One of the promising technologies for future alternative energy sources is the direct conversion of sunlight into chemical and electrical energy by using artificial photosynthesis. Artificial photosynthesis has attracted great interest over the last decades, especially for its potential to produce clean and cheap renewable energy without dependence on fossil fuels and without carbon dioxide emission. Artificial photosynthesis applications span from many fields such as: solar fuel production, water splitting, photo-degradation of pollutants, and catalysis of other chemical reactions, e.g. for the production of fine chemicals. An important challenge in artificial photosynthesis is the development of stable and inexpensive catalysts that can harvest the visible light in solar spectrum. Although the great progress in this field over the last years, the energy conversion efficiency of artificial photosynthesis remained low. Therefore, new approaches and new materials as photocatalysts and photoelectrocatalysts should be introduced for the improvements of artificial photosynthesis conversion efficiencies. While most of the research in this field is focused on metal based semiconductors (metal oxides, sulfides and nitrides) as photo (electro)catalysts, in the last years metal-free graphitic carbon nitride (g-CN) materials have attracted widespread attention due to their (electro)catalytic and photocatalytic activity alongside their low price and simple synthesis. In this talk I will show our recent progress in carbon nitride synthesis by using supramolecular chemistry to synthesize well-defined structures of g-CN such as hollow boxes, spheres, tubes and spherical macroscopic assemblies with the possibility to control their photophysical and photocatalytic properties. I will demonstrate in particular their operation as promising materials for artificial photosynthesis and other photoelectronic applications. I will introduce new approaches to grow g-CN layers with altered properties on conductive substrates for photoelectrochemical application. The growth mechanism of g-CN on flat and porous substrates as well as their chemical, photophysical, electronic and charge transfer properties will be discussed
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.
