Description

Technical Field

[0001] The invention relates to the technical field of full-color optoelectronic materials, and in particular to a method for preparing a full-color optoelectronic functional material with a heating function. Background Art

[0002] The full-color optoelectronic functional material is covered with a highly transparent velvet conductive film or layer. The uneven velvet surface increases the refraction and scattering of light, allowing the full-color optoelectronic functional material to absorb light from multiple angles and improve the utilization rate of light. In addition, the conductive film collects current to power the external semiconductor heating film so that it can be applied to the required scene.

[0003] A Chinese patent with announcement number CN118352433A discloses a method for preparing an easy-to-clean full-color optoelectronic functional material, which relates to the field of solar photovoltaic technology. The method for preparing an easy-to-clean full-color optoelectronic functional material proposed in the present invention effectively avoids the interference of pollutants on the preparation process through cleaning and plasma activation treatment in a dust-free environment, ensures good adhesion and uniform distribution of the coating, and the easy-to-clean coating formed by the fluorocarbon antifouling coating has a super-hydrophobic property, so that dust and dirt are not easily adhered to the surface of the full-color optoelectronic functional material, significantly reducing the difficulty and cost of maintenance and cleaning. The wear resistance and scratch resistance of the coating are enhanced, so that the full-color optoelectronic functional material can maintain the novelty and integrity of the appearance even in harsh environments, and the anti-ultraviolet performance of the coating ensures that the full-color optoelectronic functional material is not easy to age and fade when exposed to sunlight for a long time, ensuring the stability and durability of the photoelectric conversion efficiency.

[0004] However, the above-mentioned disclosed scheme has the following shortcomings: the above-mentioned method increases the smoothness of the surface of the photovoltaic module by adopting a hydrophobic layer and a fluoride, thereby reducing the adhesion of dust and dirt on the surface of the photovoltaic module. However, in actual use, the blocking effect of snow on the photovoltaic module is much greater than the shielding effect of dust and dirt. However, the above-mentioned method does not have the ability to clean the snow-covered situation. Summary of the invention

[0005] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of the present invention to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0006] The purpose of the present invention is to address the technical problems existing in the background technology. The present invention proposes a method for preparing a full-color optoelectronic functional material with a heating function. The present invention can effectively improve the use efficiency of photovoltaic modules in a snowy environment through this method. The combination of a conductive film and a heating film can achieve the effect of adaptive heating of the method, so that when the photovoltaic module is covered with snow, the heating film can be automatically started to heat the snow, thereby accelerating the speed at which the snow slides off and ensuring the stable working efficiency of the photovoltaic module.

[0007] The present invention proposes a method for preparing a full-color optoelectronic functional material with a heating function, comprising the following steps:

[0008] S1 is a step of performing a dust-free treatment on the surface of the photovoltaic module. In this step, the surface of the photovoltaic module is cleaned by a cleaning mechanism to reduce dust on the surface of the photovoltaic module, so that the surface of the photovoltaic module is in a clean state to ensure the stability of the subsequent film processing on the surface of the photovoltaic module;

[0009] S2 is a step of laminating a full-color micro-layer film on the surface of a photovoltaic module. In this step, the full-color micro-layer film is laminated on the surface of the photovoltaic module. The full-color micro-layer film can change the frequency of natural light when the natural light passes through the full-color micro-layer film, thereby changing the visible light spectrum in the natural light. The full-color micro-layer film can change the various frequencies in the natural light into light frequencies that are convenient for conversion by the photovoltaic module;

[0010] S3 is a step of laminating a conductive film on the surface of the full-color micro-layer film. This step can generate a weak current independent of the photovoltaic module by laminating the conductive film on the outside of the full-color micro-layer film, so that the subsequent power-using steps are not affected by whether the photovoltaic module is turned on. The structure of the conductive film can generate a weak current inside the conductive film when it is irradiated by light, providing power for subsequent links;

[0011] S4 is a step of adhering a velvet surface to the surface of the conductive film. In this step, the velvet structure can prevent the surface of the conductive film from generating mirror reflection, thereby improving the light collection efficiency of the photovoltaic module and the conductive film. The irregular surface of the velvet can improve the diffuse reflection efficiency of light. Compared with the light reflected by the mirror, the light reflected by the diffuse reflection is more easily collected by the photovoltaic module and the conductive film for a second time, thereby improving the light collection efficiency of the conductive film and the photovoltaic module.

[0012] S5 is a step of installing a semiconductor heating film on the outer side of the velvet surface. In this step, a grid-type heating film is installed on the outer side of the velvet surface to generate heat after a weak current is generated in the conductive film and the heating is turned on, thereby heating and melting the snow on the surface of the velvet surface. The use of the grid-type heating film can reduce the shielding effect of the heating film on the conductive film and the photovoltaic module. At the same time, the grid-type heating film can make the heating effect more concentrated, thereby accelerating the breaking speed of the equilibrium state of the snow, so that the snow slides down faster after being heated;

[0013] S6 is a step of installing a pressure sensor or a visual detection system on the surface of the semiconductor heating film. In this step, the pressure sensor or the visual detection system can detect whether there is snow squeezing on the surface of the photovoltaic module and the multi-layer film structure, and then determine whether heating and snow melting are currently required;

[0014] S7: establishing a step of electrically connecting the conductive film and the semiconductor heating film. In this step, the conductive film and the heating film are electrically connected so that a weak current can enter the heating film when the conductive film is illuminated, thereby achieving a heating effect on the surface of the photovoltaic module.

[0015] S8 is a step of establishing a control connection between the conductive film and the pressure sensor or the visual detection system. This step controls the opening and closing of the conductive film through the pressure sensor or the visual detection system, thereby achieving a control effect on the heating film, thereby starting the heating film when there is snow accumulation.

[0016] By adopting the above technical solution, this solution can make the photovoltaic module adapt to the snowy environment by adding a heating structure on the surface of the traditional photovoltaic module, and can work stably in the snowy environment.

[0017] Preferably, in step S1, dust is removed from the photovoltaic module by a dust suction structure to avoid uneven lamination of the full-color micro-layer film due to dust, while ensuring close contact between the full-color micro-layer film and the surface of the photovoltaic module.

[0018] By adopting the above technical solution, the present solution can adjust the visible light spectrum through full-color micro-layer film, so that the frequency of the natural light spectrum is more concentrated to facilitate the lighting conversion of photovoltaic components.

[0019] Preferably, in the step S2, the full-color micro-layer film is laminated by a pressing roller, and the pressing roller can uniformly squeeze the full-color micro-layer film, thereby reducing the local pressure on the surface of the photovoltaic module during the laminating process.

[0020] By adopting the above technical solution, this solution can avoid damaging the surface of the photovoltaic module during the bonding process through uniform bonding and extrusion. At the same time, the uniform extrusion of the full-color micro-layer film can avoid the deformation of the prism structure inside the full-color micro-layer film that produces a color-changing effect on visible light.

[0021] Preferably, in step S4, an adhesive coating is applied to the surface of the conductive film, so that the fluff is adhered when passing through the surface of the conductive film, thereby forming a suede effect, and the suede can protect the surface of the conductive film.

[0022] By adopting the above technical solution, the present solution produces a suede effect by adhesion, which can reduce the risk of the suede structure falling off from the surface of the conductive film.

[0023] Preferably, in step S5, the semiconductor heating film generates heat uniformly when powered on, so that the conductive film can control the heating film to melt the snow. The grid-type semiconductor heating film structure can ensure the effect of melting the snow while avoiding affecting the lighting efficiency of the photovoltaic module.

[0024] By adopting the above technical solution, the present solution can reduce the thickness and weight of the heating film by means of semiconductor heating, thereby avoiding the influence of the present method on the traditional photovoltaic modules.

[0025] Preferably, in step S6, a pressure sensor or a visual detection system is used to control the opening and closing of the heating film, thereby avoiding the heating film from working continuously for a long time and reducing the waste of ineffective energy.

[0026] By adopting the above technical solution, the present invention controls whether the heating film is working by means of pressure sensing, thereby avoiding manual operation control and reducing the manual maintenance cost of the present device.

[0027] In summary, the present invention includes at least one of the following beneficial effects:

[0028] This method can overcome the problem that photovoltaic modules cannot work in snowy environments. The combination of conductive film and heating film can realize that this method is completely independent of the existing photovoltaic module structure, reducing the difficulty of the combination and installation of the device while having effective compatibility with a variety of photovoltaic module structures. Through control and adjustment through structures such as pressure sensors, problems such as damage to the heating film caused by long-term continuous heating can be avoided. At the same time, this method improves the photovoltaic module to avoid affecting the original lighting area of ​​the photovoltaic module. At the same time, by bonding the full-color micro-layer film, it can ensure that the photovoltaic module can stably light up a variety of different visible light spectra.

This step controls the opening and closing of the conductive film through the pressure sensor or the visual detection system, thereby achieving a control effect on the heating film, thereby starting the heating film when there is snow accumulation.

[0042] This method uses a multi-layer film structure to be installed on the surface of a traditional photovoltaic module, which can reduce the difficulty of installing the device while being compatible with existing photovoltaic modules to the greatest extent. At the same time, this device uses a full-color micro-layer film to adjust the spectrum of natural light, thereby facilitating the photovoltaic module to perform lighting conversion. The velvet structure can effectively avoid mirror reflection after the installation of this solution, ensuring that light is diffusely reflected when irradiated on the surface of the film of this solution, thereby achieving a secondary absorption effect of light.

[0045] In the step S2, the full-color micro-layer film is laminated by a pressing roller. The pressing roller can evenly squeeze the full-color micro-layer film, thereby reducing the local pressure on the surface of the photovoltaic module during the lamination process.

[0046] In the step S4, an adhesive coating is applied to the surface of the conductive film, so that the fluff is adhered when passing through the surface of the conductive film, thereby forming a suede effect, and the suede can protect the surface of the conductive film.

[0047] In the step S5, the semiconductor heating film generates heat uniformly when powered on, so that the conductive film can control the heating film to melt the snow. The grid-type semiconductor heating film structure can ensure the effect of melting the snow while avoiding affecting the lighting efficiency of the photovoltaic module.

[0048] In the step S6, a pressure sensor or a visual detection system is used to control the opening and closing of the heating film, thereby avoiding the heating film from working continuously for a long time and reducing the waste of ineffective energy.

[0049] Compared with the traditional method, this solution adds a heating structure to the surface of the traditional photovoltaic module so that the photovoltaic module is not blocked by snow, thereby extending the effective use time of the photovoltaic module and improving the use efficiency of the photovoltaic module.

[0050] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention.
