▎ 摘　　要

NOVELTY - The manufacturing method involves preparing a graphene layer that is disposed on a first substrate which comprises a metal or alloy selected from the group consisting of nickel, cobalt, iron, platinum, gold, ruthenium, iridium, and aluminum. A metal layer is applied to the graphene layer to form a metalized graphene layer. The metalized graphene layer is exfoliated from the first substrate. The metalized graphene layer is laminated to a second substrate. USE - Manufacturing method of graphene layer on substrate used in manufacturing of e.g., solar cells and organic light emitting diodes (OLED). ADVANTAGE - The manufacturing method uses copper foil which is very low cost, flexibility and easy to handle, in which the graphene is deposited. The growth of graphene layer on the metal foil is accomplished using the chemical vapor deposition (CVD) which enables relatively large-scale production of monolayer graphene. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a method of making solar cells or organic light emitting diodes (OLED); and (2) a method of transferring a graphene layer to a flexible substrate. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic flow diagram of the metal-assisted exfoliation process for large-area transfer of single-layer graphene from catalytic copper substrates to flexible sheets.
