The Graduate School "Materials for Solar Energy Conversion (MatSEC)" is looking for:

PhD-Scholarship Student (f/m)

Kennziffer: MatSEC 2016/6

The Graduate School “Materials for Solar Energy Conversion” (MatSEC) is a member of Dahlem Research School (DRS), which provides a structured graduate education at Freie University Berlin. MatSEC combines experiment and theory in the areas of material science, crystallography, solid state physics, solid state chemistry, and scientific computing to develop structure-property relations which allow for the design of custom-made materials for solar energy conversion.

Topic of the doctoral thesis:
Correlative microscopy and spectroscopy on halide perovskite solar cells

This project aims at the analysis of organic-metal-halide perovskite materials as absorber layers for solar cells.


Macroscopic phase analysis via infrared spectroscopy and transport properties will be conducted. The spectroscopy results will be correlated with corresponding spectra obtained by electron energy-loss spectroscopy in high-resolution, scanning transmission electron microscopy, which will give information on phase distributions with spatial resolutions of 10-20 nm. Microstructural, electrical, and optoelectronic properties of the organic-metal-halide perovskite thin films at the microscopic level will be measured by means of electron backscatter diffraction, electron-beam-induced current, and cathodoluminescence measurements.


  • Completed master’s degree in physics or materials science
  • Strong motivation in research
  • Good verbal and written communication skills in English

  • HZB grants PhD scholarship for the development of qualified junior scientists. The Phd scholarship is limited to 3 years. The amount of the PhD scholarship complies with the valid PhD scholarship allowances of DFG.

    We particularly welcome applications from women. Preference will be given to handicapped applicants provided equal suitability.

    Have we sparked your interest? Then we look forward to receiving your application by 31.01.2017
