Organic semiconductors with polar side groups are capable of mixed electronic and ionic conduction, making them candidates for electrodes in electrochemical devices. In the case of conjugated polymers, electrochemical and redox properties can be tuned through choice of polymer backbone and side chain [1, 2]. Conjugated polymer electrodes can show excellent charging and discharging rates, high coulometric efficiency, efficient charge transport and reversible charging in simple aqueous electrolytes, making them interesting for different applications including energy storage. However, the specific capacity and operational stability need to be improved [3]. We use molecular modelling together with electrochemical measurements to investigate the relationship between polymer chemical structure and the redox properties, charging behaviour and cycling stability of the polymer electrodes. We use molecular dynamics simulations to explore how the side chain structure influences polymer packing, film swelling and stability [4]; how structure influences polymer-ion interactions; and how these interactions influence electronic transport properties. Finally, we use simulations to explore how chemical structure influences specific capacity. The findings can help to develop chemical designs for improved conjugated polymer electrodes for aqueous environments.

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.
