Il Polo Solare Organico della Regione Lazio (CHOSE) è nato nel 2006 dalla volontà della Regione Lazio e dell'Università degli Studi di Roma Tor Vergata di creare un centro di eccellenza nel settore del fotovoltaico di nuova generazione.
CHOSE has been invited to present the results of its research on graphene-perovskite modules at the Tallinn Digital Summit.

On the importance of ferroelectric domains for the performance of perovskite solar cells
The effect of ferroelectric polarization patterns in MAPbI3 on JV characteristics has been analyzed. We discuss models for the polarization orientation pattern and magnitude of the ferroelectric domains. Simulations performed on real patterns show that the presence of ordered ferroelectric domains, even with a weak characteristic polarization magnitude enhances the power conversion efficiencies and are mandatory to reproduce the experimental J-V characteristics.
Results have been published on Nano Energy 48, pp. 20-26.
Fully laser processed Perovskite Solar Cell modules with 95% Aperture Ratio
Laser patterning has been applied to realize Perovskite solar modules with a ratio between active and total substrate area of 95% and an efficiency of 9.3%. These values are new records for large area (14.5 cm2) fully laser processed perovskite devices. This work signs a forward step to the industrialization of perovskite based solar technology. Results have been published on IEEE Journal of Photovoltaics DOI: 10.1109/JPHOTOV.2017.2732223
Graphene-Perovskite Solar module with efficiency 12.6% on 50 cm2
Graphene interface engineering (GIE) is proposed as an effective way to boost efficiency in Perovskite solar cells and modules.
A record efficiency of 12.6% on 50 cm2 module active area has been achieved by introduce Graphene in the mesoporous TiO2
and lithium neutralized graphene oxide (GO-Li) at the mTiO2/perovskite.
Results have been published on ACS Energy Lett. 2017, 2, 279−287

We fabricated the first perovskite-based monolithic series-type module showing very promising results in terms of the power conversion efficiency, the reproducibility of the fabrication process and long-term stability.
We fabricated perovskite based solar cells using CH3NH3PbI3-xClx with different hole transporting materials such as Spiro-OMeTAD and P3HT.
We fabricated the first solid state dye solar cell (SDSC) module using poly(3-hexilthiophene) (P3HT) as Hole Transport Material for the dye regeneration process.
Fully sprayed polymer solar cell modules open the way to bring Photovoltaics nominally everywhere, thanks to spray coating conformability to virtually any kind of substrate.
We have demonstrated the feasibility of the fabrication of a photovoltaic greenhouse roof by using techniques based on solution processing (spray coating and screen printing).
