Description

Technical Field

[0001] This invention belongs to the field of photovoltaic panel coating technology, and specifically relates to a coating that improves the power generation efficiency of photovoltaic panels. Background Technology

[0002] The photoelectric efficiency of solar photovoltaic panels is very low in actual operation, usually less than 20%. At present, the main research on how to improve their output efficiency is to optimize the installation method, optimize the supporting hardware facilities, develop new panel materials and improve the self-cleaning of panel coatings.

[0003] For solar photovoltaic (PV) panels, the absorption of light with wavelengths between 350nm and 1200nm is particularly important. Maintaining high light transmittance and minimizing reflection is crucial. One solution is surface roughening, but this method also leads to the adhesion of dust and organic impurities. Existing methods such as manual cleaning, robotic cleaning, and high-pressure water cleaning can quickly damage the light-transmitting coating on the surface of solar PV panels. To address these issues, applying a dust-proof and self-cleaning coating to the surface of PV panels has become the preferred method for preventing contamination.

[0004] Patent CN114231177A discloses a self-cleaning coating for solar photovoltaic panels and its preparation method. This photovoltaic panel coating is prepared by preparing nano-TiO2 / SiO2, grafting it with siloxane, and then cross-linking and curing it with fluorosilane-modified hydrogen-containing silicone oil to obtain a self-cleaning coating that achieves good hydrophobic and oleophobic properties and self-cleaning function. However, the nano-TiO2 in the prepared nano-TiO2 / SiO2 has very weak photocatalytic properties, resulting in poor self-cleaning effect of the coating. Summary of the Invention

[0005] The purpose of this invention is to provide a coating that improves the power generation efficiency of photovoltaic panels, thereby solving the problem in the background art where the poor photocatalytic properties of nano-TiO2 in the actual use of photovoltaic panels lead to poor self-cleaning effect of the coating, which in turn affects the power generation efficiency of the photovoltaic panels.

[0020] Further, in step (3), the ratio of the nano ZnO / TiO2 / SiO2 composite powder, the ethanol aqueous solution, and the vinyltrimethoxysilane is 10g:50mL:0.3g.

[0021] Furthermore, the volume fraction of the ethanol aqueous solution in step (3) is 70%.

[0022] Furthermore, the modified polyaniline includes the following preparation steps:

[0023] KH-570 was added to an aqueous ethanol solution to obtain a silane treatment solution. Polyaniline powder was then immersed in the silane treatment solution, sealed, and stirred periodically. After settling, the powder was washed, centrifuged, and the supernatant was poured off to obtain modified polyaniline.

[0024] Furthermore, the ratio of KH-570 to the aqueous ethanol solution is 2g:100mL.

[0025] Furthermore, the volume fraction of the ethanol-water solution is 75%.

[0027] Furthermore, the soaking is performed at room temperature for 3 hours.

[0028] Furthermore, the timed stirring is performed once every 30 minutes.

[0030] Furthermore, the fluorosilane-modified hydrogen-containing silicone oil includes the following preparation steps:

[0040] 2. The nano-ZnO in the nano-ZnO / TiO2 / SiO2 composite powder prepared by this invention has good thermal conductivity. When the nano-ZnO / TiO2 / SiO2 composite powder undergoes surface cross-linking activity modification, the nano-ZnO will be uniformly dispersed in the middle of the coating, thereby improving the thermal conductivity of the coating. In addition, the presence of modified polyaniline can further improve the thermal conductivity of the coating. The two form a thermally conductive network in the coating, enabling the photovoltaic panel to achieve rapid cooling, thereby improving the power generation efficiency of the photovoltaic panel.

[0041] 3. This invention modifies the surface of nano-ZnO / TiO2 / SiO2 composite powder by preparing modified nano-ZnO / TiO2 / SiO2 composite powder, and then highly crosslinks it with fluorosilane-modified hydrogen-containing silicone oil to form a rigid fluorosilane-modified hydrogen-containing silicone oil network structure, which significantly enhances its adhesion to the surface of solar photovoltaic panels and significantly enhances the coating strength.

[0077] Comparative Example 3

[0078] This embodiment provides a coating to improve the power generation efficiency of photovoltaic panels. The specific synthesis steps are as follows:

[0079] Compared with Example 5, based on Example 5, 10g of the modified polyaniline prepared in Example 3 was replaced with 10g of polyaniline, and the remaining raw materials and preparation steps were the same as in Example 5.

[0080] Comparative Example 4

[0083] The photocatalytic performance and thermal conductivity of the coatings for improving photovoltaic power generation efficiency obtained in Examples 5-7 and Comparative Examples 2-4 were tested.

[0084] The photocatalytic performance was tested by adding a 0.10% methyl orange aqueous solution to three different areas on the surface of the self-cleaning coating. The solution was then irradiated with a visible light source for 12 hours for photodegradation. The test droplets were then diluted and detected by a UV-Vis spectrophotometer. The photocatalytic degradation rate of methyl orange was calculated and the average value was taken.

[0085] The thermal conductivity of the coating was tested using a DRL-Ⅲ thermal conductivity meter manufactured by Xiangtan Xiangyi Instrument Co., Ltd., via the steady-state heat flow method. The results are shown in Table 1.

[0086] Table 1

[0087] Degradation rate (%) 90.5 90.6 90.8 85.3 90.5 85.1 Thermal conductivity (W / mK) 1.04 1.06 1.11 0.72 0.73 0.41

[0088] As can be seen from Table 1, the degradation rates of Examples 5-7 are all higher than 90.5%. Observing Comparative Examples 2-4, it can be seen that the combination of nano zinc oxide and nano titanium dioxide in the modified nano ZnO / TiO2 / SiO2 composite powder greatly improves the degradation rate of organic matter by the coating.

[0089] The thermal conductivity data from Examples 5-7 show that the cross-linked thermally conductive network formed by nano-zinc oxide and modified polyaniline in the modified nano-ZnO / TiO2 / SiO2 composite powder significantly improves the thermal conductivity of the coating. Comparative Example 2 reveals that when only modified nano-TiO2 / SiO2 composite powder is present, the lack of the thermally conductive portion of nano-ZnO results in poor thermal conductivity, leading to a decrease in the coating's thermal conductivity. Comparative Example 3 shows that adding polyaniline to improve thermal conductivity, instead of using cross-linkable modified polyaniline, also leads to a decrease in the coating's thermal conductivity. Comparative Example 4 shows that the coating prepared using the combination of modified nano-TiO2 / SiO2 composite powder and polyaniline has the worst thermal conductivity.
