New fuel for Organic Solar Cells?

Researchers from CNST of IIT, in collaboration with Konarka and Politecnico di Milano, discovered a new mechanism at the heart of the physics governing Organic Solar Cells (OSC). Theoretical calculations predict efficiencies of up to 20% for OSC, but experimental evidence shows different results.

By studying a new class of promising materials, which recently brought OSC to the new record efficiency of 10%,  Grancini and co-authors found where the hidden energy may lie. They discovered that in such class of materials the conversion of light into electrical power happens via an ultrafast process, a mechanism which is different from what was expected and experimentally verified in other materials of common use in OSC.  This discovery could open a new point of view in the engineering of molecules and organic compounds for organic solar cells.

The study was published on Nature Materials (Nature Materials 12, 29–33 (2013) doi:10.1038/nmat3502).

Towards DESTINY

CNST joins DESTINY (Dye Sensitized Solar Cells with Enhanced Stability) European Project

Destiny
Destiny

Among the photovoltaic systems which promise low cost fabrication methods, hybrid solar cells (where metal oxides are interfaced to organic materials) are of great interest and dye-sensitized solar cells (DSSC) are a realistic option with market-appealing power conversion efficiencies above 12%. However, they still remain an interesting playground for scientists, engineers and technologists as many issues regarding the devices’ working processes still have to be fully unveiled. On top of this, long term stability is a crucial problem for the actual taking off of the technology.
