My research project focuses on fabrication of different TiO2 morphologies and their application in hybrid solar cells. In-depth analysis of physical processes like charge separation, transport and recombination should provide insight into fundamental working principles of next-generation solar cells. Limitations should be identified to infer pathways towards highly efficient hybrid devices. Design rules concerning the ideal morphology should be revealed and might be applicable also for fully organic solar cells.
The project is carried out in collaboration with the groups of Prof. Christina Scheu (LMU Munich), Prof. Thomas Bein (LMU Munich) and Prof. Judith MacManus-Driscoll (University of Cambridge).
