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

Fraunhofer · Freiburg, DE, 79110

Posted · Deadline:

Project description

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 write your thesis on this topic? With us, you’ll find the experts and the environment you need to make these goals a reality. You will support our “Silicon Solar Cells” group, which focuses on the development of high-efficiency silicon solar cells and silicon-based tandem solar cells. To achieve the highest possible efficiencies with perovskite/silicon tandem solar cells, effective engineering of the interfaces is necessary. Layer systems consisting of Al₂O₃ and TiO₂ have the potential to improve the interface between the perovskite absorber and the electron contact by both effectively passivating the surface and increasing stability. 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 Al₂O₃ and TiO₂ 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.
