Flash infrared annealing as a cost-effective and low environmental impact processing method for planar perovskite solar cells
Abstract For successful commercialization of perovskite solar cells, straightforward solutions in terms of environmental impact and economic feasibility are still required. Flash Infrared Annealing (FIRA) is a rapid method to fabricate perovskite solar cells with efficiencies >18% on simple, planar architecture, which allows a film synthesis in only 1.2 s, faster than the previous report based in a meso architecture and all of them without the usage of antisolvent. In this work, through a comparative study with the common lab-scale method, the so-called antisolvent (AS), the main photovoltaic parameters and working mechanisms obtained from impedance spectroscopy (IS) measurements show simil…
Online Meetings in Times of Global Crisis: Toward Sustainable Conferencing
International conferences are an essential component of the timely exchange of ideas and results in the scientific community, where scientists present their results, gain new insights, and meet colleagues and collaborators. In early 2020, a global pandemic caused by a coronavirus (SARS-CoV-2) and the corresponding disease (covid-19) resulted in a number of conferences being canceled or postponed. (1) To foster scientific exchange despite the restrictions, a range of initiatives were launched across the globe to move international conferences online. (2−8) [...]
