Description

technical field

[0001] The invention relates to the technical field of solar photovoltaic cells, in particular to a solar cell backboard and a preparation method thereof. Background technique

[0002] As a green and inexhaustible energy source, solar energy is undoubtedly the best choice to replace traditional thermal power generation. Since solar cells need to be exposed to outdoors for a long time, the cells in photovoltaic modules must be protected to prevent the influence and erosion of environmental factors such as water vapor, oxygen, and ultraviolet rays in the atmosphere. The solar backsheet is one of the accessories of the whole solar cell. It mainly plays the role of mechanical support and protection of the cell from the penetration of environmental factors. Therefore, how to improve the weather resistance of the backsheet has always been the research focus of the industry.

[0003] Solar battery backplanes in the prior art mainly include the following types: [...
