Organic-inorganic perovskite based solar cell

摘要

The present invention provides a solid state solar cell comprising a transparent conducting support layer, on which a nanostructured, surface-increasing, mesoporous scaffold structure is provided, wherein an organic-inorganic perovskite layer is provided on said scaffold structure, and wherein a counter electrode is provided in electric contact with said perovskite layer. The mesoporous scaffold preferably comprises a doped semiconductor material, in particular doped TiO
