嘉宾简介:
Monica Lira-Cantu is Full Professor and Group Leader of the Nanostructured Materials for Photovoltaic Energy Group at the Catalan Institute of Nanoscience and Nanotechnology (ICN2) in Barcelona, Spain. Her research interests are the synthesis of novel nanomaterials and the control of their optoelectronic properties through their manipulation at molecular level, with the aim of developing very stable and highly efficient perovskite solar cells. She obtained her PhD in Materials Science in 1997 and worked as a staff chemist for ExxonMobil Research & Engineering (USA) and returned to Spain in 2001 obtaining a Permanent research position in 2006. She was visiting professor at EPFL (Switzerland) in 2018 and has been visiting scientist at the Center for Advanced Science and Innovation (Japan), Oslo University (Norway), and the Risø DTU National Laboratory for Sustainable Energy (Denmark). Fellow of the Royal Society of Chemistry (FRSC) and the Cannon Foundation in Europe. She is currently Editor-in-Chief of APL Energy (AIP Publishing) and Advisory Editorial Board for Discovery Materials and Springer Nature Applied Sciences (Nature); Adv. Energy and Sustainability (Wiley); Chemical Physics Impact (Elsevier) and Matter (Cell Press). She has more than 135 publications, including 125 published articles in scientific journals, one book, 10 book chapters, and 11 patents. She is a reviewer for more than 45 scientific organizations and more than 50 scientific journals.
报告摘要:
With record efficiencies above 26 % for single junction and above 34 % for Silicon-Perovskite tandem, Perovskite solar cells (PSCs) have demonstrated to be a superb player for the energy supply of our future. However, soon after the emergence of this technology back in 2009-2012, the research community recognized the need for the understanding and management of degradation mechanisms to boost cell device stability, module reliability and, in general, device lifetime. Additive engineering has become one of the most attractive pathways to enhance PSC stability. The interaction of their functional groups with the halide perovskite (HP) absorber, as well as with the transport layers, results in defect passivation and ion immobilization improving device performance and stability. In this talk, we will briefly summarize the different types of strategies recently applied in PSC to enhance not only efficiency but also long-term operational stability. My talk includes the application of organic additives which can passivate exclusively shallow defects and thus immobilize ion, or the application of additives and 2D materials, such as MXenes, working as transport layers in PSC. Special emphasis is given to their effect on the stability of PSCs under environmental conditions such as humidity, atmosphere, light irradiation (UV, visible) or heat, considering the recently reported ISOS protocols, especially outdoor testing. Finally, I will also show our most recent results on in-situ characterization of PSCs under accelerated tests or our results in Machine Learning.
