Description

Technical Field

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

[0002] The full-color optoelectronic functional material is covered with a high-transmittance textured conductive film or layer. The uneven textured surface increases light refraction and scattering, allowing the full-color optoelectronic functional material to absorb light from multiple angles and improve light utilization. In addition, the conductive film collects current to power an external semiconductor heating film for application in the required scenarios.

[0003] Chinese Patent No. CN118352433A discloses a method for preparing an easy-clean full-color optoelectronic functional material, relating to the field of solar photovoltaic technology. The method proposed in this invention effectively avoids interference from contaminants during the preparation process through cleaning and plasma activation treatment in a dust-free environment, ensuring good adhesion and uniform distribution of the coating. The easy-clean coating formed by the fluorocarbon anti-fouling coating has superhydrophobic properties, making it difficult for dust and dirt to adhere to the surface of the full-color optoelectronic functional material, significantly reducing the difficulty and cost of maintenance and cleaning. The enhanced wear resistance and scratch resistance of the coating allow the full-color optoelectronic functional material to maintain its novelty and integrity even in harsh environments. The UV resistance of the coating ensures that the full-color optoelectronic functional material is not prone to aging and fading under long-term exposure to sunlight, ensuring the stability and durability of the photoelectric conversion efficiency.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: The above methods increase the smoothness of the photovoltaic module surface by using a hydrophobic layer and fluorides, thereby reducing the adhesion of dust and dirt to the photovoltaic module surface. However, in actual use, the blocking effect of snow on the photovoltaic module is much greater than the blocking effect of dust and dirt. However, the above methods do not have the ability to clean snow cover. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the invention, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] The purpose of this invention is to address the technical problems existing in the background art. This invention proposes a method for preparing a full-color optoelectronic functional material with heating function. This invention can effectively improve the utilization efficiency of photovoltaic modules in snowy environments. By combining a conductive film and a heating film, this method can achieve an adaptive heating effect. Thus, when the photovoltaic module is covered by snow, the heating film can be automatically activated 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] This invention proposes a method for preparing a full-color optoelectronic functional material with heating function, comprising the following steps;

[0008] S1 is a dust-free treatment step for the photovoltaic module surface. This step uses a cleaning mechanism to clean the photovoltaic module surface, reducing dust and ensuring that the photovoltaic module surface is in a clean state to ensure the stability of subsequent film application processing on the photovoltaic module surface.

[0009] S2 is the step of laminating a full-color microfilm onto the surface of a photovoltaic module. This step involves laminating a full-color microfilm onto the surface of the photovoltaic module. The full-color microfilm can change the frequency of natural light when it passes through the full-color microfilm, thereby changing the visible light spectrum in natural light. The full-color microfilm can change multiple frequencies in natural light into light frequencies that are easy for the photovoltaic module to convert.

[0010] S3 is the step of bonding a conductive film to the surface of the full-color microfilm layer. This step generates a weak current independent of the photovoltaic module by bonding a conductive film to the outside of the full-color microfilm layer. This allows subsequent power consumption steps to be unaffected by whether the photovoltaic module is turned on or off. The structure of the conductive film allows a weak current to be generated inside the conductive film when it is exposed to light, providing power for subsequent steps.

[0011] S4 is a step of attaching a textured surface to the conductive film. This step uses the textured surface structure to avoid specular reflection on the conductive film surface, thereby improving the light-gathering efficiency of the photovoltaic module and the conductive film. The irregular surface of the textured surface can improve the diffuse reflection efficiency of light. The diffusely reflected light is more easily collected by the photovoltaic module and the conductive film than the specularly reflected light, thus improving the light-gathering efficiency of the conductive film and the photovoltaic module.

[0012] S5 is the step of installing a semiconductor heating film on the outer side of the velvet surface. This step involves installing a grid-type heating film on the outer side of the velvet surface, which generates a weak current in the conductive film and heats up after the heating is turned on, thereby heating and melting the snow on the velvet surface. Using a grid-type heating film can reduce the shading effect of the heating film on the conductive film and photovoltaic modules. At the same time, the grid-type heating film can make the heating effect more concentrated, thereby accelerating the breaking of the snow's equilibrium state and making the snow slide off faster after being heated.

[0013] S6 is the step of installing a pressure sensor or visual inspection system on the surface of the semiconductor heating film. This step can detect whether there is snow accumulation and compression on the surface of the photovoltaic module and the multilayer film structure through the pressure sensor or visual inspection system, and then determine whether heating to melt the snow is needed.

[0014] S7 establishes an electrical connection between the conductive film and the semiconductor heating film. This step ensures that a weak current can enter the heating film when the conductive film is exposed to light, thereby achieving a heating effect on the surface of the photovoltaic module.

[0015] S8 establishes a control connection between the conductive membrane and a pressure sensor or vision inspection system. This step controls the opening and closing of the conductive membrane through the pressure sensor or vision inspection system, thereby achieving the control effect of the heating membrane and enabling the heating membrane to be activated when there is snow accumulation.

[0016] By adopting the above technical solution, this solution enables photovoltaic modules to adapt to snowy environments and operate stably in snowy environments by adding a heating structure to the surface of traditional photovoltaic modules.

[0017] Preferably, in step S1, the photovoltaic module is dusted by a dust-collecting structure to avoid uneven adhesion of the full-color microfilm due to dust, while ensuring close contact between the full-color microfilm and the surface of the photovoltaic module.

[0018] By adopting the above technical solution, this solution can adjust the visible light spectrum through a full-color micro-layer film, thereby making the frequency of natural light spectrum more concentrated and facilitating the light collection and conversion of photovoltaic modules.

[0019] Preferably, in step S2, the full-color micro-coating film is laminated using a pressing roller. The pressing roller can uniformly squeeze the full-color micro-coating film, thereby reducing the local pressure on the surface of the photovoltaic module during the lamination 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-coating film can prevent the deformation of the prism structure inside the full-color micro-coating 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 to adhere the fibers as they pass over the surface of the conductive film, thereby creating a velvety effect. At the same time, the velvety surface can protect the surface of the conductive film.

[0022] By adopting the above technical solution, this solution produces a velvety surface effect through adhesion, which can reduce the risk of the velvety structure falling off the surface of the conductive film.

[0023] Preferably, in step S5, the uniform heating of the semiconductor heating film under energized conditions enables the conductive film to control the heating film and achieve the effect of melting snow. The use of a grid-type semiconductor heating film structure can ensure the effect of melting snow while avoiding any impact on the light-gathering efficiency of the photovoltaic module.

[0024] By adopting the above technical solution, this solution can reduce the thickness and weight of the heating film through semiconductor heating, thereby avoiding the impact of this method on traditional photovoltaic modules.

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

[0026] By adopting the above technical solution, this solution controls whether the heating film works through pressure sensing, avoiding manual operation and control, thereby reducing the manual maintenance cost of this device.

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

[0028] This method overcomes the problem of photovoltaic modules failing to function in snowy environments. By combining a conductive film and a heating film, this method is completely independent of existing photovoltaic module structures, reducing the difficulty of assembly and installation while ensuring effective compatibility with various photovoltaic module structures. Control and adjustment are achieved through structures such as pressure sensors, thus avoiding problems such as damage to the heating film caused by prolonged continuous heating. At the same time, this method improves the photovoltaic module without affecting its original light-receiving area. Furthermore, by laminating a full-color micro-layer film, it ensures that the photovoltaic module can stably receive light from various visible light spectra. Attached Figure Description
