Abstract

The invention belongs to the field of solar cells, particularly relates to LOW-E glass curtain wall color imitated front plate glass for a photovoltaic module, and further discloses the photovoltaic module prepared from the LOW-E glass curtain wall color imitated front plate glass. The invention discloses the LOW-E glass curtain wall color imitated front plate glass, high-refractive-index layers and low-refractive-index layers which are alternately stacked are formed by depositing materials with different refractive indexes, a dielectric film block with the required imitated LOW-E glass curtain wall color is formed by adjusting the thickness matching among all the layers, and the LOW-E glass curtain wall color imitated front plate glass capable of being used for the photovoltaic module isformed by depositing the dielectric film block on the surface of the glass substrate. The front plate glass has high transmittance and good weather resistance and water resistance in a sunlight waveband range; the photovoltaic module has excellent color 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 the photovoltaic building integration for the appearance color can be met.

Description

technical field [0001] The invention belongs to the field of solar cells, and in particular relates to a front plate glass for a photovoltaic module with a color imitating a LOW-E glass curtain wall, and further discloses a photovoltaic module with a color imitating a LOW-E glass curtain wall prepared therefrom. 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 inexhaustibl...
