Reference No. SE 2024/18

The Department Interface Design is looking for

PhD (f/m/d) for the X-Ray Spectroscopic Characterization of Functional Interlayers in Perovskite Solar Cells

Your Tasks

• Characterization of functional interlayers in perovskite solar cells and its interfaces using X-ray spectroscopic methods. The focus is on revealing the chemical and electronic structure of surfaces and buried interfaces in layer stacks provided by project partners. Use of various X-ray probes to analyze the chemical and electronic structure of the involved surfaces, interfaces and material volume, which should provide crucial insights for a knowledge-based optimization approach.
• Support the further development of spectroscopic methods for the characterization of halide perovskite photovoltaics.
• Participate in development of methods and apparatus for operando spectroscopy of photovoltaic materials.
• Writing beamtime applications, organizing and supporting synchrotron measurement campaigns. Coordinating exchange of samples and findings with project partners.
• Presentation and publication of results at international conferences/workshops and in peer-reviewed journals.

Your Profile

• We are looking for a highly motivated and curious scientist holding a MSc degree in physics, physical chemistry, or material science.
• Knowledge in the operation of ultrahigh vacuum equipment and using X-ray spectroscopies is highly beneficial.
• Background in photovoltaic materials research is appreciated but not required (enthusiasm for such topics is strongly recommended!).
• We will expect from you an independent communication and collaboration with project partners to organize sample exchange and measurement campaigns.
• Excellent English communication skills are necessary. Additional German skills are advantageous. High level of intercultural competence and ability to work in a team is necessary.

We ask you to enclose the following documents with your application:

• Motivation letter, including your research interests.
• Curriculum vitae with the stages of your career, publications, research experience and the contact details of at least two scientific references
• Certificates and grades
