Small-molecule and polymeric solar cells: materials and devices (A. Abbotto, C. M. Mari, R. Ruffo)


This research line focuses on the fabrication and characterization of organic materials and devices for thin film photovoltaics. Materials include low bandgap semiconducting polymers and small-molecules. The design is based on heteroaromatic-based donor-acceptor conjugated systems for tuning of chemical, optical, electrochemical, and photovoltaic parameters. The semiconducting materials are combined with fullerene (e.g., PCBM) derivatives in bulk heterojunction photovoltaic cells.

Thanks to the recent grant from University of Milano-Bicocca this activity will be completed with the fabrication and characterization of organic solar cells.
This activity is performed in collaboration with leading groups in the field of solar cells (CNR-Bologna and Perugia).
