A solar cell device comprises an anode, a hole buffer layer, a first active layer, an interlayer, a second active layer, an electronic buffer layer and a cathode which are laminated sequentially. The first active layer and the second active layer are made of mixture of poly 3-hexylthiophene and 6,6-phenyl-C61-butyric acid methyl ester, the interlayer comprises a fullerene derivative layer, a lithium salt layer laminated on the surface of the fullerene derivative layer and a doped layer laminated on the surface of the lithium salt layer, the fullerene derivative layer is made of materials selected from at least one of footballene, carbon 70, the (6,6)-phenyl-C61-butyric acid methyl ester and (6,6)-phenyl-C71-butyric acid methyl ester, the lithium salt layer is made of materials selected from at least one of lithium carbonate, lithium fluoride and lithium oxide, and the doped layer is made of materials including phthalocyanine compounds and hole-transporting materials doped in the phthalocyanine compounds. The solar cell device is high in energy conversion efficiency. Besides, the invention further provides a production method of the solar cell device. |
