Battery technology has become increasingly important in recent years due to the growing demand for portable electronic devices and electric vehicles, and to improve the performance and lifespan of batteries it is essential to understand the complex processes that occur during their operation. NOTOS is a beamline from ALBA Synchrotron Light Source devoted to X-ray Absorption Spectroscopy (XAS), X-Ray Diffraction (XRD) which has been designed to study the electronic structure and the short- and long-range order in a wide range of scientific disciplines: chemistry, catalysis/electrocatalysis, energy science, nanomaterials, condensed matter, and environmental science. The available energy range is now 4.5-30 keV and the photon source is a bending magnet, but it will be extended up to 35 keV thanks to a partial refurbishment of the optics and the change of the bending magnet with a SuperBend source in the framework of the ALBA-II upgrade. In addition to the capability to perform XAS and XRD investigations separately, the beamline allows quasi-simultaneous XAS-XRD experiments. Examples of XAS and XRD measurements on commercial electrodes (phospho-olivine LiFePO4 and NMC111) are presented showing the performances of the beamline in operando. Finally, as real research case, we discuss the structural stability of Bimetallic Cu-doped Gold Nanoclusters in electrochemical CO2 reduction.
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.
