Abstract

This work reports the development of hybrid devices composed of organic and inorganic thin films, deposited on fluorine doped tin oxide coated glass substrates (FTO). The organic layers, graphene oxide (GO) and poly (ethylenimine) (PEI) were deposited by the layer by layer technique (LbL), through the aerosol spray variant. The inorganic layer, titanium dioxide (TiO2), was deposited by sputtering and the aluminium electrode by thermal evaporation. To characterize these devices was used UV-Visible spectrophotometry to observe the films growth and optical microscopy to analyze the surface morphology. Finally, the electrical measurements were performed by measuring the I-V characteristic curves. The final device (FTO/PEI/GO/ TiO2/Al)20 showed a significant change in the behaviour when interacting with light.
