Excellent efficiencies have been obtained in liquid environments as well as in prototype upconversion enhanced solar cells, but the research is still focused on the realization of affordable solid states upconverters suitable to be implemented in current solar technologies. We show here that controlled confinement of the upconverting materials in nanostructured or nanosized materials can improve the material performance at low powers. The result presented will show demonstrate how this strategy can represent a crucial guideline for the future development of upconverting photonic devices operating at subsolar irradiances suitable for technological implementation.</span></div> <div><span style="background-color:initial">Angelo Monguzzi is Associate Professor in Condensed Matter Physics at Department of Materials Science of the U</span><span style="background-color:initial">niversity Milano-Bicocca.

Singlet fission relies on precise geometric organization of chromophores, which can be hard to achieve in the desirable solid-state materials. Here, two different self-assembly approaches will be described and the insights we gained from detailed spectroscopic studies will be discussed. We demonstrate that both the environment and the nature of the semiconductor substrates can have large impact on the efficiency and that care must be taken when designing new materials. </span><br /><span style="background-color:initial"></span><div style="background-color:initial;display:inline !important"><span style="font-weight:700"></span></div> <div style="background-color:initial"><br /></div> <div style="background-color:initial">Maria Abrahamsson is Professor of Physical Chemistry at the Department of Chemistry and Chemical Engineering at Chalmers University of Technology.

When: 27 April 2021, at noon (12 am). Place: Online.we will have two presentations dedicated to materials for batteries. Two hot topics will be covered, one on the use of digital twins for battery manufacturing and one on development and advanced modelling of battery electrolytes – from DFT to artificial intelligence.</p>​<span></span><span style="background-color:initial">The webinar is held on the platform zoom.

This encompasses numerous steps and parameters influencing the final electrode properties: porosity, tortuosity, conductivity, etc. And finally affects the electrochemical behavior when the LIB is used in e.g. electric vehicles. The traditional approach to optimize the process is trial-and-error, which is both time consuming and costly. The ERC ARTISTIC project develops a digital twin of the LIB manufacturing process, couples machine learning to multi-scale physical modeling and high throughput experimental characterization. We can already predict with high accuracy the impact of manufacturing parameters on the electrode properties and final LIB behavior, promising to significantly accelerate the manufacturing optimization. <br /><br /></div> <div>Prof. Alejandro A. Franco at the Université de Picardie Jules Verne (Amiens, France) is Junior Member of the Institut Universitaire de France and leads the Theory Open Platform of the ALISTORE European Research Institute. He is an expert on multiscale modeling and AI/ML techniques applied to battery research, and most notably has an ongoing ERC project on this topic: <a href="">ARTISTIC. </a></div> <div><br /></div> <div><strong><img src="/sv/styrkeomraden/material/kalendarium/PublishingImages/Patrik.jpg" alt="Patrik Johansson" class="chalmersPosition-FloatRight" style="margin:5px" />Advanced Modelling of Battery Electrolytes – From DFT to Artificial Intelligence </strong></div> <div>The impact of battery technology on society is tremendous and it is a feat of materials science. However, we still need more understanding to enable truly rational optimization, especially w.r.t. the electrolyte &amp; the electrolyte/electrode interfaces. By looking at various structure-dynamics relationships using a wide tool-box of modelling techniques and protocols, we can indeed reveal many profound details. Some examples targeted by DFT are the fundamentals of ligand-exchange and transport mechanisms, very important for more “exotic” systems, such as highly concentrated electrolytes, where many simplifications and the traditional know-how breaks down. At the other end we find artificial intelligence to be useful to evaluate the habits of researchers(!), but also for much more mundane things such as to classify electrolytes.<br /><br /></div> <div>Prof. Patrik Johansson at the Department of Physics at Chalmers has for &gt;25 years combined understanding of new materials at the molecular scale, often via ab initio/DFT computational methods and IR/Raman spectroscopy, with battery concept development and real battery performance. His special interest is different kinds of electrolytes stretching from liquids via gels and polymers to solids. He focuses on various next generation battery technologies: Na-ion, Li-S, Mg, Ca, Al, etc. Prof. Johansson was recently appointed vice-director of the Graphene Flagship and is also co-director of the ALISTORE European Research Institute. In 2015 his team won the Open Innovation Contest on Energy Storage arranged by BASF for his new ideas on Al-battery technology (prize sum 100,000€) and he recently started Compular AB together with two of his PhD students to market the CHAMPION software. </div> <div><br /></div>
