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. CHOSE is distributed across several laboratories, both within the University Campus of Tor Vergata and the Technopole Tiburtino. The latter consists of a 400 square meter laboratory that houses equipment for the fabrication and characterization of organic, hybrid, dye sensitized and perovskite photovoltaic cells, modules and panels and 150 square meters of office space for the incubation of spin-offs generated from research at CHOSE. The other laboratories, totalling roughly 300 square meters in extension, are located within different departments of Tor Vergata. At CHOSE there work more than 30 researchers including graduate students, postdocs and staff. CHOSE has also many collaborations at the regional, national and international levels.

The main objectives of CHOSE consist in the development of fabrication processes for organic and hybrid organic / inorganic solar devices, the definition of a process for the industrialization of these innovative photovoltaic technologies, the technological transfer of these and the development of photovoltaic applications in collaboration with companies at both the domestic and international level.

CHOSE also proposes itself as a reference point for photovoltaic technologies and their applications. In particular, in order to develop specific knowledge within the fields of both conventional and innovative photovoltaics and to prepare profiles of workers that are able to operate over the whole photovoltaic value chain, CHOSE manages a Masters degree course on "Photovoltaic Engineering" and an International School called ISOPHOS dedicated to PhD students and researchers.



Il Polo Solare Organico - Regione Lazio vince i
"Sette Green Awards" del Corriere della Sera

Milano, 1 Dicembre 2015
Dopo un lungo viaggio all’interno della nostra penisola nel mondo dei laboratori di ricerca, delle istituzioni e delle aziende per raccontare le eccellenze tricolori e i loro progetti sul fronte della sostenibilità, una giuria, presieduta dal professore di Economia Ambientale all'Università Bocconi Francesco Bertolini, ha consegnato i "Sette Green Awards" al Polo Solare Organico e ad altri due centri di ricerca.
I "Sette Green Awards" sono gli Oscar dell'ambiente delle pagine verdi del magazine del Corriere della Sera e premiano le eccellenze all'interno dei nostri poli universitari, emblema delle tante realtà italiane che si propongono di rinnovare il Paese e cambiare il futuro del pianeta.

Sun Trip 2015


Antonio De Chiara ha concluso in nona posizione su 25 partecipanti il Sun Trip 2015. Primo italiano a partecipare e concludere con successo il Sun Trip. Ha viaggiato, con la sua bici tandem solare, in 10 paesi differenti totalizzando 7000km in soli 54 giorni, scoprendo paesaggi inediti ,incontrando locali e spiegando cosa significhi energia solare e viaggiare liberamente grazie al sole.
Ulteriori 5000km percorsi da Milano a Berlino e ritorno a Salerno per un totale di 12000km ,3 mesi di viaggio effettivi, 5 mesi su strada.

Breaking news: CHOSE push the record of Perovskite module efficiency up to 13%

Researchers of CHOSE fabricated a Perovskite module on 10cm2 active area with a record efficiency of 13%. The results of the work have been published on Progress in Photovoltaics.

We fabricated monolithic solid state modules based on organometal CH3NH3PbI3 and CH3NH3PbI3-xClx perovskites using poly-(3-hexylthiophene) and Spiro-OMeTAD as hole transport materials (HTMs). In particular, we developed innovative and scalable patterning procedures to minimize the series resistance at the integrated series-interconnections. By using these optimization steps, we reached a maximum conversion efficiency of 8.2% under AM1.5G at 1 Sun illumination conditions using the CH3NH3PbI3-xClx perovskite and the poly-(3-hexylthiophene) as HTM. Finally, we investigated the double-step deposition of CH3NH3PbI3 using the Spiro-OMeTAD, reaching a maximum conversion efficiency on active area (10.08 cm2) equal to 13.0% (9.1% on aperture area) under AM1.5G at 1 Sun illumination conditions. This remarkable result represents the highest PCE value reached for the perovskite solar modules.
