NOVELTY - The battery has an organic N-type receptor material layer arranged with an ultra-thin metal net-like structure layer and a thin metal net-like structure layer. An electronic donor material layer is arranged with the receptor material layer to form dual internal electric field to improve electronic-type material and hole-type material diffusing process. A cavity transmission layer is made of organic conductive polymer film e.g. poly (3, 4 thiophene), polystyrene sulfonate and polyaniline organic conductive polymer film, or metal oxide film e.g. silicon oxide film or nickel oxide thin film.    USE - Nested metal embedded hetero-junction organic solar battery.    ADVANTAGE - The electronic donor material layer is arranged with the N-type receptor material layer to form the dual internal electric field so as to improve the electronic-type material and hole-type material diffusing process, thus increasing thickness of hetero-junction structure and improving separation efficiency of photo-generated electron and conversion efficiency of the battery.    DETAILED DESCRIPTION - The battery is provided with an electronic buffer layer, a metal organic coordination compound material layer, a transparent anode electrode, a phenanthroline compound material layer, an oxadiazole compound material, an imidazole compound material, a pyridine compound material, a transparent substrate and a transparent cathode electrode. The transparent substrate is made of glass, flexible substrate, metal sheet or metal foil. The transparent cathode electrode is made of alloy of lithium, magnesium, calcium, strontium, aluminum or indium. The electronic buffer layer is made of metal organic material e.g. pyridine, phenanthroline, oxadiazole or imidazole compound material. The metal organic coordination compound layer is made of 8-hydroxyquinoline aluminum or two (2-methyl-8-quinoline-4-phenylphenol) aluminum. The pyridine compound material is made of tri (2, 4, 6-trimethyl-3-(3-yl) phenyl) borane. The phenanthroline compound material layer is made of 2, 9, 4, 7 -1, 10 second phenanthrene or 4, 7-1, 10 second phenanthrene. The oxadiazole compound material is made of 2 - (4) -5- (4-tertbutyl phenyl) -1, 3, 4-or 1, 3-two (4-tertiary aminetert-butylphenyl-1, 3, 4-diazo-5-yl amino) benzene. The imidazole compound material is made of 1, 3, 5-tri (N-phenyl-benzimidazole-2) benzene. The transparent anode electrode is made of indium tin oxide. An INDEPENDENT CLAIM is also included for a nested metal embedded hetero-junction organic solar battery preparation method.
