Lately, Graphene has emerged as an option material with a lot of interest in the scientific community due to its exceptional electric, thermal and mechanical properties. This carbon allotrope is as thick as a single carbon atom and could improve the conductive properties of a simple conductive host film by the correct incorporation of the particles on its matrix. In this paper, we present the results of the synthesis of polythiophene/graphene composite by means of electrochemical route. The first step was the top-down chemical synthesis of graphene oxide (GO) with graphite as starting material. The second step was the polythiophene synthesis using electrochemical methods to obtain the polymer, using as working electrode a glass substrate covered with ITO (indium-tin-oxide). The films were prepared with polythiophene (PTh) and graphene oxide (GO), the GO present in the film was then reduced to mainly have graphene (G) present. The results were analyzed to check the film growth and characteristics with profilometry and infrared spectroscopy, Field-Emission Scanning Electronic Microscopy (FESEM) --and electrochemical methods known as Cyclic voltammetry and Chronoamperometry. The XRD results shown the obtention of reduced oxide graphene, and the FESEM allows to observe the films of the composite obtained, by means of the voltmammetry and chronoamperometry was possible to induce the electrochemical phenomena involved

nanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009. Our worldwide conferences cover cutting-edge materials topics like perovskite solar cells, photovoltaics, optoelectronics, solar fuel conversion, surface science, catalysis and two-dimensional materials, among many others.
Previously nanoGe Spring Meeting (NSM) and nanoGe Fall Meeting (NFM), MATSUS is a multiple symposia conference focused on a broad set of topics of advanced materials preparation, their fundamental properties, and their applications, in fields such as renewable energy, photovoltaics, lighting, semiconductor quantum dots, 2-D materials synthesis, charge carriers dynamics, microscopy and spectroscopy semiconductors fundamentals, etc.
International Conference on Hybrid and Organic Photovoltaics
International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.
Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics
The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
The International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics (NIPHO) is the best place to hear the latest developments in perovskite solar cells as well as on recent advances in the fields of perovskite light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
