In this research, we address the critical challenge of fabricating a thin and dense Gd-doped ceria (GDC) buffer layer to impede interfacial elemental diffusion between the yttrium-doped zirconia electrolyte and the perovskite functional cathode within metal supported solid oxide fuel cell (MS-SOFC). To overcome the limitations of conventional sintering processes (>1400 ºC), we successfully synthesized GDC particles with a precise size of 3 nm using a novel precipitation method. The subsequent application of a spin-coating process enabled the formation of a thin (<1 μm) buffer layer at temperatures below 1000 ºC. Microstructure analysis at varying temperatures confirmed the efficacy of the synthesized buffer layers. These advancements were applied to a cutting-edge MS-SOFC, manufactured through co-firing in a reducing atmosphere. Electrochemical investigations, employing 2-probe AC impedance and DC measurements, highlighted the superior performance achieved through the optimization of microstructure in each layer and the incorporation of a thin ceria-blocking layer. This study presents a groundbreaking approach to enhance the efficiency and feasibility of MS-SOFC, emphasizing the significance of dense GDC buffer layer at low temperature and its application in next-generation metal-supported fuel cell technologies.

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.
