Jobbeschreibung

Postdoc (f/m/d) Development of All-Perovskite Triple Junction Solar Cells

Reference No.: SE 2025/22

Helmholtz-Zentrum Berlin (HZB) is a research center for fundamental and applied research in the field of energy materials. HZB operates advanced analytics, such as the large synchrotron facility BESSY II. For the next generation photovoltaics (PV), HZB performs materials research and device development up to the industrial level. The department of perovskite tandem solar cells develops metal halide perovskite solar cells and achieved several world records for perovskite-silicon and perovskite-CIGS tandem solar cells in the past years. Recently, new projects started with the goal to advance all-perovskite tandem solar cells. Here, we look for investigating fundamental material properties, understanding charge carrier dynamics, new device configurations, high operational stability, and large area scaling.With this new postdoc position, we aim to advance our research on multi-junction solar cells and develop perovskite-based triple-junction devices. To reach our ambitious goals, we are looking for highly motivated and experienced scientists/postdocs in the field of perovskite solar cells, who are eager to work in our international and multidisciplinary group.
