible polymer material, etc., among which the flexible polymer material can be PET material, PI material, etc.

[0050] The substrate is made of glass or flexible polymer material, and then ultrasonically cleaned with deionized water, ethanol and acetone to remove surface impurities. The substrate is then blown dry with nitrogen and the surface of the substrate is treated with UV-Ozone or plasma to improve wettability.

[0051] Preparation of the first transparent electrode

[0052] The first transparent electrode material: generally ITO (indium tin oxide) or FTO (fluorine-doped tin oxide) material is selected.

[0053] A thin film is deposited on a substrate by magnetron sputtering or thermal evaporation to form a first transparent electrode, and then the first transparent electrode is annealed. The annealing temperature is controlled at 500°C and the annealing time is controlled at 30 minutes to improve conductivity and light transmittance.

[0054] Preparation of electron transport layer

[0055] Electron transport layer materials: usually titanium dioxide, tin dioxide, C60 and other materials are selected.

[0056] The electron transport layer is prepared by spin coating or slit coating, the spin coating speed can be set to 5000 rpm, the spin coating time can be controlled at 30 seconds, and then annealed in air, the annealing temperature is controlled at 150° C., and the annealing time is controlled at 30 minutes.

[0057] Preparation of light absorbing layer

[0058] Light absorption layer material: perovskite material (such as methylammonium lead iodide or triple cation mixed halide perovskite, etc.) is used.

[0059] First, prepare the perovskite precursor solution, and then coat the perovskite layer on the electron transport layer by spin coating or slit coating. During the spin coating process, add anti-solvents such as chloroform or toluene to induce perovskite crystallization. Then put the prepared substrate into a hot plate for heating and annealing. The annealing temperature is controlled at 100°C and the annealing time is controlled at 20 minutes to form a uniform light absorption layer.

[0060] Preparation of hole transport layer

[0061] Hole transport layer material: Spiro-OMeTAD or PEDOT:PSS material.

[0062] The hole transport layer is prepared on the perovskite light absorption layer by spin coating or slot coating, and then placed in air to promote doping.

[0063] Preparation of the second transparent electrode

[0064] Second transparent electrode material: generally ultra-thin metals (such as Au, Ag, etc.) or transparent conductive oxides (such as ITO, FTO, etc.) are selected.

[0065] The second transparent electrode is deposited on the hole transport layer by using methods such as magnetron sputtering and electron beam evaporation.

[0066] Preparation of encapsulation layer

[0067] Encapsulation layer material: Choose epoxy resin or polymer film.

[0068] The selected encapsulation layer material is used to cover the entire device to prevent moisture and oxygen in the environment from corroding the perovskite material. The encapsulation is performed under vacuum and UV curing or heat pressing is performed.

[0069] 2. Preparation process of photothermal reflector

[0070] The structure of the photothermal reflector of this embodiment can be sequentially arranged as follows: glass substrate, metal coating, spectrum separation layer and nano anti-reflection coating. The preparation process of the photothermal reflector includes the steps of selecting the material of the reflector, molding process, setting of the spectrum separation layer, deposition of the nano anti-reflection coating and the like. The photothermal reflector realizes more efficient light energy utilization through the multiple settings of the spectrum separation layer and the nano anti-reflection coating. The specific preparation process is as follows:

[0071] Preparation of the reflector body:

[0072] Metal coating material: Choose metal materials such as aluminum or silver with high reflectivity.

[0073] A metal material is coated on a glass substrate to form a reflector body to ensure that the reflectivity is above 90%. The reflector body can adopt a planar structure or a curved structure.

[0074] When the main body of the reflector adopts a curved structure, the glass substrate needs to be processed into a micro-curved or curved surface through hot bending or vacuum forming technology. Alternatively, a flexible polymer substrate material (such as PI film) is used to replace the glass substrate to make the reflector lightweight and impact-resistant.

[0075] Preparation of spectral separation layer:

[0076] Materials for the spectrum separation layer: select materials such as silicon dioxide and aluminum oxide.

[0077] Using electron beam evaporation, silicon dioxide and aluminum oxide are alternately deposited on the surface of the reflector body. The thickness of each layer of silicon dioxide and each layer of aluminum oxide is controlled between 5 and 100 nanometers, ensuring high reflectivity of ultraviolet-visible light and allowing infrared light to pass through.

[0078] Preparation of Nano Anti-reflective Coating:

[0079] Materials for nano anti-reflective coating: Choose hydrophobic and high temperature resistant materials, such as silica, fluoride and other materials.

[0080] A nano anti-reflection coating is deposited on the surface of the spectrum separation layer by a sol-gel method or an electron beam evaporation method to ensure uniform distribution and improve the light transmission performance of the reflector. Among them, the thickness of the nano anti-reflection coating is controlled at 100 to 200 nanometers to reduce light reflection losses and improve the weather resistance of the reflector. Self-cleaning nanoparticles (such as titanium dioxide) can also be used as additives for the nano anti-reflection coating to give the mirror a self-cleaning function while maintaining high light transmittance. The nano anti-reflection coating is then subjected to plasma surface treatment to improve its chemical stability in high temperature environments.

[0081] Finally, the prepared photothermal reflector is placed under simulated high temperature conditions for aging testing to ensure that the photothermal reflector maintains efficient optical performance after long-term exposure to a high temperature environment.

[0082] 3. Coupling process of semi-transparent photovoltaic cells and photothermal reflectors

[0083] As an efficient and flexible photovoltaic-thermal coupling connection method, the snap-on method can achieve a stable connection between semi-transparent photovoltaic cells and photothermal reflectors through a variety of design schemes. This method not only has a simple construction process, but also can effectively improve the stability and reliability of the system, and is suitable for photovoltaic-thermal coupling systems in various environments. Among them, the form of the snap-on can be selected according to actual needs, such as the existing threaded locking snap-on, elastic locking snap-on, suction cup snap-on, and snap-on with self-locking function, to ensure that the operation is convenient during the installation process and the photovoltaic cells can be firmly fixed.

[0084] The first method is to use a four-corner clip fixing method. This method installs clips at the four corners of the photothermal reflector to tightly fix the translucent photovoltaic cell to the surface of the photothermal reflector. The locking function of the clip can ensure a tight fit between the cell and the reflector to prevent the structure from loosening or failing due to external forces. The clip material used needs to have high strength and weather resistance. Usually, materials with excellent heat resistance and UV resistance such as polyimide (PI) or polycarbonate (PC) are selected to ensure that it is not affected by bad weather in a long-term outdoor environment.

[0085] The second method is to use a multi-point buckle fixing method. This method evenly arranges multiple buckles along the four sides of the photothermal reflector, and firmly fixes the translucent photovoltaic cell on the surface of the photothermal reflector through the locking function of the buckle. This method is suitable for photovoltaic cells and reflectors of larger sizes or irregular shapes, and can provide a more uniform force distribution, reducing the deformation or stress concentration of photovoltaic cells caused by thermal expansion and contraction. The spacing of the buckles can be adjusted according to actual use requirements to further improve the adaptability and reliability of the system. The selected materials are also mainly high-strength weather-resistant materials to ensure long-term stability in different environments.

[0086] The third method is a fixing method that combines four-corner buckles with multi-point buckles. This method not only installs buckles at the four corners of the photothermal reflector, but also evenly arranges multiple buckles along the four sides of the photothermal reflector, and firmly fixes the translucent photovoltaic cell on the surface of the photothermal reflector through the locking function of the buckle. This method integrates the advantages of the four-corner buckle fixing method and the multi-point buckle fixing method, greatly improving the connection stability between the translucent photovoltaic cell and the photothermal reflector, reducing the deformation or stress concentration of the photovoltaic cell due to thermal expansion and contraction, and preventing the structure from loosening or failing due to external forces.

[0087] The fourth method is to slide the translucent photovoltaic cell onto the surface of the photothermal reflector by using the limiting function of the guide groove and the buckle, and then secure it firmly by locking it with the buckle. This method can accurately control the position of the photovoltaic cell and ensure its installation accuracy. The guide groove is made of highly wear-resistant polytetrafluoroethylene (PTFE) material, which has good sliding and wear resistance, and effectively reduces the friction and wear between the photovoltaic cell and the photothermal reflector. The locking function of the buckle ensures the long-term stability between the photovoltaic cell and the reflector, and is easy to maintain and replace, greatly improving the reliability and economy of the system.

[0088] Several snap connection methods are described in detail below.

[0089] Elastic locking snap-on connection: This method combines the functions of springs and snaps, and uses elastic force to achieve a firm connection between the snap and the surface of the photovoltaic cell or thermal reflector. When in use, the snap fixes the photovoltaic cell to the surface of the thermal reflector through the tension of the spring and keeps it tight through mechanical force. The advantage of the spring snap-on connection is that it can effectively relieve the stress caused by thermal expansion and contraction, especially in environments with large temperature changes. This method is suitable for systems that are sensitive to temperature changes, such as thermal power generation systems in high-temperature areas.

[0090] Threaded locking snap-on connection: The threaded snap-on firmly connects the snap-on to the photovoltaic cell or solar thermal reflector through the threaded structure. Compared with the traditional snap-on method, the threaded snap-on can provide a stronger locking force to ensure the stability of the connection over a long period of time. During installation, the outer structure of the threaded snap-on can be rotated to achieve fixation, thereby forming a reliable coupling structure. This method is particularly suitable for applications that require long-term use and have high requirements for connection strength, especially in high-temperature environments where loosening is not allowed.

[0091] Suction cup buckle connection: The suction cup buckle uses the vacuum adsorption characteristics of the suction cup to create negative pressure between the surfaces of the photovoltaic cell and the photothermal reflector, thereby achieving a tight connection between the two. The advantage of this method is that it can achieve fast and lossless connection and disassembly, which is particularly suitable for scenes that require frequent disassembly or maintenance. The suction cup buckle is suitable for situations where the materials of the photovoltaic cell and the photothermal reflector are relatively smooth and there are not too many irregular protrusions on the surface. This method can also maintain good connection performance in low temperature and high humidity environments.

[0092] Self-locking snap-on connection: A snap-on with automatic locking function is used to tightly lock the photovoltaic cell and the solar thermal reflector through the self-locking function of the snap-on. This self-locking snap-on connection method ensures that even if the alignment is not complete during the installation process, the final tightening can be automatically completed through the self-locking mechanism, avoiding the influence of human operation errors. The self-locking snap-on is very suitable for fast-assembly photovoltaic and solar thermal coupling systems, which can reduce the complexity of manual assembly and improve work efficiency. It usually has strong mechanical stability and is suitable for large-scale production and on-site installation.

[0093] The various buckles mentioned above all adopt the existing buckle structures on the market, so the specific structural form of the buckle will not be described in detail. You only need to select the corresponding buckle according to actual usage requirements.

[0094] Each snap-on connection method is adapted to specific application environments and requirements. For example, elastic snaps are suitable for areas with large thermal expansion and contraction, suction cup snaps are suitable for scenarios that require high-frequency maintenance, and self-locking and threaded snaps are suitable for large-scale production and applications with high requirements for connection stability. Choosing the appropriate snap-on method can be determined based on actual environmental conditions, maintenance requirements, and system stability, thereby ensuring efficient operation and long-term stability of the photovoltaic-thermal coupling system.

[0095] In summary, the snap-on photovoltaic thermal coupling structure made by this embodiment has significant advantages over the traditional fixed coupling system. In terms of weather resistance, the photovoltaic thermal coupling system with snap-on technology needs to have strong adaptability and be able to work stably in an environment with large temperature changes. The system can withstand high temperatures ranging from 80°C to 150°C and maintain its shape and function without being affected by thermal expansion. At the same time, the material of the buckle has good UV resistance. After the UV aging test, there will be no cracks, shedding or discoloration on the surface, and the UV aging test time should reach more than 2000 hours. In addition, the buckle is also very resistant to corrosion and can work for at least 500 hours in a salt spray environment without obvious corrosion or damage.

[0096] In addition, the photovoltaic-thermal coupling structure using snap-on technology shows significant advantages in terms of easy replacement and reduced maintenance costs. Specifically, the use of snap-on connection can reduce the maintenance time and maintenance costs when the system fails. Compared with the traditional fixed connection method, the snap-on structure can save about 30% of the maintenance time each time the photovoltaic cell or photothermal reflector needs to be disassembled and replaced, usually from 4 hours in the traditional method to about 2.8 hours. In terms of maintenance costs, the application of the snap-on structure reduces the annual average operation and maintenance costs by at least 15% to 20%. By simplifying the disassembly and replacement process, labor costs and equipment downtime are reduced, and due to the high reliability and durability of the snap, the failure rate of the equipment is also reduced accordingly. This means that the long-term operating costs of the system can be greatly reduced, especially in application scenarios where photovoltaic cells or photothermal reflectors need to be replaced frequently. In addition, the snap-on structure also reduces the additional maintenance costs caused by equipment damage, further improving the economy and maintainability of the system.

[0097] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
