A magnifying glass to elucidate their rise in photovoltaics: atomistic simulations of organic halide perovskites
BLOG News & Events A magnifying glass to elucidate their rise in photovoltaics: atomistic simulations of organic halide perovskites DATE Date: June 20, 2023 – at 11.00 AM (Italian time)Where: Aula P1A, Complesso Paolotti, Via Giambattista Belzoni 7, 35131, Padova Organic inorganic hybrid halide perovskites (PSCs) have emerged as promising class of materials for solar cells. Thanks to their remarkable optical properties such as high absorption coefficient, tunable bandgap, high charge carrier mobility and low exciton binding energy, PSCs facilitate high power conversion efficiencies (PCE). Indeed, the PCEs of PSCs have rapidly risen since 2009 from 3.8% to a certified 26.2% in 2022. Most of these rapid advances are due to changes in the preparation conditions, however the connection to the underlying processes at the atomic level is basically missing. Computer simulation can in principle elucidate the atomistic mechanisms behind these phenomena, but the systems involved are highly complex involving multiple species and high activation barriers. Our approach entails the development and application of theoretical and multiscale computational modeling spanning the electronic and atomistic length scales. Classical molecular dynamics (MD) is embedded with ab-initio MD and density functional theory simulations to have an outright description of the physics behind the mechanisms responsible for long-term stability and improvement of the optical properties for PSCs. conference speakers : Virginia Carnevali Virginia Carnevali is a scientist in Ursula Röthlisberger’s group at the Institute of Chemical Sciences and Engineering Ecole Polytechnique Federale de Lausanne EPFL, Switzerland. She has research experience in the theory and simulations of structural, electronic, magnetic, optical, transport, and thermal properties of 2D materials, topological materials, thermoelectric materials, and solar cells. Virginia has also developed an interest in researching useful applications of quantum computing to solved condensed matter problems. Her research has focused on understanding the physics and crucial mechanisms that make a material attractive for renewable energy applications. She recently demonstrated – for the first time –that coupling of rotating lone pairs and the vibrational motion is an effective mechanism to achieve ultralow thermal conductivity in crystalline materials. Virginia is currently studying perovskite-based solar cells, one of the most promising photovoltaic solutions because of their efficient solar-power conversion, low cost and simple manufacturing process. Her efforts are aimed at improving the optical performance of this class of materials by seeking effective techniques for defect passivation, phase stabilization, and improved of charge carrier transport at the interfaces.

Threats to Sustainability under Climate and Societal Change
BLOG News & Events Threats to Sustainability under Climate and Societal Change Physics and Societal Challenges – Innovator talk – Seminar series Speaker: Paolo D’Odorico Title: Threats to Sustainability under Climate and Societal Change Date: May 12, 2023 – at 11.15 AM (Italian time) Where: Aula Rostagni, Via Paolotti 9, 35131, Padova Abstract The increasing water demand by human societies raises concerns about the extent to which it is possible to feed the world with the limited freshwater resources of the planet. The emergent competition for water between human uses and environmental needs limits the development of suitable water security scenarios for a sustainable future. Human appropriation of water resources is for large part instrumental to the enjoyment of human rights to food. To what extent can such rights be reconciled with other human needs as well as the needs of Nature? Here we show how humanity is placing unprecedented pressure on the global agricultural system and its water resources while reshaping the patterns of water dependency through teleconnections between consumers and production areas. Through a suite of ecohydrological and socio-environmental analyses, we evaluate the biophysical and social justice limits to the sustainable use of water resources through a variety of perspectives accounting for hydrologic constraints, environmental needs, societal resilience, food security, and globalization. READ MORE Conference speaker Paolo D’Odorico is Professor of Hydrology at the Department of Environmental Science, Policy, and Management at UC Berkeley. He has research expertise in Ecohydrology, Surface Hydrology, Ecosystem Ecology, Aeolian Processes, Desertification, Stochastic Nonlinear Environmental Dynamics and Water and Food Security, with about 300 publications in these topics. Prof. D’Odorico’ research focuses on the role of hydrological processes in the functioning of terrestrial ecosystems and his work has highlighted important nonlinearities in the coupling between soil moisture dynamics and plant water stress, biogeochemical cycling, land-atmosphere interactions, plant community composition, and soil susceptibility to wind erosion. Prof. D’Odorico is currently investigating the globalization of water through virtual water trade and international land investments, and its impact on water equity, societal resilience, environmental stewardship, and food security. Prof. D’Odorico has been awarded the Hydrological Sciences Medal (American Meteorological Society), the Paul Witherspoon Lecture Award (American Geophysical Union), the Sustainability Science Award (Ecological Society of America). He is a Fellow of the American Geophysical Union, American Association for Advancement of Science, and The John Simon Guggenheim Memorial Foundation. other posts All Posts Appointments Communications 9 Giugno 2023 A magnifying glass to elucidate their rise in photovoltaics: atomistic simulations of organic halide perovskites Read More 8 Giugno 2023 Modelling and quantifying robustness of interconnected systems: at the crossroad of network science and A Read More 22 Maggio 2023 Before and after chatGPT: chances, changes, and opportunities of large language models in research Read More Load More End of Content.
