Scientific collaborator on perovskite/silicon tandem solar cells

Updated: about 2 months ago

The Ecole polytechnique fédérale de Lausanne (EPFL) is one of the most dynamic university campuses in Europe and ranks among the top 20 universities worldwide. The EPFL employs 6,000 people supporting the three main missions of the institutions: education, research and innovation. The EPFL campus offers an exceptional working environment at the heart of a community of 16,000 people, including over 10,000 students and 3,500 researchers from 120 different countries.


Your mission :
The Photovoltaics and Thin Film Electronics Laboratory of EPFL is a world-leading laboratory dedicated to solar cell research. PVLAB activities range from the deposition and characterisation of thin films, their incorporation in high efficiency devices (silicon heterojunction solar cells, silicon cells based on high temperature passivating contacts, perovskite-on-silicon tandem solar cells, detectors), the encapsulation of solar cells to form modules to grid integration aspects of photovoltaics.
The candidate will join the “Perovskite Cells for Tandem Applications” team, a key player in the field of perovskite-on-silicon tandem solar cells research. Her/his tasks will be to contribute to the development of perovskite-on-silicon tandem solar cells yielding high efficiencies. She/he should advance the lab expertise by bringing her/his own innovative ideas, experience and motivation.


Main duties and responsibilities include :
  • Deposition of thin film layers in gloveboxes using various techniques (thermal evaporation, sputtering, atomic layer deposition, spin coating),
  • Fabrication of perovskite top cells incorporated in high-efficiency perovskite-on-silicon tandem solar cells,
  • Identification of performance-loss mechanisms in tandem devices using various optoelectronic characterisation methods, including advanced spectroscopic methods,
  • Coordination of research activities with other PVLAB partners,
  • Supervision of undergraduate student projects and junior members of the lab.

Your profile :
  • PhD degree in Physics or Material Sciences,
  • Expertise in the fabrication and characterisation of high-efficiency perovskite-on-silicon tandem solar cells, with deep understanding of device physics aspects,
  • Hands-on experience in vapour-based deposition routes of metal halide perovskites,
  • Expertise in the optoelectronic characterisation of solar cells and their simulation,
  • Expertise in electro-optic spectroscopic characterisation of perovskite-based devices,
  • Hands-on experience in electron and scanning probe microscopy techniques,
  • High motivation, independency, ability to supervise the work of others, team spirit,
  • Full proficiency in English (including writing).
