The method includes steps of: obtaining a substrate roll; unwinding the substrate roll to unroll the substrate roll to form a substrate assembly (), the substrate assembly () having a first-ring exposed segment (), a middle-ring covered segment () and a tail-ring exposed segment () which are sequentially connected; and performing a slurry pulling treatment on the substrate assembly () to form a first active layer () and a second active layer () that are formed together on two opposite side faces of the substrate assembly (), the first active layer () being attached to the first-ring exposed segment () and the middle-ring covered segment (), and the second active layer () being attached to the middle-ring covered segment () and the tail-ring exposed segment ().",
