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.
