Empa - the place where innovation starts
Empa is the research institute for materials science and technology of the ETH Domain and conducts cutting-edge research for the benefit of industry and the well-being of society.
The Laboratory for Thin Films and Photovoltaics is known for its innovative research in the field of inorganic and or-ganic-inorganic hybrid thin film photovoltaic and battery technologies. The Laboratory holds the world record for en-ergy conversion efficiency of Cu(In,Ga)Se2 (CIGS) solar cells on flexible substrates, which technology is upscaled by a spin-off company of the Laboratory. The lab is also one of the leading players for photovoltaic tandem devices. We are offering a
PhD Student position in the field of thin-film solar cells
We are looking for a student motivated to contribute to the development of thin-film CIGS photovoltaic devices. The researcher in this position is responsible for the fabrication and characterization of solar cells and layers based on the CIGS material system. The researcher goals are to understand and overcome limitations of devices based on new alloyed CIGS absorbers with high bandgap, explore the absorber processing limits and develop electrical contacts, in view of new applications such as bifacial and semi-transparent solar cells for tandem applications.
Your responsibilities include:
- Plan and conduct experiments to develop the scientific understanding and improve the performance of CIGS solar cells
- Devices fabrication using various deposition techniques, notably high-vacuum coevaporation, chemical bath deposition, magnetron sputtering, atomic layer epitaxy and thermal/e-beam evaporation
- Characterization of materials, layers and devices, interpretation of results
- Dissemination of the results in reports, scientific journals and at conferences
- Maintenance of equipment in collaboration with the laboratory technician
- Co-supervision of semester- or master students
- MSc in Material science, Physics, Chemistry, Electrical engineering or similar
- Previous experience with thin film deposition techniques or photovoltaic devices is an advantage
- Willingness to conduct independent, target driven research
- Clean and diligent working method including precise record keeping
- Excellent English both in writing and speaking
- Ability to work in a collaborative team environment towards a common goal
- Good interpersonal skills to communicate with colleagues, superiors and stake-holders
We offer an international, highly stimulating research environment with excellent infrastructure and broad interdisciplinary surroundings with plenty of possibilities for personal and professional development. You will work on important and promising solutions to the global energy problem in an international environment. The starting date is spring or early summer 2023 or upon mutual agreement.
