Tobias Abzieher joined NREL's Chemistry and Nanoscience Center in early 2021 as a postdoctoral researcher in David Moore's research group. His research focus is on the development of vapor-based deposition techniques for the fabrication of efficient vapor-processed perovskite solar cells. Tobias also is interested in the upscaling of perovskite technology, the use of perovskite-based materials for tandem applications, and the development of industrially applicable fabrication techniques. 

Tobias received his bachelor’s and master’s degrees in physics from the Karlsruhe Institute of Technology (KIT) in 2012 and 2014, respectively. After a research position with a focus on the investigation of kesterite solar cells at the Center for Solar Energy and Hydrogen Research Baden-Wuerttemberg, he continued his research as a doctorate candidate at the Light Technology Institute at KIT. He received his doctoral degree for his work on the development and investigation of efficient vacuum-processed perovskite solar solar cells in 2019. During this time, he also contributed to various other research topics including the development of inkjet-printed perovskite solar cells as well as solar modules and multi-junction solar cells—both in national and international research projects.
