Abstract: The present invention relates to a method for producing a solid solar cells, including the steps of providing a hole collector layer, applying a conductive layer onto the hole collector layer, applying an electron blocking layer onto the conductive layer, applying a sensitizer layer onto the electron blocking layer, applying a hole blocking layer onto the sensitizer layer, and providing a current collector and/or a metal layer or a conductor. The sensitizer layer including an organic-inorganic perovskite is applied by co-deposition of one or more sublimated divalent or trivalent salts and of one or more sublimated organic ammonium salts to obtain the organic-inorganic perovskite. The invention also relates to solid state solar cells, wherein the charge flow is inverted compared to the charge flow in a solar cell of conventional architecture and/or obtained by the above method.

Abstract: The present invention relates to charge injection from metallic conductors to semiconductor or insulation materials based on organic or inorganic molecules and macromolecules with electrical or optical properties, and specifically to a new charge injection layer for electro-optical devices comprising a polymer with conjugated units and a salt mixed with the aforementioned polymer, characterized in that the oxidation state of the polymer is not modified when it is mixed with the salt. Despite the fact that there is no change in the oxidation state of the polymer, the polymer and salt mixture according to the invention makes it possible for a high enough number of charges to reach the optically active layer, such that the efficiency in the charge injection process is increased up to levels exceeding even those provided by the standard PEDOT.
