FIRB Futuro in Ricerca 2008

Bulk heterojunctions of nanostructured molecular thin films for high efficiency flexible photovoltaic cells.

The network wants to develop new set of materials, new synthesis approaches, new thin film processes, new complex material architectures and new modeling approaches to find out improved energy conversion efficiency in thin film bulk heterojunctions photovoltaic (PV) cells with respect to the already reported data. In the case of organic solar cells 5.15 % efficiency on an area larger than 1 cm2 have been demonstrated.

Also the network will be devoted to maximize the competitiveness in terms of efficiency/cost ratio, mainly by developing all-solution processes.
Fully organic and hybrid organic-inorganic thin film architectures will be realized. The new synthesis and molecular systems refer to:
i. soluble derivatized single wall carbon nanotubes (SWCNTs) enclosing novel photoactive units and bearing light harvesting antennas;
ii. nanoparticles of inorganic semiconductors functionalized by an organic shell.




On the occasion of Solis Project annual meeting in Padova, two seminars will be held by Roberto Improta and Bruno Pignataro.
