Annual Scientific Report 2015

Abstract

The research on materials for energy and bio-applications are at the central core of our research. Since the group formation in 2006, our particular interest has been the development of third generation solar cells ( DSSC, OPV, QDSC and Perovskite materials) and the detailed study of the interfacial charge transfer reactions that limit the efficiency on these novel generation of solar cells. On the other hand, we are devoted also to the development and study of novel fluorescence semiconductor materials for biomedical applications that advance on the application of nano-science to medicine.

Topics addressed

• Synthesis and characterization of organic semiconductor molecules
• Dye-sensitized solar cells
• Perovskite solar cells
