Description, responsibilities and tasks

The PhD-candidate will survey relevant literature, plan and execute the experimental work and disseminate the results. In detail as follows:

  • Deposition of thin solid state semiconductor films in a modern wet-chemistry lab. Requires the use of essential lab ware, chemical processing equipment and high precision analytical equipment.
  • Characterization of semiconductor thin films. Requires using a range of techniques (microscopies, spectroscopies, diffractometry, profiling and mapping) and understanding their benefits and limitations. 
  • Characterization of solar cells. Requires using a range of techniques (current-voltage scans, spectral sensitivity, thermal dependence of direct current and capacitive response), knowledge of standard testing conditions.
  • Presentation of the results, verbally and graphically. Requires the ability to analyze and summarize the results and disseminate for a target audience, and impeccable formal communication skills.
  • Publishing of the findings. Requires the development of the knowledge of academic peer-review system and academic writing skills.


  • Master degree in the field of Chemistry, Chemical Technology, Materials Technology, Physics, and related.
  • First-hand experience in materials research, i.e. preparation of thin films and/or use of related characterization methods and analysis.
  • Excellent understanding of semiconductor and photovoltaics technology and research is favored.
  • Strong analytical thinking, fluent in English (both written and oral).
  • Competence in using data analysis and graphing software such as Microsoft Office (Word, Excel and PowerPoint), Origin.
