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 well known for its innovative research in the field of inorganic and organic-inorganic hybrid thin-film photovoltaic and battery technologies. The Laboratory holds the world record power conversion efficiency of flexible CIGS and all-perovskite tandem solar cells. We are offering
Several PhD Positions on All-perovskite Multi-junction Solar Cells and Mini-module on Flexible Substrates
We are looking for several highly motivated PhD students with a strong experimental background in materials, chemistry, and physics to develop high-efficiency and stable all-perovskite multi-junction solar cells and mini-modules on flexible substrates. You will have the opportunity to be embedded in a collaborative Horizon Europe research project. This will enable you to interact and collaborate with leading European academic and industrial partners.
Your responsibilities (will vary depending on different projects) include:
- Develop high-throughput combinatorial materials synthesis platforms using thermal evaporation and/or thermal evaporation/slot-die coating method to accelerate the discovery of novel perovskite compositions
- Develop solution-processed (e.g., spin coating, slot-die coating) wide bandgap (~ 1.8 eV) and narrow bandgap (~ 1.2 eV) perovskite absorbers with both excellent optoelectronic properties and stability
- Develop high throughput characterizations and in-situ/operando characterizations using electrons, photons, X-rays, ions, etc. to characterize the materials, layers, and devices (e.g., single-junction and multi-junction perovskite solar cells), and interpretation of results
- Layer deposition and device integration (e.g., single-junction and multi-junction perov-skite solar cells) using various deposition techniques, notably high-vacuum thermal evaporation, magnetron sputtering, atomic layer deposition (ALD) and slot-die coating etc.
- Conduct in-depth loss mechanisms analysis and use these insights to further improve the performance of perovskite single-junction and multi-junction solar cell and mini-modules
- Develop and implement novel concepts, such as light management, new materials and processing methods, novel tandem architectures, optical and electrical simulation, etc., to understand and ultimately improve the performance (both efficiency and stability) of flexible all-perovskite tandem solar cells and mini-modules
- Stability tests of single junction and multi-junction perovskite solar cells and mini-modules
- Dissemination of the results on meetings, reports, scientific journals and at conferences
- Maintenance of equipment in collaboration with the laboratory technician
- Co-supervision of semester- or master students together with supervisor
- Master degree in Material science, Physics, Chemistry, Chemical Engineering or related fields
- Strong background in semiconductor technology
- Strong experimental and analytic skills
- Skills in programming/machine learning/CorelDraw are advantageous
- Experience in the field of halide perovskite semiconductors is advantageous
- Excellent interpersonal skills to communicate with colleagues and superiors
- Ability to work in a collaborative team environment toward a common goal
- Good English skills are required and good German language skills is a plus
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. You will be working at Empa Dübendorf, near Zurich, and enrolled at ETH Zurich.
The starting date is May 2023 or upon mutual agreement. The PhD project is planned for 4 years.
