The Institute of Physics (IoP) of the Faculty of Science (FNWI) has a postdoctoral position available in the Photovoltaics and Soft Matter groups of the WZI at the University of Amsterdam.

The aim of the project is to investigate perovskite nanocrystal layers for efficient energy conversion. Recently synthesized all-inorganic perovskite nanocrystals combine advantages of hybrid perovskites with bandgap tunability and surface functionalization. We take advantage of these recent breakthroughs to assemble perovskite nanocrystal films as tunable quantum solids for PV applications.

Quantum solids (QS), created by controlled and ordered aggregation of quantum dots, represent an exciting new class of materials with tremendous potential for optoelectronic applications. Their electronic structure features a unique combination of two components – that of the quantum-confined electronic states within the quantum dots (QDs) superimposed on the “band structure” arising from the coupled, regular arrangement of the QDs, analogous to the band structure of atomic solids. So far, however, this has remained a largely theoretical concept. We will explore realization of such tailored QS using all-inorganic perovskite nanocrystals that have been synthesized very recently. Using the system CsPbX with X the halide element, this is uniquely possible since the elemental composition of both shell and core is the same (CsPbX3 for perovskite core, and Cs4PbX6 for the insulating shell). The envisaged core-shell structure will open new routes to 1. Tailor the inter-QD separation and coupling within the square super-lattice and 2. Realize continuous “in-situ” tuning of QS electronic states through in-situ expansion of the QD core at the expense of the shell. Eventually, the shell can be completely transformed into perovskite, creating a solid thin semiconducting layer.

The work will be embedded in the lively research environment of the Van der Waals-Zeeman institute, where it will strengthen the recent collaborations between the colloidal and nanocrystal group of Prof. P. Schall and the Nano-Photovoltaics group of Prof. T. Gregorkiewicz . The work is further embedded in the excellent Solar Energy Research environment in Amsterdam, where groups of the Vrije Universiteit (VU), AMOLF, and the University of Amsterdam (UvA) collaborate. The successful candidate will work in an inspiring cross-disciplinary environment with diverse expertise in nanocrystal synthesis, assembly, and optoelectronic properties.


  • PhD degree in Physics, Chemistry or Chemical engineering;
  • experience in the following fields: nanocrystal synthesis or assembly, energy materials, photovoltaics;
  • good communication skills (English).


The full-time appointment will be on a temporary basis for a period of three years. The monthly gross salary will range between €2,640 and €4,166 (scale 10), based on a full-time appointment. We offer a pension scheme, a holiday allowance of 8% per year, an end-of-year bonus of 8,3% and flexible employment conditions. Conditions are based on the Collective Labour Agreement of Dutch Universities. Favourable tax agreements may apply to non-Dutch applicants.
