Abstract

The invention belongs to the field of solar cells, particularly relates to green front plate glass for a photovoltaic module, and further discloses a green photovoltaic module prepared from the greenfront plate glass. According to the green front plate glass disclosed by the invention, high-refractive-index layers and low-refractive-index layers which are alternately superposed are formed by depositing materials with different refractive indexes, a required green dielectric film block is formed by adjusting the thickness matching among the layers, and the green front plate glass capable of being used for a photovoltaic module is formed by depositing the green dielectric film block on the surface of a glass substrate. The green 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 greater than 60 degrees and 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 the single color of a traditional photovoltaic module is effectively improved, and the requirement of the photovoltaic building integration for an appearance color can be met.

Description

technical field [0001] The invention belongs to the field of solar cells, in particular to a green front plate glass for a photovoltaic module, and further discloses a green 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. [0003] Building Integrated Photovoltaic (BIPV, Building Integrated PV, PV stands ...
