They know: Anyone who comes to Fraunhofer wants to and can make a difference. For themselves, for us and for the markets of today and tomorrow.

As one of the world's largest solar energy research institutes, the Fraunhofer Institute for Solar Energy Systems ISE makes a significant contribution to a sustainable, economical, secure, and socially equitable energy supply worldwide. Our goal is to advance the energy transition by providing concrete, implementable technological solutions through excellent research results, successful industrial collaborations, and spin-offs. To this end, our ~1,300 employees conduct research in four key areas: energy supply, energy distribution, energy storage, and energy utilization. Fraunhofer ISE's state-of-the-art R&D infrastructure, with 22,300 m² of laboratory space, enables cutting-edge research at an international level.

Be part of change

Would you like to play an active role in shaping the energy transition and gain practical experience during your studies? With us, you’ll work as a student assistant to help make this goal a reality.

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

For our team “Perovskite Thin-Film Photovoltaics”, we are looking for a student assistant starting 01.10.2026, with the opportunity to write a master’s thesis, to perform the following tasks:

• You will investigate the use of novel materials with a lower environmental footprint and analyze their effect on the efficiency and stability of perovskite thin-film solar cells.
• You will prepare coating solutions, apply functional layers using methods such as spin coating or thermal evaporation, and thereby fabricate complete solar cells yourself.
• You will characterize the solar cells using optoelectronic and optical methods, including current-voltage measurements and photoluminescence spectroscopy, and evaluate the resulting data using standard analysis tools (e.g., Origin or Python).
• You will carefully document your experiments, interpret your measurement results in a clear and structured manner, and discuss them with the team.
• In addition, you will support the organization of laboratory operations by contributing to clean and safe workstations as well as reliable experimental processes.

What you contribute

• You are studying physics, chemistry, materials science, or a related field.
• You have a strong interest in experimental laboratory work. Experience with basic optical or electrical characterization methods (e.g., IV, PL) is a plus.
• You enjoy working in a team, but after appropriate training, you can also plan and carry out tasks independently.
• You approach your tasks in a structured and conscientious manner.
• You have a good command of English.

What we offer

• Exclusive insights: By working together with the scientists in our department, you will gain insights into the day-to-day research and development work at a

research institute.

• Laboratory infrastructure: At Fraunhofer ISE, we work with state-of-the-art equipment and devices so that research projects can be carried out using the latest

technology.

• Research mix: You will have the opportunity to combine experimental work with theory, thus applying and expanding the knowledge you gained during your

studies.

• Supervision: You will be supervised by scientists during your work and receive feedback on your progress.
• Teamwork: You will gain experience in working in a team with our scientific and student staff and can contribute the experience you have already gained.
• Working hours and location: We offer you the opportunity to flexibly adjust your working hours to your needs and to occasionally work from home.
• Equal opportunities: We value equal opportunities and embrace diversity.
• After work: Celebrate yourself and your colleagues at after-work events or our annual employee parties.

Remuneration is based on the degree of the academic qualification.

We value and promote the diversity of skills among our employees and therefore welcome all applications - regardless of age, gender, nationality, ethnic and social background, religion, ideology, disability, and sexualorientation and identity. Severely disabled persons will be given preference in case of equal qualification.

Ready for a change? Then apply now with your compelling application documents (including CV, cover letter, and references/performance records) and make a difference! After your online application is received, you will receive an automatic acknowledgment. We will get back to you as soon as possible to tell you how the process continues.
