Abstract
The invention discloses a method using a preservative film to transfer a conductive film. A layer of a first alcohol solvent covers a clean substrate, and a preservative film is extended on the substrate. After the first alcohol solvent volatilizes completely, the preservative film is coated with a layer of water-soluble conductive material to obtain a conductive film, which is left until the conductive film is dry in case water in the conductive film influences lower-layer material on a target substrate. The conductive film is wetted with a second alcohol solvent to drive the conductive film to separate from the preservative film. When an edge of the conductive film can be separated from the preservative film, the preservative film and the conductive film are peeled from the substrate together. The preservative film covered by the conductive film is spread on the target substrate so that the conductive film is closely attached to the surface of the target substrate. The preservative film in the upper layer is peeled off, and the conductive film is transferred to the target substrate. With the method, a streamline production mode is easy to form; resources are saved; the cost is low; and the transferred conductive film is better in conductivity and can improve the photoelectric conversion efficiency of a solar cell.
