Summary:The utility model discloses a graphene nanocrystalline silicon solar cell, which is characterized in that the structure of the graphene nanocrystalline silicon solar cell is sequentially formed by a metal upper electrode, wide-band-gap n-type graphene, wide-band-gap p-type graphene, n-type nanocrystalline silicon film, p-type nanocrystalline silicon film, narrow-band-gap n-type graphene, narrow-band-gap p-type graphene and a metal lower electrode from top to bottom. The wide-band-gap n-type graphene and the wide-band-gap p-type graphene are used for absorbing sunlight of short-wave-band wavelength; the n-type nanocrystalline silicon film and the p-type nanocrystalline silicon film are used for absorbing sunlight of medium-wave-band wavelength; and the narrow-band-gap n-type graphene and the narrow-band-gap p-type graphene are used for absorbing sunlight of long-wave-band wavelength. The graphene nanocrystalline silicon solar cell has the advantages that the graphene and nanocrystalline silicon film with diffe
