Educational objectives
The course aims to provide students with the basic knowledge to be able to independently deal with the issues surrounding the current energy problem, with particular reference to chemical issues.

In particular, the students who attended the course:
- They know the physical and chemical principles related to production, conversion and storage of energy;
- They know the physical and chemical principles connected with the conversion of solar energy, the mode of operation of solar photovoltaic cells and electrochemical devices for the accumulation of electricity;
- They know the most suitable techniques, processes and materials for the optimization of devices for converting and storing energy.
Prerequisites
In order to be able to exhaustively understand the contents of the Course, it is necessary that the student has acquired the fundamental concepts of phtochemistry, electrochemistry and inorganic chemistry. Moreover, the expertise acquired through the Chemistry of the Atmosphere and the Chemistry of the Environmental Courses can be very helpful towards a full understanding of the Course's contents.
These prerequites are considered valid both for attending and not attending students.
Teaching methods
The course is organized as follows:
- lectures on the subjects of the course.

Learning verification modality
The exam includes an oral test lasting a total of approximately one hour. The oral test consists of two parts. In the first, the student presents a specific topic of the course, which he has explored independently in specialized scientific journals, possibly making use of the aid of slides. The treatment lasts approximately 10-15 minutes. This is followed by general questions on the topics covered in class. The discussion lasts approximately 30-45 minutes, and is aimed at ascertaining the level of knowledge and understanding achieved by the student on the theoretical and methodological contents indicated in the program (energy problem, energy storage, exploitation of solar energy,... ). The oral test will allow to verify the student's communication skills with language skills and independent organization of the presentation on the same topics with theoretical content. The test as a whole allows to ascertain both the capacity for knowledge and understanding, and the ability to apply the skills acquired, as well as the ability to exhibit, and the ability to learn and develop solutions independently of judgement.
