The talk will give an overview of our recent activities about design and processing of polymeric mixed-ionic-electronic conductors for opto-electronic and switchable technologies making use of electrochemical doping of conducting polymers.
Starting from p-type doping of poly(3-hexylthiophene) (P3HT) films1 and their solid-state absorption and conductivity behavior, I will show our latest results on n-type doping of naphthalenebisimide-based copolymers (PNDI2OD-T2)2 and some of its derivatives3. It is interesting to note that our data clearly show bell-shaped conductivity profiles which are indicative of localized charges and redox polymer characteristics for the n-type materials.
Within the talk I will also introduce redox polymer materials based on triphenylamine (TPA) and carbazole (CBz) redox units.4 Both redox units can be irreversibly linked upon (electro)chemical oxidation leading to dimer redox species. In polymer films these dimers can act as crosslinkers, the number of redox units strongly influencing their charge transport behavior. Extending our strategy from 2D thin films to 3D architectures allows us to apply 3D digital light processing which enlarges our architectural design yielding redox-active chess pattern, dot arrays or even pyramids with distinct electrochromic properties.5
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.
