The Advanced Materials for Optoelettronics (AMO) focus on the investigation of the physics behind low cost "future generation" photovoltaic concepts and on the development of associated optoelectronic devices, with a special emphasis on the role of interfacial optoelectronic mechanisms with the goal of improving device efficiency and stability.

AMO is active since 2010 in the Center for Nano Science and Technology @PoliMi (CNST) of the Italian Institute of Technology. From 2012 onwards the group core-business has been the investigation of solution processable perovskite semiconductors.  Unlike more widely studied inorganic semiconductors, metal halide perovskites have fluctuating ionic structures where tilting, distortions and polarizability of the lattice strongly affect the optoelectronic properties. This makes the reliability of perovskite based devices strongly dependent on the control of the structure-properties relationship of the active material and of its response to external stimuli, such as chemical interactions upon interface formation, electric field, light and environmental agents. We combine fundamental investigations on the materials properties with material processing, and with the design, fabrication and characterization of reliable and efficient optoelectronic devices to quickly deliver whole generation of perovskite-based optoelectronic devices.


AMO Group manage the following facilities: WETLAB2 (aka ARCOLab), which is fully dedicated to the perovskites based devices fabrication, and the optical labs, which include a fs-ms pump probe set-up, cw-photoinduced absorption set-up, time-resolved photoluminescence set-up (1.6 ps time resolution with Streak Camera detection system up to 900nm, 1ns time resolution with TCSPC detection system up to 1400nm), Electro-Absorption and Charge Modulation spectroscopy set-ups. They can all be coupled to confocal microscopes to add spatial resolution to our time resolved spectroscopic studies. The labs are also equipped with chambers for controlled atmosphere (vacuum, N) and temperature dependent (down to 4K) experiments are available. Spectro-photometer (200nm-2500nm) and Spectro-fluorimeter (300nm 1700nm) both coupled with an integrating sphere. Luckily, we are in a lively and multidisciplinary Center, which gives us fully access to Printing tools for device manufacturing, an Electrical Characterization Lab which is equipped with everything is needed for the full characterization of devices such as transistors, photodetectors, solar cells and photo-doctors; and a structural and morphological characterization lab which includes XRD, AFM, vibrational spectroscopy set-ups (Raman and IR), contact angle measurements.
