NOVELTY - A transparent conductive thin film is formed on glass surface and excess transparent conductive film is etched away, to obtain target pattern. A metal oxide dense layer is formed on target pattern. Then, titania slurry is coated on a titania electrode, to obtain porous titania thin layer. A layer is formed on porous titania thin layer and baked, to obtain perovskite material/porous material hybrid structure. Hole-conductive layer and layer of gold or silver are formed on surface of resultant product, to obtain all-solid organic-inorganic hybrid perovskite solar cell.    USE - Preparation of all-solid organic-inorganic hybrid perovskite solar cell (claimed).    ADVANTAGE - The method enables simple mass-production of all-solid organic-inorganic hybrid perovskite solar cell having high efficiency, excellent stability and substrate adaptability, and increased spectral response range, with high repeatability.    DETAILED DESCRIPTION - A transparent conductive thin film is formed on glass or quartz glass surface using magnetron sputtering, to obtain transparent conductive substrate. Excess transparent conductive film on transparent conductive substrate is etched away by chemical etching method, to obtain target pattern. A metal oxide dense layer is formed in a region of target pattern using magnetron sputtering method. Then, a titania electrode is placed in aqueous solution of titanium tetrachloride at 70 degrees C for 30 minutes, rinsed with deionized water and ethanol, dried, titania slurry is coated on the surface of titania electrode by spin coating and heated in a muffle furnace at 500 degrees C for 20-40 minutes, to obtain porous titania thin layer. A layer is formed on porous titania thin layer or metal oxide dense layer by spin-coating organic-inorganic perovskite material precursor solution and baked at 100 degrees C for 30 minutes, to obtain perovskite material/porous material hybrid structure or perovskite material/metal oxide structure. A solution containing hole-conductive material is spin-coated surface of the resultant structure, to obtain hole-conductive layer. A layer of gold or silver is formed on surface of resultant product by vacuum evaporation method, to obtain all-solid organic-inorganic hybrid perovskite solar cell having porous structure or planar structure. The metal oxide includes titania and zinc oxide. The thickness of metal oxide dense layer is 50-100 nm.
