ABOUT US


The Centre for Hybrid and Organic Solar Energy (CHOSE) was founded in 2006 from the will of the Lazio Region and the University of Rome Tor Vergata to create a center of excellence in the field of next-generation photovoltaics.

PROGETTO DI COLLABORAZIONE CON GSF

Aggiornamenti sui progressi della nostra collaborazione con Global Solar Fund (GSF) con cui stiamo sviluppando un nuovo metodo di coating.

"La ricerca e i test eseguiti hanno confermato le nostre ipotesi: una riduzione della temperatura indotta dal "coating" da 1 fino a 5° C con conseguente aumento della resa del pannello e quindi della produzione di energia. Terminata questa prima fase sperimentale del nostro progetto, ora possiamo passare ad ulteriori test sui nostri impianti con l’obiettivo di validare i dati registrati in laboratorio nei mesi più caldi."

FUTURE ENERGY - EXPO ASTANA 2017

CHOSE BETWEEN THE EXCELLENCES OF THE ITALIAN PAVILION

Another prestigious goal for CHOSE, just back from the international scene. It is the result of the presence of CHOSE at the EXPO dedicated to the future of energy, housed in Astana, capital of Kazakhstan, from 10 July to 10 September 2017.

FUTURE ENERGY - EXPO ASTANA 2017

In order to this important event, the first one for an Asian country, in the frame of the very suggestive setting of the italian pavilion designed by the architect Paolo Desideri Team, the Centre for Hybrid and Organic Solar Energy of the University of Rome "Tor Vergata" has been selected by the Lazio Region to represent one of the excellence more in line with strategic actions aimed at ecological sustainability.

PEROVSKITE SOLAR MODULES

Perovskite Solar Modules with 95% Aperture Ratio

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

Graphene-Perovskite Solar module with efficiency 12.6%

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
