The course aims to address it from a global point of view that includes materials science, chemistry, physics the various spectroscopy techniques as a fundamental method for the study of chemical-physical processes and the basic properties of different natural and artificial materials. the the objectives of the course are many: 1. Understanding of the basic properties of organic and inorganic materials; 2. Understanding of the main spectroscopic techniques for investigating the atomic, electronic and vibrational structure of solids; 3. Understanding of major optical investigation techniques e spectroscopic for the analysis of materials and photovoltaic devices (UVVIS, Raman spectroscopy, Photoluminescence, Solved spectroscopy in Pump-Probe time); 4. Understanding - through examples - of physicochemical processes that occur as a result of the interaction with light. Static and dynamic processes
Course Prerequisites
Basic knowledge of physics and chemistry at the Bachelor degree level in scientific disciplines. Knowledge on basics of solid state physics is a plus.
Teaching Methods
Interactive lessons supported by PowerPoint projections (previously delivered to students). If possible, laboratory tours. The interaction stimulated and mediated by the teacher creates interesting points for discussion and allows to verify and level the knowledge useful for the understanding of some of the specialized topics covered in the course (in order to equalize the notions held by students from different master's degree courses such as Chemistry, Physics and Engineering)
Assessment Methods
The final evaluation includes an oral exam and a short written report. In the oral examination the topics dealt with during the luctres will be discussed. In addition, the oral examination will includes a powerpoint presentation on a topic of the students’ choice, the subject of the written essay. The methods and verification of the in-depth study, as well as their evaluation are detailed in the first lesson.

Contents
The course is divided into two parts. In the first part of the course the basic notions on the electronic structure of solids will be recalled (tight binding method - LCAO), to then discuss the fundamentals of spectroscopy (Fermi Golden Rule and selection rules). Hints are then made to vibrations in solids (phonons and dispersion relations) and the related experimental investigation techniques. This first part of the course concludes with a review of the main techniques of spectroscopic investigation of solids using synchrotron radiation. The second part will address issues related to the use of spectroscopy techniques for the investigation of the chemical and physico-chemical properties of advanced materials. The course also includes a detailed description of the main characterization techniques of the optical properties and of the optoelectronic processes, fundamental for the knowledge and characterization of the photovoltaic device (eg. UVVIS spectroscopy, Raman, time-resolved photoluminescence, electroluminescence, pump probe ultrafast optical spectroscopy).
