Summary

The purpose of the presented extension project originates from the interest in the development of an alternative, modern and sustainable study technique regarding photovoltaic cells, as clean energy sources and low monetary cost are considered of great importance to social-environmental concerns. Aiming at a future in the experimental area, the student intends that the project itself will enable her to understand and deepen her knowledge about the production of research tools, based on the characterization of using a pure carbon-based platform, in order to establish sustainable practices and economics in other technological areas. The work's aim is the development of a photovoltaic device based on a carbon platform, which begins with the study of the synthesis, deposition and characterisation of the optical and electrical properties known as rGO (reduced graphene oxide) alongside poly(3-hexylthiophene) (P3HT). Whereas they are soluble, conjugated polymers facilitate techniques such as spin-coating in the deposition of FTO substrates. The blend of the polymeric films was analyzed by optical absorption in the spectral range of ultraviolet-visible (UV-Vis) and photoluminescence (PL) and emission ellipsometry (EE) in a function of sample temperature. The surface morphology of the films was studied by atomic force microscopy (AFM). Such techniques are considered low cost and production simplicity. We noted that the bandgap of the blend of P3HT and RGO is smaller than the other systems. We observed a high degree of polarized emission of the P3HT films which varies subtly according to the temperature. For blends with RGO, the polarization degree in the emission decreases and the roughness on the surface increases. As a result, the RGO improves the energy transfer between adjacent polymer chains at the cost of greater surface roughness. All these processes were carried out in laboratories of the Physics Institute of the Federal University of Mato Grosso, Cuiabá campus.
