Internship | Alkali doping of CIGS solar cells for perovskite-CIGS tandem applications

About this position

Tandem technology offers a realistic approach to increasing the efficiency of photovoltaic devices above the single-junction efficiency limit. From various tandem technologies, Perovskite-CIGS tandems represent an attractive, cost-effective, all-thin-film viable option. In such tandems, the bandgap of the bottom CIGS cell should be ~ 1.0-eV with an anticipated bandgap of the Perovskite cell of 1.6-1.7 eV. While for CIGS with higher bandgaps, efficiencies > 23% have been demonstrated, cells with ~1.0-eV bandgap only reach ~19%. The project focuses on optimization of RbF post-deposition treatment of CIGS absorber to boost the efficiency of CIGS cell for Perovskite-CIGS tandem applications.

What will be your role?

The purpose of this assignment is further optimization of RbF post-deposition treatment of the CIGS absorber. Within this project, you will learn how to apply and characterize CIGS solar cells, will be involved in designing the experiments, and perform experimental work to understand and further optimize the post-deposition treatment of CIGS absorbers.
You will be working closely with experienced process engineers and PV researchers in the framework of the H2020 project PERCISTAND.

What we expect from you

  • Be enthusiastic and eager to learn about photovoltaics;
  • Be interested in performing an experimental work and characterization;
  • Have good problem-solving skills;
  • Ability to work autonomously within a small team and good social skills to get the information you need;
  • A background in (applied) physics, chemistry, material science, or electrical engineering.

You need to be affiliated with a university during the internship for eligibility.
The duration of this internship is at least 6 months, ideally 9 months, preferably in the MSc phase of your study.
