[Aspuru-Guzik group list] Group Meeting, Oct 21, 11 AM, M217

by Ian Kivlichan

Hi all, Tomorrow Rafa will give group meeting. Note that this will be in the new time for the rest of the semester (Wednesdays at 11 AM), but in a nonstandard location, M217 which is in the Department Centre. For the rest of the semester we'll be back in the Div Room but still at the Wednesday 11 AM slot. See below for the title and abstract. Best, Ian ------------------------------------- Speaker: Rafa Gómez-Bombarelli Title: Electrolytes for flow batteries: Episode VII - The electrophile awakens Abstract: In this new installment of an epic saga, we report progress in the high-throughput search for organic electrolytes for aqueous flow batteries. A brief introduction picks on the humble beginnings by C Suh, S Er, A Aspuru-Guzik and collaborators (Nature 2014 505, 195-198; Chem Sci 2015 6 885), after which we will discuss recent advances. The following topics will be discussed (i) library generation and reaction pathways; (ii) quantum-chemical prediction of key performance parameters (redox potential, aqueous stability, acid dissociation); (iii) single electrolyte solutions for flow batteries; (iv) organic electrolytes beyond quinones.

[Aspuru-Guzik group list] Excitonics Perovskite Seminar: Matt Klug - Oct 27 - noon in 36-428

by Catherine M Bourgeois

Please post and forward to your groups EXCITONICS Perovskite Seminar Series Computational and Experimental Screening of Mixed-Metal Perovskite Compositions* October 27, 2015 at 12 noon/36-462 Matthew Klug MIT/Department of Biological Engineering [klug] Although solar cells with impressive power conversion efficiencies have been demonstrated using lead-based metal halide perovskites, there are concerns regarding the inherent toxicity and long-term stability of these materials. This talk will focus on recent computational and experimental efforts that explore the feasibility of simultaneously addressing both of these issues by fabricating active layers with mixed-metal compositions, where a portion of the metal content in the perovskite film has been replaced with an alternative, less-toxic metal species. Relevant electronic properties such as the material band gap, carrier effective masses, and band edge locations were theoretically evaluated using density functional theory (DFT). By computationally screening through a series of mixed-metal compositions that spans the periodic table, several promising candidates were identified that preserve the excellent electronic properties of the methylammonium lead triiodide perovskite, MAPbI3, while simultaneously reducing material toxicity. The computational effort was paired with an exhaustive experimental screening study that systematically evaluated how replacing various amounts of lead with nine different metal species impacts material and electronic properties as well as device performance. These findings reveal that introducing a second metal species can influence film morphology, modify the material band gap, shift the band edge locations, impact photoluminescence, and improve photovoltaic performance. The aggregate data provides enough information for us to propose feasible physical mechanisms that explain trends in performance and are consistent with both empirical observations and computations. Furthermore, this work will present preliminary results that suggest some mixed-metal compositions also demonstrate superior resistance to degradation at elevated temperatures. While further experimentation is required to evaluate whether mixed-metal compositions would improve performance of solar cells utilizing different device architectures or perovskite synthesis techniques, this study presents encouraging evidence that introducing alternative metal species can have beneficial impacts on device performance and stability, while simultaneously mitigating toxicity. Matt Klug is a post-doctoral researcher in Prof. Angela Belcher's Biomolecular Materials Group at MIT, where he studies emerging solution-processed solar cells and synthesizes photoactive nanocomposites using biological materials. *This talk is part of the Perovskites Seminar Series organized by Sam Stranks and sponsored by the Center for Excitonics.

[Aspuru-Guzik group list] Excitonics Seminar: Tyrel McQueen, TODAY, 4-349, 4:30 PM

by Catherine M Bourgeois

TODAY - Please post and forward to your groups ---------------- Probing Electrons and Vibrations in Functional Materials October 20, 2015 at 4:30pm/Pappalardo Room: 4-349* Tyrel McQueen Department of Chemistry, Department of Materials Science and Engineering, Department of Physics and Astronomy, Institute for Quantum Matter, The Johns Hopkins University [TyrelMcQueen] Developing models to predict the behavior of new inorganic solids and design materials with desirable physical properties relies on accurate determination of structure, including the orbital, spin, and charge character of the active electrons. In most real materials, properties are driven by local interactions; however, structural information has typically been constrained to average details from diffraction experiments, or direct imaging of individual atoms/molecules but with the loss of detailed knowledge of the dynamics. Recent advancements in total x-ray and neutron scattering have enabled robust local structure information using pair distribution function (PDF) techniques, which, with appropriate analysis methods, can finally allow us to develop a fundamental understanding of the origin of useful electronic phenomena. In this talk, I will present our recent work on applying chemical group theory methods to the interpretation of PDF data to extract meaningful information about the dynamics in a variety of functional materials. Tyrel McQueen is an Associate Professor of Chemistry at John Hopkins University in Baltimore. He received his BS in Chemistry from Harvey Mudd College in 2004, and his MA (2006) in Chemistry and his PhD (2009) in Chemistry and Materials from Princeton University. His research group is interested in solid state chemistry materials design and synthesis techniques; experimental condensed matter physics, quantum magnetism, and heat- and light-induced charge separation through strong electron correlations; superconductivity. An expanded description of current research can be found athttp://occamy.chemistry.jhu.edu/research/index.php A list of publications are available at: http://occamy.chemistry.jhu.edu/publications/index.php *NOTE CHANGE IN ROOM Light refreshments will be served.

[Aspuru-Guzik group list] Post-Doctoral Candidate Visit

by Doran Bennett

Hi Everyone, Prineha Narang <http://daedalus.caltech.edu/team-member/prineha-narang/> will be visiting us on Thursday Nov. 19th. Her previous work includes electronic structure calculations of semi-conductor band gaps and predictions about hot carrier generation from surface plasmon decay. Since her background aligns with both some problems in excitonics and in photovoltaics, I think many of us will be interested in conversations with her. Please let me know if you are interested in meeting her and what your availability is. I will disseminate the schedule for the day as well as the abstract and title of her talk closer to the date. Best, Doran
