Be part of change

You will support our team Perovskite Thin-Film Photovoltaics which aims to improve the efficiency stability and scalability of perovskite solar cells - a key technology in the sustainable energy world. We offer you the opportunity to contribute to innovative research. You will work with a diverse international team that is committed to pushing the boundaries of photovoltaic research.

To support our team Perovskite Thin-Film Photovoltaics we are seeking a student assistant starting 01.04.2026 with the opportunity to develop a Masters thesis for the following activities:

• Your main task will be the fabrication of perovskite thin-film solar cells primarily based on solution-processed multi-layer structures.
• You will prepare precursor solutions deposit layers using methods such as spin coating or thermal evaporation and produce complete solar cells.
• You will characterize the solar cells with optoelectronic and optical methods including currentvoltage measurements and photoluminescence microscopy/spectroscopy and analyze the resulting data with common analysis tools (e.g. Origin or Python).
• You will document your experiments carefully interpret your measurement results clearly and structurally and discuss them in the team.
• Additionally you will support the organization of laboratory workflows by contributing to clean and safe workspaces and reliable experimental processes.

What you contribute

• You are studying physics chemistry materials science or a comparable field.
• You have a strong interest in experimental lab work.
• Experience with fundamental optical or electrical characterization methods (e.g. IV PL) is advantageous.
• Ideally you have practical experience in a cleanroom environment and are familiar with thin-film systems.
• You enjoy working in a team but after proper training you can plan and carry out tasks independently.
• You approach your tasks in a structured and conscientious manner.
• You have good English skills.

What we offer

• Exclusive insight: By collaborating with the scientists in our research unit you will gain an overview of the daily life of research and development at a research institute.
• Labor infrastructure: At Fraunhofer ISE we work with state-of-the-art facilities and equipment enabling research projects to be conducted at the cutting edge.
• Research mix: You will have the opportunity to combine experimental work with theory applying and expanding your knowledge from your studies.
• Support: You will be mentored by scientists and will receive feedback on your progress.
• Teamwork: Through interaction with scientific and student staff you will gain experience working in a team and can contribute your own experiences.
• Working hours and location: We offer flexible working hours to accommodate your needs in coordination and occasional remote work from home is possible.
• Equality of opportunity: We value equal opportunities and foster diversity.
• After work: Celebrate with your colleagues at after-work events or our annual staff celebrations.
