Spin Effects in Organic Solar Cells
The goal of this project is to provide an estimate of how much spin effects can be used to investigate the photophysics of organic solar cells as well as how much they influence and can enhance the performance of Organic Solar Cells (OSCs). In order to accomplish this task, the focus will be directed towards three main aspects: (1) the doping of organic semiconductors, (2) the photophysics of organic solar cells, (3) the morphology of the active layers.
The whole analysis will involve the fabrication of the studied samples through the use thermal evaporation under vacuum. Thermal evaporation is a well-suited technique to fabricate samples with a high reproducibility thanks to its high control over the composition and thickness of the individual thin layers and the possibility to tailor Fermi level and interfaces using doping. The project is likely to include various secondments to be trained in advanced Electron Paramagnetic Resonance (EPR) spectroscopies and thin film processing techniques. Studied samples will be fabricated using both commercially-available molecules and recently-synthetized molecules. The overall analysis aims to pave the way to the use of spin effects in OSCs.
Alberto Privitera received his PhD in Material Science at the University of Padova. The title of his PhD thesis is “Development and characterization of nanostructured materials for organic and hybrid solar cells”. Currently, he is a postdoc at the Oxford University in the Advanced and Functional Materials and Devices Group which is run by Prof. Moritz Riede. His research efforts are directed towards the study of the photophysical processes within organic solar cells (OSCs) with a particular focus on the role of the electronic spin.
