Master's Thesis: "Development of an ALD Layer for Passivating ETL Contacts"

For our group “Silicon Solar Cells”, we are looking for a student assistant to begin as soon as possible, with the opportunity to write a master’s thesis on the topic “Development of an ALD Layer for Passivating ETL Contacts,” for the following tasks:

• The goal of your thesis is to develop a method using atomic layer deposition (ALD) to passivate the interface between the perovskite absorber and the electron contact in perovskite solar cells.
• You will develop the process for depositing the Al O and TiO layer system on our ALD system (FlexAL).
• You will prepare the appropriate test substrates.
• You will measure the optical, structural, and electrical properties of the layers using ellipsometry, UV-vis spectroscopy, and IV measurements.
• You will integrate the developed layers into perovskite solar cells and analyze their functionality within the device.
• You will analyze and present the results.

What you contribute, * 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. (Achtung: nur nutzen, wenn die Stelle Laborbezug hat!)
• 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.

• You are studying a science or technology-related field, such as microsystems engineering, physics, or a comparable discipline.
• You plan and complete tasks independently, to a high standard, and enjoy carrying them out.
• You are proficient in using MS Office.
• You have already successfully demonstrated your excellent written and spoken German and English skills., In addition to the thesis, a contract as a research assistant will be established. The remuneration for this is based on the degree of the academic qualification.

The Fraunhofer-Gesellschaft (www.fraunhofer.com) is one of the world’s leading organizations for application-oriented research. 74 institutes develop pioneering technologies for our economy and society - more precisely: 30 000 people from technology, science, administration and IT. 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.
