PhD Student (f/m/d) Tandem Perovskite and Silicon Solar Cells – characterization, modeling, stability

PhD Student (f/m/d) Tandem Perovskite and Silicon Solar Cells – characterization, modeling, stability
The doctoral theses will take place at three closely cooperating Institutes, in three working groups. We are looking for two PhDs.

In Berlin:
The mission of PVcomB is to support worldwide growth of thin-film photovoltaic technologies and products by providing top-level development and technology transfer. In co-operative R&D projects with academia and industry all relevant aspects of thin-film photovoltaics are addressed. The structure of PVcomB is unique in its combination of research & development with high-level education and training. The Thesis is hosted in the group Outdoor Performance Analysis.

The Young Investigator Group Perowskite Tandem Solar Cells is conducting on the organic-inorganic perovskite materials, which are one of the biggest surprises in solar cell research. In just six years, the efficiency of perovskite solar cells has increased five-fold; moreover, perovskite solar cells can be manufactured from solution and be cost-effectively printed on large areas in the future. The group holds the current world record in the highest efficiency of a tandem solar cell with Perovskite.

In Slovenia:
The strength of the ‘Laboratory of photovoltaics and optoelectronics’ at the University of Ljubljana (LPVO-UL) in Nano-optics, computer simulation und outdoor monitoring of solar devices supports this common project. With the HZB, a long lasting close colaboration is already set up.

1. Topic of the doctoral thesis: Perovskite silicon tandem solar device, characterization, modeling, stability
2. Topic of the doctoral thesis: Perovskite silicon tandem solar cells, outdoor device characterization and energy yield modeling

The PhD students will be a member of the Graduate School “Hybrid systems for electronics, optoelectronics and photovoltaics” (Hybrid4Energy).
