Descripción
We are looking to recruit a PhD researcher in the group of Dr. Gillett in the Electronic and Photonic Materials division in the Department of Physics, Chemistry, and Biology (IFM). The successful applicant will work in collaboration with the Swedish company Epishine AB on a research project funded by the Åforsk Foundation that will use ultrafast optical spectroscopy to understand the degradation mechanisms of organic photovoltaics. The recruited researcher will also have the opportunity to take advantage of the state-of-the-art spectroscopy setups developed in the group to pursue their own research interests more broadly in the field of organic materials. Topics currently being studied in the group include organic photovoltaic and OLED systems, vibronic coupling in organic molecules, molecular photoswitches, circularly polarized luminescence, and photocatalysis. Your work assignments This project aims to understand the stability and failure mechanisms in the light-absorbing layer of organic photovoltaic devices under conditions relevant to commercial applications. To achieve this, we will take a unique approach that involves using ultrafast optical spectroscopy techniques to probe how material degradation impacts the fundamental photophysics of the organic materials that underpin device operation (see https://doi.org/10.1016/j.joule.2023.03.002 for a recent example of this approach from the group). This project will be carried out in collaboration with the Swedish company Epishine AB ( https://www.epishine.com /), also based in Linköping, who are currently working on the commercialization of organic photovoltaics for indoor light harvesting applications. You will be responsible for performing transient absorption spectroscopy measurements, spanning the visible to mid-infrared, on organic photovoltaic samples provided by Epishine AB to understand how the photophysics of these materials change after different material degradation protocols. This will be supplemented b
