[0046] The aluminum-like plate front plate glass described in this embodiment includes a glass substrate and a 5-layer structurally designed aluminum-like plate dielectric film block, and the specific structure is designed as: air / / glass substrate / / high refractive index material H / / low refractive index material L / / High refractive index material H / / Low refractive index material L / / High refractive index material H / / Organic polymer, specifically including interval settings:

[0047] The first functional layer (H): made of high refractive index material TiO 2 (n at 550nm H =2.32) the high refractive index layer H formed has a thickness of 130nm;

[0048] The second functional layer (L): that is, made of low refractive index material SiO 2 (n at 550nm L =1.45) formed low refractive index layer L, the thickness is 45nm;

[0049] The third functional layer (H): that is, made of high refractive index material TiO 2 (n at 550nm H =2.32) formed high refractive index layer H, the ...

Embodiment 2

[0065] The aluminum-like plate front plate glass in this embodiment includes a glass substrate and a 7-layer structurally designed aluminum-like plate dielectric film block, and the specific structure is designed as: air / / glass substrate / / high refractive index material H / / low refractive index material L / / High Refractive Index Material H / / Low Refractive Index Material L / / High Refractive Index Material H / / Low Refractive Index Material L / / High Refractive Index Material H / / Organic polymer, specifically including interval settings:

[0066] The first functional layer (H): made of high refractive index material TiO 2 (n at 550nm H =2.32) formed high refractive index layer H, the thickness is 35nm;

[0067] The second functional layer (L): that is, made of low refractive index material SiO 2 (n at 550nm L =1.45) formed low refractive index layer L, the thickness is 20nm;

[0068] The third functional layer (H): that is, made of high refractive index material TiO 2 (n at 550nm ...

experiment example

[0088] The properties of the front glass of the imitation aluminum plate prepared in the above-mentioned Examples 1-2 were respectively tested, including light transmittance and color saturation. The specific test results are shown in Table 1.

[0089] Table 1 Performance test results of the front glass of the imitation aluminum plate

[0090] Light transmittance / % (sunlight band) color saturation Example 1 80.2 0 Example 2 80.7 0

[0091] As can be seen from the data in Table 1, the average transmittance of the aluminum-like plate front plate glass prepared in Example 1-2 in the solar light band range is 80.2% and 80.7%, both greater than 80%, with higher light transmittance. Transparency can effectively reduce the power loss of components; since the imitation aluminum plate is neutral color, the color saturation of the test is 0, and the required color can be achieved very well.

[0092] Table 2-3 shows the test results of the color uniformit...

Abstract

The invention belongs to the field of solar cells, particularly relates to imitated aluminum plate front plate glass for a photovoltaic module, and further discloses an imitated aluminum plate photovoltaic module prepared from the imitated aluminum plate front plate glass. According to the imitated aluminum plate front plate glass, high-refractive-index layers and low-refractive-index layers whichare alternately stacked are formed by depositing materials with different refractive indexes, a needed dielectric film block of the imitated aluminum plate is formed by adjusting the thickness matching among the layers, and the imitated aluminum plate front plate glass capable of being used for the photovoltaic module is formed by depositing the dielectric film block on the surface of the glass substrate. The imitated aluminum plate front plate glass has high transmittance and good weather resistance and water resistance in a sunlight waveband range; the imitated aluminum plate has excellentcolor uniformity in an angle range with a reflection angle not larger than 60 degrees, the appearance effect of the photovoltaic module can be effectively improved, the problem that a traditional photovoltaic module is single in color is effectively solved, and the requirement of photovoltaic building integration for the appearance color can be met.

Description

technical field [0001] The invention belongs to the field of solar cells, in particular to an aluminum-imitated front plate glass for a photovoltaic component, and further discloses a photovoltaic component with the color and texture of an imitated aluminum plate prepared by the same. Background technique [0002] With the rapid development of the economy, the demand for energy is getting stronger and stronger. Due to the use of traditional coal, oil, natural gas and other fossil fuels, a large amount of toxic and harmful substances will be discharged, which will cause serious pollution to water, soil and the atmosphere, and even form the greenhouse effect and acid rain, seriously endangering the living environment and health of human beings. , therefore, renewable clean energy has received more and more attention. Solar energy has become a key development direction in the current energy field because of its clean, pollution-free and inexhaustible advantages. [0003] Buil...
