  • Patent number: 12389711
    Abstract: Provided are a solar cell metal electrode and a preparation method therefor, and a mask. The preparation method for a solar cell metal electrode in the present invention comprises: laser-etching a polymer film according to a desired electrode shape to prepare a mask; and fixing the mask onto a substrate, and plating the mask with a metal film by using a physical vapor deposition method, so that a metal electrode or an electrode seed layer in the desired shape grows on the substrate. According to the method of the present invention, the preparation cost is low, the conductivity of an electrode prepared is high, the light shielding area is small, and the photoelectric conversion rate is high.
