Fixed term contract of 2 years, with possibility for extension

Your mission

Your main mission will be to develop high-efficiency photovoltaic technologies based on metal halide perovskite materials, in particular perovskite-on-silicon tandem solar cells. More specifically, your role will be to develop thin-film manufacturing processes that enable to scale-up the dimensions of perovskite solar cells. You will contribute to academic and industrial projects aiming to make perovskite solar cells and modules viable industrial products.

Your responsibilities

  • Produce perovskite solar cells using various solution- and vacuum-based thin-film deposition methods (thermal evaporation, sputtering, atomic layer deposition, spin coating, blade coating, etc.), in some cases using gloveboxes
  • Develop (solution-based) deposition methods to scale-up the active area of perovskite solar cells towards industry standards
  • Identify and troubleshoot performance-loss mechanisms affecting perovskite devices using various optoelectronic and microstructural characterization methods
  • Ensure processes reproducibility and bring the performance and stability of perovskite solar cells beyond the state-of-the-art
  • Promote and reinforce CSEM’s position through patents, publications, and presentations at conferences

Your profile


  • Master or PhD degree in physics, chemistry, microengineering, material sciences, or equivalent with a strong background in solid-state physics
  • Proven track record in the fabrication and characterization of solar cells (PhD or master thesis)
  • Expertise in the development of deposition methods to scale-up the dimensions of perovskite solar cells
  • Experience in the photovoltaic or thin-film industry considered as a plus
  • Skills in scientific programming (LabView, Python, etc.)
  • Professional proficiency in English (oral and written)

Interpersonal skills

  • Open-minded, creative, and result-oriented mindset
  • Highly motivated, eager to learn with a strong sense of ownership
  • Team player with good communication skills to interact constructively with colleagues and partners
  • Natural curiosity and ability to work on multidisciplinary projects
