Abstract

The invention belongs to the field of solar cells, particularly relates to yellow front plate glass for a photovoltaic module, and further discloses a yellow photovoltaic module prepared from the yellow front plate glass. According to the yellow front plate glass disclosed by the invention, high-refractive-index layers and low-refractive-index layers which are alternately superposed are formed bydepositing materials with different refractive indexes, a required yellow dielectric film block is formed by adjusting the thickness matching among the layers, and the yellow front plate glass capableof being used for the photovoltaic module is formed by depositing the yellow dielectric film block on the surface of the glass substrate. The yellow front plate glass has high transmittance and goodweather resistance and water resistance in a sunlight waveband range; the yellow front plate glass has excellent color uniformity in an angle range with a reflection angle not greater than 60 degreesand has color saturation higher than 20 at a near-normal reflection angle, the appearance effect of the photovoltaic module can be effectively improved, the problem of single color of a traditional photovoltaic module is effectively improved, and the requirement of photovoltaic building integration for appearance color can be met.

Description

technical field [0001] The invention belongs to the field of solar cells, in particular to a yellow front plate glass for a photovoltaic module, and further discloses a yellow photovoltaic module 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.
