Open Positions

The Young Investigator Group Perovskite Tandem Solar Cells is looking for:

PhD student (m/f) within HI-SCORE research school - Advancing inorganic perovskite compositions for highly efficient top-cells in tandem devices


The Young Investigator Group Perovskite Tandem Solar Cells has recently published record efficiencies for perovskite/silicon tandem solar cells. The aim of the group is the further optimization of the fascinating class of perovskite/silicon tandem solar cells.


The new Helmholtz Innovation Lab HySPRINT and the Young Investigator Group Perovskite Tandem Solar Cells aims at developing high efficiency perovskite solar cells processed via vacuum-based methods. The announced PhD position is embedded in the broad HZB infrastructure offering the opportunity to contribute to third party projects, including industrial partners.


Topic of the doctoral thesis: Development and optimization of vapor deposited perovskite solar cells



  • Development and optimization of inorganic perovskite solar cells
  • Develop detailed understanding of loss mechanisms by quantifying bulk and interface recombination
  • Implement optimized inorganic top-cells into tandem devices



  • Highly motivated candidate with completed Master in Physics, Materials Sciences, Chemistry, or Electrical Engineering,
  • Sound knowledge in photovoltaics as well as solid state, organic and inorganic semiconductor physics
  • Experience with solution processing of perovskite solar cells is advantageous
  • Ability to work in a team with a problem-oriented approach to scientific work, commitment, dedication to experimental work and a high level of self-reliance
  • Willingness to present and publish scientific results at project meetings, national and international conferences as well as in scientific journals
  • Willingness to work part of the time in Israel
  • Very good English skills
