Solid state ionic (SSI) devices such as fuel cells, electrolyzers, batteries and sensors are becoming critically important in our effort to promote clean and renewable energy and decarbonize the future, due to their distinct advantages in efficiency and scalability over conventional conversion and storage technologies. Fast-ion conductors (FICs) are an indispensable component in SSI devices. The ionic conductivity of FICs plays a pivotal role in the performance of these devices. Known for their abundant, versatile defects and ion-transport-friendly environment, cubic perovskites have been enthusiastically explored in the past few decades as a promising class of FICs. In this presentation, we will first review recent advances in perovskite FICs. By combining theory and experiment, we will then discuss the interplay between defect-chemistry, ionic transport, and electrochemical stability using several cubic perovskite FICs, old and new, as illustrating examples. We will also highlight several useful experimental techniques to characterize ionic conductivity, transport number and electrochemical stability of FICs. We will finally provide our thoughts on potential applications of these perovskite FICs to generate new interest in developing innovative FICs and SSI devices.
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.
