NOVELTY - The plate has a substrate layer (1) formed with a carbon layer (3) and a sol-gel layer (2). The carbon layer is coated with a black coating that comprises a raw material composition of 10 pts.wt resin, 20 pts.wt modified resin, 60 pts.wt curing agent, 5-40 pts.wt radiating filler, 0.5 pts.wt black filler and 50-500 pts.wt solvent. The radiating filler is formed of oxygen, berkelium oxide, boron oxide, titanium oxide, silicon carbide, silicon nitride, boron nitride, silicon nitride and gallium nitride.    USE - High-efficient black solar energy battery rear plate.    ADVANTAGE - The plate has better water-proof effect, high production quality and high production efficiency.    DETAILED DESCRIPTION - The resin is formed of polyvinyl fluoride, polyvinylidene fluoride, PTFE, fluorinated ethylene propylene, vinyl fluoride-vinyl ether copolymer, vinyl chloride-ethylene copolymer, chlorotrifluoroethylene, alkyl vinyl ester copolymer and tetrafluoroethylene-vinyl ester copolymer. The modified resin is formed of methacrylic acid methyl ester, methacrylate, acrylic acid ethyl ester and pentaerythritol ester of butanediol. The radiating filler is formed of oxygen, berkelium oxide, boron oxide, titanium oxide, silicon carbide, silicon nitride, boron nitride, silicon nitride and gallium nitride. The black filler is formed of titanium black, iron manganese black, copper chromium black and carbon black. The curing agent is selected from one of epoxy resin curing agent, amine curing agent, anhydride curing agent and curing agent of one of isocyanate, acetone, toluene, xylene, ethyl acetate, propyl acetate, butyl acetate, ethyl butyrate, propylene glycol methyl ether acetate and methyl pyrrolidone. An INDEPENDENT CLAIM is also included for a high-efficient black solar energy battery rear plate preparation method.    DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a high-efficient black solar energy battery rear plate.    Substrate layer (1)    Sol-gel layer (2)    Carbon layer (3)
