  Internship for 6 months: Graphene-based materials deposited by "Electrospray": applications to the electrodes of organic solar cells. Summary: The objective of this work is to develop graphene-based films for applications dedicated to photovoltaic devices (organic solar cells). Thin films of graphene oxide (GO) were deposited by the Electro-spray technique on glass substrates using a solution synthesized from the graphite powder. Heat treatment was applied to a number of samples in an attempt to reduce graphene oxide (RGO) and to get close to the electrical properties of pure graphene. Structural and morphological analyzes, which were performed using Raman spectroscopy and scanning electron microscopy (SEM), confirmed that the GO thin films were obtained. These analyzes allowed us to highlight the reduction in the size of GO films and the improvement in surface morphology. This was done following vacuum annealing. The first results of electrical and optical characterizations have highlighted encouraging results. Optical characterizations (measurement of transmission) have shown that GO and RGO films can achieve high and stable transmittance values ​​in the visible range (around 90%). The study of the electrical characteristic (I (V)) has shown that the application of a heat treatment (vacuum annealing) and therefore the reduction of the GO films, significantly improves the resistivity / conductivity of the films (low resistivity ~ 0.015 Ω.m).
