PhD Student for Tomorrow's Solar Cells and Wearable Electronics

Ref REF 2023-0592

We are looking for a highly motivated PhD student to join our team working on solar cell, bioelectronics and wearable electronics. The aim to design sustainable materials for future. The project is supported by the Knut and Alice Wallenberg Foundation. The project brings together 5 research groups from Chalmers University of Technology and Linköping University, led by Christian Müller, Anna Martinelli, Eva Olsson, Mats Fahlman and Simone Fabiano. The mission of the project is the realization of doped organic semiconductors that display truly stable electronic behaviour. You will be part of a team of five PhD students, as well as several Postdocs, who will together develop and study new materials concepts that facilitate stable doping. We have an extensive international collaboration network that is a resource for your work where you will have access to the forefront expertise and top-of-the-line facilities.

Doping is essential for the optimization of the electronic performance of organic semiconductors, and as such essential for a wide range of emerging technologies from sustainable energy harvesting via organic photovoltaics and thermoelectrics to wearable electronics and bioelectronics. The doping process involves a chemical or electrochemical reaction that allows to tune the electrical and electronic properties of an organic semiconductor. The resulting doped state, however, is prone to evolve with time, which limits the lifetime of electronic devices.

Project description
The project will leverage concepts from the field of molecular glasses to realize stable organic semiconductors and devices. Your specific project will entail a detailed study of the phase behaviour and glass formation of dopant/semiconductor pairs, using a suite of characterization methods from thermal and mechanical analysis to optical spectroscopy and various scattering techniques.

It can be anticipated that the project will have considerable impact on the field of organic electronics by enabling the more widespread usage of some of the most promising materials, which will accelerate further development of many emerging technologies.

Information about the division
The Eva Olsson Group focuses on the correlation between fine scale material structure, down to the atomic level, and material properties using advanced electron microscopy. All research is conducted in co-operation with other universities/institutes and/or industry. Presently, the group consists of 1 Professor, 1 guest professor, 2 permanent researcher, 3 Postdocs and 3 PhD students.

Major responsibilities
The majority of your working time is devoted to your own research, in collaboration with postdocs and students at Chalmers and Linköping University. As a PhD student you are expected to develop your own ideas and communicate scientific results orally as well as in writing. In addition, 10-20 percent of your time will be dedicated to departmental duties, especially teaching on the undergraduate level.

The successful candidate must have a Master’s degree in Physics, Materials Science or equivalent (or be in the process of completing a Master’s degree). Experience with electron microscopy is required; experience with polymer science is a merit. Due to the interdisciplinary nature of the work, the candidate is expected to have excellent collaboration skills. A very good capability of communicating scientific results in English, both orally and in writing is required.

Contract terms
Full-time temporary employment. The position is limited to a maximum of five years.
