Riccardo Riccitelli achieved the M.Eng. degree cum laude on Telecommunications Engineering at University of Rome, “Tor Vergata”. He received in 2008 in the same university the PhD degree in System Engineering. His graduate work has been focused on the realization and characterization of vacuum nano- and micro-electronic devices based on carbon nanotube (CNT) structures.

Currently, he is responsible for the design and development of the Pilot Production Line in Dyepower, a R&D Consortium founded with the purpose of realizing the first line for the fabrication of building integrated photovoltaic (BIPV) façades made by organic photovoltaic technology. He also coordinates the Product Development team with the aim of designing the BIPV device and defining the potential applications.

He collaborates with “C.H.O.S.E.”, the Center of Lazio District for the development and the research of the organic and the hybrid devices in the field of photovoltaic technologies. He is charter member and Executive President of DYERS s.r.l. a spin-off company of University of Rome, "Tor Vergata", involved in the materials production and measurement systems integration in the field of organic electronics. 

He is collaborating with the organization of the association "FREEnergy" and he is one of the charter members of ISOPHOS: International School on Organic Photovoltaics held in Ventotene Island (Italy).

IMPORTANCE OF FERROELECTRIC DOMAINS

importance of ferroelectric domains for the performance of perovskite solar cells

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.

A Crystal Engineering approach for perovskite solar cells and modules fabrication out of the glove box

we fabricated high efficiency perovskite solar cells (PSC) and perovskite solar modules (PSM) utilizing several Hole Transport Layers (HTLs). The results show that the Crystal Engineering approach remarkably improved the device performance reaching a power conversion efficiency of 17%, 16.8% and 7% for spiro-OMeTAD, P3HT and HTL free, respectively.

Photoelectrochemical and spectrophotometric studies on dye-sensitized solar cells (dscs) and stable modules (dscms) based on natural apocarotenoids pigments

We present a study on dye-sensitized solar cells (DSCs) and we fabricate dye-sensitized solar modules (DSCMs) based on natural apocarotenoids extracted from the achiote's seeds (annatto). Use of less polar solvent such as diethyl ether improves the bixin concentration in the annatto extract which, was employed as sensitizer in the devices.
