The 22nd ISCST Symposium will feature keynote talks presented by distinguished researchers from academic, industrial, and national laboratories. Keynote talks will cover topics related to coating materials, process and technology for energy and sustainability applications. Sections below provide talk titles, abstracts, and information about each keynote speaker.
Title: “Sustainable Materials for Coatings”
YuanQiao Rao, Ph.D. Senior R&D Fellow, Core R&D Labs, Dow Inc.
As one of the leading materials companies, Dow has set ambitious goals to contribute to a sustainable future through our expertise in material science and collaborative efforts. This talk focuses on material development for the coating industry.
Building a sustainable future presents many opportunities. Coatings are an excellent tool for providing economic advantages by using less material and important functionalities for various applications. While coating solutions in the past were mainly engineered for performance and economics, future coating solutions must seek significant transformations in using safer and sustainable materials, lower energy use, and design for recyclability. Dow has been working on all these aspects in the past decade to support this transformation. Examples include a recyclable barrier coating for paper substrates, wash-off labels to enable low C recycling, and replacement of fluor surfactant to control coating quality.
During this discussion, we also delve into the challenges researchers face in decarbonization, circular economy practices, and developing safer materials.
Title: “Coating Science for Fuel Cell and Electrolyzer Manufacturing”
Scott Mauger, Ph.D. Senior Scientist, National Renewable Energy Laboratory (NREL)
Proton exchange membrane fuel cells and electrolyzers are crucial for the decarbonization of transportation and many industrial sectors that are difficult to directly electrify. To achieve rapidly approaching zero emissions targets, manufacturing of these technologies is in the early stages of expansion. Many companies have announced plans to significantly increase their manufacturing capacity through new facilities or expansion of existing facilities. Roll-to-roll coating will play a principal role in the manufacturing of these technologies as the primary repeat unit of fuel cell and electrolyzer stacks – the membrane-electrode assembly (MEA) – is amenable to established roll-to-roll processes. That said, there are processing challenges that must be addressed to facilitate high-volume manufacturing, including challenges with coating processes, film microstructure, and drying. To address the these challenges the U.S. Department of Energy (DOE) Hydrogen and Fuel Cell Technologies Office (HFTO) has launched a new consortium, the Roll-to-Roll (R2R) Consortium, to conduct process science and engineering research for fuel cell and electrolyzer manufacturing. R2R’s mission is to advance efficient, high-throughput, and high-quality manufacturing methods and processes to accelerate domestic manufacturing and reduce the capital cost of durable and high-performing systems. This talk will provide an overview of the R2R Consortium’s research activities in coating-science topics such as coating process development, formulations, and process modeling.
Title: “Phase Transformations in Metal Halide Perovskites”
Juan-Pablo Correa-Baena, Ph.D. Assistant Professor, School of Materials Science and Engineering, Georgia Institute of Technology
Perovskite solar cells promise to yield efficiencies beyond 30% by further improving the quality of the materials and devices. Electronic defect passivation and suppression of detrimental charge-carrier recombination at the different device interfaces has been used as a strategy to achieve high performance perovskite solar cells. However, the mechanisms that allow for carriers to be transferred across these interfaces are still unknown. Through the contributions to better understand 2D and 3D defects the perovskite solar cell field has been able to improve device performance. Albeit the rapid improvements in performance, there is still a need to understand how these defects affect long term structural stability and thus optoelectronic performance over the long term. In this presentation, I will discuss the role of crystal surface structural defects on optoelectronic properties of lead halide perovskites through synchrotron-based techniques. The importance of interfaces and their contribution to detrimental recombination will also be discussed. Finally, a discussion on the current state-of-the-art of performance and stability of perovskite solar cells will be presented.
