Internship | Perovskite solar cell development on charge transport layers and absorber

About this position

Perovskite solar cells belong to the family of thin film photovoltaic technologies. They are based on a thin layer of hybrid metal halide perovskite as absorber, in the order of a micron thick, which converts the solar irradiation to photo-generated current. One of the advantages of perovskite photovoltaics is that the layers constituting the cell can be solution processed at relatively low temperatures.

What will be your role?

The tasks for the intern in this project are:

  • Optimizing the ETL in order to reduce the inherent hysteresis and improve the open circuit voltage in NIP device structures. This includes selection of the correct ETL material, optimization of dopants/additives in the ETL and implementation of an interface layer between ETL and perovskite absorber;
  • Implementation of a perovskite absorber that will be suited for single junction applications, with bandgap optimized towards 1.5 eV.

The focus on perovskite processing will initially be on state of the art solvent systems at small scale with a view towards environmentally benign solvents. Solar cell and layer characterization using electrical, morphological and spectroscopic techniques will be part of the daily work.

What we expect from you

  • A background in physics, chemistry, material science or electrical engineering.
  • High motivation, with a curious nature and a taste for problem-solving.
  • Ability to work autonomously and good social skills to interact with your team and get the information you need from the most knowledgeable people around you.
  • The duration of this project should be minimum six months, preferably in the MSc phase of your study.
  • You need to be affiliated with a university during the internship for eligibility!

The selection process

After the first CV selection, the application process will be conducted by the concerning department. TNO will provide a suitable internship agreement. If you have any questions about this vacancy, you can contact the contact person mentioned below.

For this internship vacancy it is required that the AIVD issues a security clearance (VGB) after conducting a security screening. Take into account that this process may take about 8 weeks. If you have been abroad for more than 6 consecutive months, or if you do not have the Dutch nationality, it may take longer. Read more about security screening on the AIVD website.

Important to be aware of before applying:

  • Before the start of the internship, the internship agreement from TNO needs to be signed. For students at a college or university based in the Netherlands, TNO uses the UNL-template (supplemented with a number of specific agreements from TNO). For students of foreign and MBO educational institutions, the TNO internship agreement applies. TNO does not sign any other internship agreements.
  • Before the start of the internship, the educational institution will need to confirm in writing that:
    • 1) you are enrolled at the educational institution during the internship, and;
    • 2) the internship takes place as part of the programme of the study.
  • The confirmation of educational institution takes place by signing the UNL template or forms prepared by TNO.
  • Interns at TNO must be in possession of a Dutch residential address at the start of the internship. Performance of internship activities from abroad is not possible.
