Annamaria Petrozza was born in Matera (Italy) in 1979. She was awarded a Master of Science in Electronic Engineering (emphasis on Devices, design and modelling) at Ecole Supèrieure d’Electricité (Paris, France) in 2003 under the T.I.M.E. (Top Industrial Manager in Europe) program. In 2004 she got a Master degree in Electronic Engineering (emphasis on Optoelectronics) at Politecnico of Milan with a thesis carried out at the Cavendish Laboratory of the University of Cambridge (UK) on the optical characterisation of a class of organic semiconductors with a supramolecular architecture for Organic Light Emitting Diodes. The research work was under the supervision of Prof. C. Cacialli and Prof. C. Silva. In 2008 she received her PhD in Physics from the University of Cambridge (UK) with a thesis on the study of optoelectronic processes at organic and hybrid semiconductors interfaces under the supervision of Dr. J.S. Kim and Prof Sir R.H. Friend. From July 2008 to December 2009 she worked as research scientist at the Sharp Laboratories of Europe, Ltd on the development of new market competitive solar cell technologies (Dye Sensitized Solar cells/Colloidal Quantum Dots Sensitized Solar cells). Her main tasks were to establish key needs of PV market, write research proposals to submit to the Sharp Business Group, and design and implement experiments. Since January 2010 she has a Team Leader position at the Center for Nano Science and Technology -IIT@POLIMI. She is in charge of the development of photovoltaic devices and their characterization by time-resolved and cw Photoinduced Absorption Spectroscopy, Time-resolved Photoluminescence and electrical measurements. Her research work mainly aims to shed light on interfacial optoelectronic mechanisms, which are fundamental for the optimization of operational processes, with the goal of improving device efficiency and stability.
The research activities are mainly focused on the investigation of the physics behind low cost "future generation" photovoltaic concepts and on the development of associated optoelectronic devices.
The research group she leads is active in fundamental studies on light harvesting and charge generation processes, charge transport and recombination processes at organic and hybrid interfaces, whilst improving the state-of-the-art device concepts in terms of absolute performance.
Main systems under investigation:
· Dye-sensitized Solar cells
· Nanostructured Polymer/Oxide Solar cells
· Fully organic solar cells
. Perovskites solar cells
Our experiments include:
· Time resolved (fs to ms) and quasi-cw photoinduced absorption and photoluminescence spectroscopy.
· Device fabrication and test through microscopic and electronic characterization techniques - AFM, current/voltage measurements under simulated sun light and deriving the photovoltaic action spectra, transient photovoltage/photocurrent measurements.
