Dr. César Omar Ramírez Quiroz
NICE Solar Energy, Schwaebisch Hall, Germany
Originally from México, and with a chemical engineering bachelor’s degree, César pursued his higher education at the Polytechnic Institute of Scientific Research and Technology in San Luis, Mexico. At the physics and advanced materials department, he gained my master’s degree for his work on the photo-physical secondary doping mechanisms of optoelectric thin films. His academic interest took him to spend almost two years at The University of Arizona (U of A), AZ, USA as a research and teacher assistant under the supervision of Prof. Neal Armstrong. During his professional stay at the U of A, he attempted to augment his technical training on thin films and photovoltaic (PV) technologies driving his professional career, through an awarded grant, to Friedrich Alexander University (FAU), in Germany. At FAU he worked on perovskite-based photovoltaics. Specifically, his main focus was to target high efficiencies through multi-junction solar cells. This work awarded César his PhD degree for his thesis entitled “Efficient perovskite tandem solar-cells: Structure, optimization, and novel concepts”, under the supervision of Prof. Christoph J. Brabec and Prof. Bernd Rech.
Academically, his research interests include the understanding of the interfacial dynamics between the selective layers and the photoactive material, light management for achieving highly infrared-transmissive layouts as top-cells, and numerous Nobel device designs for high-performance tandem devices.
