Advanced Optics and Materials for Next Generation Photovoltaics
Our group researches the interaction between light and structured matter for the purpose of engineering novel optical concepts and nanophotonic materials for next generation photovoltaics. The photovoltaic technologies in focus of our studies are perovskite thin-film solar cells and perovskite based multijuntion solar cells. Our work involves the fabrication, characterization, simulation and understanding of the device physics of perovskite photovoltaics.
We are looking for highly motivated students interested in the areas of optics/photonics and thin-film photovoltaics. Three categories of positions are offered:
- Ph.D. thesis
- Bachelor/Master thesis
- Internships (min. 4 months)
If you are interested, contact us via mail. Please describe your interests and background. A CV, transcript of records and list of recommendations are highly appreciated.

02.10.2019 - Doctoral student Saba Gharibzadeh from the Institute of Microstructure Technology (IMT) received the best poster award at the International Conference on Perovskite Solar Cells and Optoelectronics in Lausanne (Switzerland). The award was given for her poster on “Record Open Circuit Voltage in High Efficiency Wide-Bandgap Perovskite Solar Cells” by Prof. M. Graetzel.
The Perovskite-Photovoltaics White Paper by the European Perovskite Initiative (EPKI) aims to raise the awareness of perovskite-based photovoltaics with governments, politicians, investors, industries, to support and initiate new generation Perovskite-PV industrial initiatives, and to facilitate joint-research programs and synergies amongst its members. Dr. Ulrich W. Paetzold, coordinator of the Taskforce Perovskite Photovoltaics at KIT, is one of the authors of this endeavour.
