About us:

The Aydin Research Group, headed by Dr. Erkan Aydin, at the Department of Chemistry of the LMU Munich pursues a strong research program on high-efficiency thin film-based single and multi-junction solar cells. The group's focus is on developing high-efficiency and stable photovoltaic technologies. With this focus, the group approaches technological advancements from multiple angles, spanning material innovation to device fabrication, encompassing process and property optimization, as well as modeling and testing of solar cells in realistic working environments aiming to advance them towards industrial upscaling.

We are looking for you:

Postdoctoral researcher in perovskite-based tandem solar cells (m/f/x)

in Munich

Your tasks and responsibilities:

Metal halide perovskites are high-quality semiconductors due to their high absorption coefficient, long carrier diffusion lengths, and remarkable defect tolerance. As a result, perovskite solar cells (PSCs) have emerged as a ‘paradigm shift’ in the PV field, with PCEs >26% (AM1.5G, Earth spectrum). PSCs are particularly appealing for tandem PVs thanks to their bandgap tunability between 1.18–2.30 eV. Tandem PVs promise higher PCEs by reducing thermalization losses. This is achieved by splitting the solar spectrum into multiple subcells that are optimized to a specific range. Initially, PSCs were coupled with c-Si in tandem form, and this concept recently reached ~34% PCE. Meanwhile, we can replace c-Si bottom cells with perovskites, and form all-perovskite tandem solar cells. Both these device configurations are of interest in our project, and we would like to make them stable in space extremes and test them in the real space environment.

In this position

  • You will actively contribute to the development of high-efficiency perovskite-based tandem solar cells and work closely with the group’s PhD students.
  • You will conduct the specific device characterization, experimental loss analysis, and simulation of single- and multijunction solar cells.
  • You will evaluate the feasibility of the perovskite-based tandem solar cells for space applications with space-specific testing protocols.
  • You will be responsible for the hands-on processing of individual process steps.
  • You will coordinate the development work and experiments in cooperation within LMU Munich and other institutes.
  • You will manage the assigned project tasks towards successful completion.  
  • You will disseminate the research outputs in project meetings, peer-reviewed journals, and international conferences.
  • You will write regular reports for the project outputs.

Your qualifications:

We are seeking candidates with:

  • Solid background in the fabrication of highly efficient perovskite solar cells more specifically perovskite-based tandem solar cells.
  • The position, focusing on device fabrication, demands a high level of experimental skills and involves operating sophisticated deposition equipment.
  • Essential skills include the ability to design and conduct experiments, utilize advanced characterization techniques, and interpret measured data.
  • The candidate is expected to work collaboratively in a strongly interconnected team and should demonstrate the ability to thrive in a team environment.
  • Personal attributes sought include a strong sense of responsibility, high motivation for innovation and excellence, and flexibility to work efficiently and deliver results.
  • Applicants are required to possess a PhD degree in physics, chemistry, engineering, materials science, or closely related fields.
  • Applicants must have good spoken and written communication skills.


  • Being part of the internationally connected research group, and building a wide network.
  • Working in an inclusive, dynamic, international, and academically stimulating environment.
  • Working in a place that can be accessed by public transport (our laboratory facilities are located at the LMU Chemistry Department).
  • Living in an international city with the possibility of several social activities.
  • LMU Munich is an equal opportunity employer and is committed to enhancing the diversity of its faculty. We therefore actively promote gender equality.
  • The position is funded by the ERC Starting Grant of INPERSPACE for one year, and a potential extension to the second year.

Also possible in a part-time capacity.

People with disabilities who are equally as qualified as other applicants will receive preferential treatment.


Prospective candidates are required to submit a complete set of application documents, which includes:

  • A research statement highlighting how the candidate aligns with the project tasks (a maximum length of two pages),
  • A CV and a copy of their PhD transcript,
  • A summary of the 3 key publications giving details of contributions (a maximum length of one page),
  • The contact information of the three referees,

to Shortlisted candidates will be notified via email to schedule an interview.

Where knowledge is everything.
