Paolo Mariani obtained the Master Degree in Physics at the University of Rome "La Sapienza" by defending a thesis on "Phase transitions and stochastic transitions in finite systems with short and long-range interactions" (, under the supervision of prof. A. Giansanti. Statistical mechanics was the main research field with particular attention to molecular dynamics, implemented by computational simulations. Then, he has oriented his scientific interest in applied research by attending the second-level professional master's programmes in Photovoltaics Engineering at University of Rome “Tor Vergata”. In April 2012, Paolo Mariani defended a thesis on “Analysis and optimization of production process of DSSC photovoltaic devices”, under the supervision of prof. F. Giannini. By virtue of this experience, he started working at Dyepower Consortium, where he was involved in the development of large-area DSSC (Dye Sensitized Solar Cell), from October 2011 to December 2015. From May 2013 to April 2014, he was research fellow in the Electronic Engineering Department of University of Rome "Tor Vergata". Research program was the identification, deposition and optimization of materials for the production of DSSC photovoltaic panels. In April 2018, Paolo Mariani got Ph.D. in Electronic Engineering (University of Rome “Tor Vergata”) defending a thesis on “Novel classes of Dye Sensitized Solar Modules”, under the supervision of prof. Aldo Di Carlo. From July 2018, he is a research fellow (postdoctoral) in the Electronic Engineering Department of University "Tor Vergata" within the C.H.O.S.E. lab.

Research Activity

The research activity of Paolo Mariani is focused on the development of hybrid organic/inorganic large area solar cell. Currently, he is involved in the Graphene Flagship Project as research fellow (postdoctoral) under the supervision of Prof. Aldo Di Carlo (University of Rome Tor Vergata). Main topic is the study, the optimization and the characterization of Photovoltaic Modules Graphene/Perovskite. In particular, he studies both the replacement of metal counter-electrode in PSC (Perovskite Solar Cell) technology with carbon-graphene pastes and the overall encapsulation strategies. Moreover, he investigates the metallization process in order to realize metal grids for PSMs (Perovskite Solar Modules) also in the perspective of applying them in perovskite silicon tandem solar cell. All these explorations are based on original combination of GRMS (Graphene and Related Materials) ad hoc developed by IIT (Istituto Italiano di Tecnologia). He is  also involved in the realization of Perovskite Photovoltaic‐Thermoelectric Hybrid Devices in collaboration with University of Milano Bicocca and with MIT. During his PhD, the activity has been focusing on the realization and characterization of novel classes of Dye-Sensitized Solar Modules (DSSMs) involving 2D materials or flexible substrates. Key words of him research are: "deposition techniques", "up-scaling", “large-area devices”, "2D materials" and "stability".
