▎ 摘　　要

NOVELTY - The backboard has a high heat conducting base material layer provided with carbon nanotubes and/or graphene and a thermally conductive filler. The thermally conductive filler is provided with barium carbonate, barium sulfate, boron nitride, alumina, magnesium oxide, Silicon Nitride, aluminum nitride or silicon carbide. A master-batch is polyethylene terephthalate, Polypropylene and Polyethylene. A toughening agent is Sodium hydrogen sulfite or Styrene Ethylene Butylene Styrene. The high heat- conducting substrate layer is provided with a master batch. USE - High heat conducting film solar battery backboard. ADVANTAGE - The backboard has high thermal conductivity, and accelerates heat transfer speed and reduces working temperature of substrate and assembly working temperature and solar assembly cost, increases output power of photovoltaic component up-to 1-2 %. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a high heat conducting solar battery backboard manufacturing method. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a high heat conducting film solar battery backboard.
