Studies of Spin Sensitive Processes in Organic Solar Cells
We invite applications from highly motivated candidates interested in doctoral studies on the above research topic to gain new insights into fundamental processes in organic solar cells. In return, the successful candidates will be excellently supervised by the principal investigators, will collaborate with other doctoral students in the group as well as within an international consortium and will have the opportunity to present their results on international conferences as well as to obtain a PhD degree. All research and training activities are part of the EU-funded International Training Network SEPOMO. The doctoral project will include three secondments (2 or 6 months) at partnering groups at the Université Angers (France), Fundació EURECAT (Spain) and University of Oxford (United Kingdom). We expect successful candidates to write a doctoral dissertation at the end of their studies.
Background information: Organic Solar Cells possess tremendous advantages concerning possible applications and production costs, due to the possibility to print them from ink in a roll-to-roll process. Nevertheless, the power conversion efficiency and the lifetime of the organic semiconductor-based solar cells need to be improved. To overcome these issues, intensive fundamental collaborative research efforts are necessary to clarify the intermediate processes during the conversion process of light into electric energy. Some of these processes involve spin-interactions and need therefore be addressed by spin-sensitive techniques.
Project: Various experiments will be performed that are based on the principles of optical spectroscopy and electron spin resonance. Both, organic semiconductor films, as well as fully processed devices will be studied in a broad temperature range between ambient and cryogenic temperatures. In particular, the intermediate excited states, such as triplets, polarons and charge transfer excitons will be addressed and studied individually within this project. The basic principle is to use the spin of excited states as a probe for their molecular environment to gain further insights into the processes taking place in organic solar cells.
Profile: The successful candidate must have a completed MA (or equivalent) in physics, material sciences or related fields with experience in cw and time resolved optical spectroscopy and/or magnetic resonance. Knowledge of programming languages such as Mathematica, Origin, LabView is extremely important. Appropriate skills in English speaking and writing are mandatory.
