As PVcomB, we develop thin-film photovoltaics and related technologies at Helmholtz-Zentrum Berlin in cooperation with industry. We thus ensure innova­tive technology transfer through industry-oriented research projects as well as the education and training of PV specialists.
You will support us as a post-doctoral scientist in the Photovoltaics to Fuels Technology (PVFT) group. The focus of our group is on the development of device concepts that integrate photovoltaic devices with electrolysers to produce fuels such as hydro­gen from solar energy. Therefore, an exciting and interdisciplinary position awaits you!


  • Design, optimisation and energy analysis of electrochemical hydrogen compression (EHC) integration with electrolysers
  • Develop multi-physics-based 3-D computational fluid dynamic models for (EHC)- integrated electrolysers for hydrogen generation
  • Experimental validation of the models and characterisation of the devices
  • Analyse, present and disseminate experimental results in peer reviewed journals and at conferences


  • You have completed a PhD in Chemistry, Physical Chemistry, Chemical Engineering, Physics, Electrical Engineering or a closely related field
  • A sound background knowledge in electro­chemistry; additional basic knowledge of thermo­dynamics is desirable
  • Proven experience in multi-physics-based modelling for computational fluid dynamics using COMSOL, ANSYS or related tools during your PhD research or your latest position
  • Prior hands on experience in the assembly and characterization (including gas quantification) of electrolysers and/or fuel-cells is mandatory
  • Excellent skills in programming with Python, C++, Matlab or equivalent software
  • Fluent spoken and written German and English is mandatory

What we offer

  • The opportunity to work in a renowned non-university research institution in Berlin
