Singlet and triplet electronic excitations in polar molecules: Impact on charge separation at organic interfaces
The main scientific objectives of the project are to understand and tune the spin dependent mechanisms involved in light harvesting within organic semiconductors (OSC) as a pathway to improve the efficiency of charge generation and reduce recombination, and to enhance the performance and lifetime of these devices.
The theoretical group in Mons supervises a work package dedicated to the exploitation of spin processes for improving the solar cell performance via reducing geminate and nongeminate losses of the spin-dependent interfacial charge-transfer states and utilizing triplet migration, singlet fission and triplet–triplet annihilation as pathways to increase the light harvesting in OSCs. To this end, the researcher will use a combined multiscale modeling approach encompassing force-field molecular dynamics simulations, quantum-chemical calculations and the solving of model Hamiltonians, in close relation to experimental investigations performed by partners in the consortium.
The group is part of the Centre for Innovation and Research on Materials and Polymers at UMONS and was awarded the 2003 Descartes Prize of the European Union for excellence in academic-industrial collaboration.
Giacomo Londi received his Master Degree in Chemical Sciences in the October 2015 at the University of Florence (Italy). He carried out his Master's training within the "Laboratory of Molecular Magnetism" (LAMM) research group at the Department of Chemistry "Ugo Schiff", in Sesto Fiorentino (Italy). His dissertation thesis dealt with ab initio periodic calculations based on the Density Functional Theory, in order to study the electronic and magnetic properties of a spin crossover system. After the degree and throughout the 2016, he kept on collaborating with the LAMM computational group. In the February 2017 he joined the "Laboratory for Chemistry of Novel Materials" at the University of Mons (Belgium). Under the supervision of Prof. David Beljonne, he is currently a phD student involved in the SEPOMO project.
