Doctoral Candidate (Ph.D student) in the field of photovoltaics - Defect physics of semiconductors (M/F)

University of Luxembourg

Luxembourg, Luxembourg

Defects have a strong influence on the performance of absorber materials for solar cells. The PhD candidate will perform calculations on the spectroscopic signatures of point defects in the thin-film solar cell materials Cu(In,Ga)S2 and Cu(In,Ga)Se2. This will require the use of existing ab-initio codes based on density-functional theory and on many-body perturbation theory. It will also involve the development of “second principles” methods such as tight-binding (fitted to ab-initio methods in small supercells). A background in theoretical solid state physics is desirable.


  • Use and Development of electronic structure methods for defect calculations
  • Performing research on the influence of defects on the performance of solar cell materials
  • Publications in international journals and conferences
  • Writing a thesis
  • Occasional teaching and public outreach

  • Excellent Masters in physics, computational materials science, quantum chemistry, or similar
  • Self-motivated, committed and curious
  • Creative and independent thinker
  • Very good knowledge of English
  • Good oral communicator


  • An exciting topic in the context of renewable energies and computational materials science
  • A friendly international team and environment
  • Modern, and well equipped labs
