Description

technical field [0001] The invention relates to a solar battery backplane film, in particular to a graphene solar battery backplane film and a preparation method thereof. Background technique [0002] As a clean, pollution-free and inexhaustible energy source, solar energy has attracted widespread attention. Solar cells are effective tools for converting solar energy directly into electrical energy. Since solar cells need to be corroded by natural factors such as rainwater and ultraviolet rays outdoors for a long time, it is very unfavorable to the service life of the solar cells. Therefore, how to improve the oxidation resistance and corrosion resistance of the solar cell backsheet, and prolong the service life of the solar cell backsheet is the focus of current research. Contents of the invention [0003] Technical issues solved: [0004] In order to obtain a solar battery backplane film material with strong oxidation resistance and high corrosion resistance and prolo...
