▎ 摘　　要

NOVELTY - Backsheet comprises a heat dissipation layer (2) comprising graphene and carbon nanotubes. A protective layer (4) formed on one surface of the heat dissipation layer and an adhesive layer (3) for attaching the heat dissipation layer and the protective layer. USE - The backsheet is useful for solar cell module. ADVANTAGE - The backsheet has improved heat dissipation efficiency. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view showing the structure of a back sheet for a solar cell module. Heat dissipation layer (2) Adhesive layer (3) Protective layer (4)
