Operando X-ray diffraction (XRD) experiments have become a powerful and widely adopted technique for tracking internal processes during battery cycling. They provide critical insights into fundamental electrochemical redox mechanisms and aging phenomena in battery materials. However, obtaining high-quality, representative and actionable data from operando measurements requires careful control of numerous experimental parameters (including cell configuration, electrode preparation, goniometer geometry, data acquisition protocols and dose).1,2
In this presentation, we will explore key factors that determine the success of operando synchrotron experiments, such as cell design, experimental setup and sample preparation. These concepts will be illustrated through case studies demonstrating how operando XRD can reveal the electrochemical signatures of diverse battery materials.
At the same time, the vast amount of diffraction data generated by high-throughput screening and operando studies at large-scale facilities demands advanced software solutions capable of real-time analysis, moving beyond traditional post-experiment pattern-by-pattern workflows. To address this need, we will introduce FullProfAPP, a software platform built on the foundations of the FullProf program, designed to process, refine, and visualize large collections of powder diffraction patterns efficiently.3
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.
