Job description:

The rise of perovskite thin-film solar cells in recent years has opened up an exciting route to advance the power conversion efficiency of established photovoltaic technologies. For the first time, a wide bandgap thin-film PV technology is available at low cost that can be combined with established low bandgap semiconductors, such as crystalline Si and CIGS thin-films, in a multijunction module architecture with the potential of surpassing the efficiencies of 30%. However, to date several key scientific and technological challenges still need to be overcome to harvest this potential. One of these challenges is to improve the light management and energy yield of perovskite-based multijunction PV. 

This PhD project will design, fabricate and implement novel light management concepts and device architectures for semitransparent perovskite top solar cells for application in tandem photovoltaics. The project encompasses the simulation-based optimization towards the energy yield as well as the experimental prototyping. In addition, the capabilities of the EYCalc software platform will be extended by adapting machine learning methods."

The thesis will be conducted within the perovskite PV taskforce at KIT, which combines the expertise and equipment of several research groups at KIT. For the fabrication and prototyping of solution-processed perovskite solar cells a broad fabrication and characterization platform will be accessible via the involved institutes, the Light Technology Institute (LTI) and the Institute of Microstructure Technology (IMT). The scientific results will be published in peer-reviewed international journals and presented at international conferences. The thorough supervision and close collaboration within an interdisciplinary team will support the PhD candidate.

This research center is part of the Helmholtz Association of German Research Centers. With more than 42,000 employees and an annual budget of over € 5 billion, the Helmholtz Association is Germany's largest scientific organisation.
