Hybrid organic-inorganic perovskite-based solar cell with copper oxide as a hole transport material

A hybrid organic-inorganic perovskite-based solar cell with copper oxide as a hole transport material, comprising:

• a glass substrate;
• a transparent conducting film layer formed on the glass substrate;
• a layer of electron transport material formed on the transparent conducting film layer such that the transparent conducting film layer is sandwiched between the glass substrate and the layer of electron transport material;
• a light absorber layer formed on the electron transport material layer, the layer of electron transport material being sandwiched between the light absorber layer and the transparent conducting film layer;
• a layer of hole transport material formed on the light absorber layer, the hole transport material including copper oxide, the light absorber layer being sandwiched between the layer of hole transport material and the layer of electron transport material;
• and
• a conductive metallic contact formed on the layer of hole transport material, the layer of hole transport material being positioned between the conductive metallic contact and the light absorber layer.
