  • HYBRID ORGANIC-INORGANIC PEROVSKITE-BASED SOLAR CELL WITH COPPER OXIDE AS A HOLE TRANSPORT MATERIAL
    Publication number: 20170324053
    Abstract: The hybrid organic-inorganic perovskite-based solar cell with copper oxide as a hole transport material includes a transparent conducting film layer (12) sandwiched between a glass substrate (11) and a titanium dioxide layer (14). The transparent conducting film layer (12) can be fluorine-doped tin oxide. A lead methylammonium tri-iodide perovskite layer (16) is formed on the titanium dioxide layer (14), such that the titanium dioxide layer (14) is sandwiched between the lead methylammonium tri-iodide perovskite layer (16) and the transparent conducting film layer (12). A layer of copper oxide (Cu2O) (18), as a hole transport material, is formed on the lead methylammonium tri-iodide perovskite layer (16). The lead methylammonium tri-iodide perovskite layer (16) is sandwiched between the layer of hole transport material (18) and the titanium dioxide layer (14). A gold contact (20) is formed on the layer of hole transport material (18).
