Helmholtz-Zentrum Berlin für Materialien und Energie (HZB)
Helmholtz-Zentrum Berlin für Materialien und Energie (HZB) investigates and develops materials for a sustainable energy supply. For this purpose, we operate the synchrotron facility BESSY II as well as several core labs, which offer an enormous variety of analytical methods for investigating materials. The unique research environment at BESSY II is also attractive for external users from all over the world. With approx. 1,200 employees, the HZB is today one of the largest non-university research centres in Berlin. More information:
SCIENCE + CAREER + DIVERSITY = HZB
... is the formula for our successful human resources policy. We offer wide-ranging internal and external qualification opportunities for our employees, including special support for junior scientists. Our family-friendly workplace policy includes flexible working hours and telework arrangements. HZB values diversity as driver for successful scientific collaborative work and promotes a supportive working atmosphere for people from all backgrounds.
PhD Student (f/m/d) Perovskite/Silicon tandem solar cells – characterization and modeling for highest performance and energy yield
The young investigator group "Perovskite Tandem Solar Cells" has recently published two record efficiencies for perovskite/CIGS as well as perovskite/silicon tandem solar cells. The aim of the group is to further optimize this fascinating tandem technology by detailed understanding of the dominant loss mechanisms. With this announced PhD position, detailed optical and electrical characterization should help to improve the performance and energy yield of perovskite-based tandem solar cells.
The announced PhD position is embedded in the broad HZB infrastructure, including the Helmholtz Innovation Lab HySPRINT. Collaboration is planned with the Competence Centre Photovoltaics Berlin (PVcomB), especially with the group for Outdoor Performance Analysis at HZB and the 'Laboratory of photovoltaics and optoelectronics' at the University of Ljubljana in Slovenia. This collaboration offers the opportunity to bridge the gap between fundamental research and industrial applications.
Topic of the doctoral thesis: Perovskite/Silicon tandem solar cells – characterization and modeling for highest performance and energy yield.
The PhD student will be a member of the Graduate School "Hybrid Perovskites Solar Cells" (HyPerCells).
