Learning objectives
1.KNOLEDGE AND UNDERSTANDING.
The main course objectives are:
I)
• to provide students the knowledge of the main technologies for
renewable sources conversion and storage systems, and their best performances.
• to show students some examples of systems to generate, transmit and store energy in the Smart-grids, with special attention to the way energy is produced and stored and to the related issues.
• to give students the knowledge to size and design photovoltaic systems with and without battery banks.
II)
The knowledge of the main technologies of electronic and optoelectronic devices shows how the technological choices affect the final device
performance, in particular:
• device scaling and integration and related issues;
• state-of-the-art MOSFETs, memories, interconnection lines which will
be analyzed from the point of view of materials, technologies and
processes;
• basic operating principles of devices beyond traditional planar CMOS,
as FINFET, strained Silicon , etc. ;
2. APPLYING KNOWLEDGE AND UNDERSTANDING. The student will learn
to use CAD tools for electronic design both at device and system level. In
particular, the student will be able to use the acquired knowledge and
abilities:
I) at system level
• to design and size photovoltaic and storage systems on the basis of
required performance and environmental restriction.
II) at device level
• to model and simulate the thermal and/or electrical and/or optical behavior of an electronic device;
• to analyze the impact of different factors as the geometry, doping, material choice etc. on the final performance of electronic devices;
3. SOFT-SKILLS USAGE. The laboratory activity, usually carried on in small
group, is also a mean to stimulate the student soft skills that is the ability to group working, to interact effectively with coworkers and teacher, to schedule the work and optimize the time required by the activity.
Prerequisites
Fundamentals of electronics.

Teaching methods
The course is organized in traditional classroom lessons based on the topics listed in the course program section.
The teacher will provide the students with excercises on the topics illustrated during the theoretical part of the course.
A CAD based laboratory activity directed towards the study and
optimization of solar cell and power electron devices, as well as to design and size photovoltaic systems, will be part of course program. Participation to the laboratory activity is mandatory.
Assessment methods and criteria
The exam is oral and will verify the knowledge and understanding of the topics presented during the course.
The exam consists of two questions on the topics presented during the classroom lectures and the laboratory activities. There are no tests during the course.
Other information
Slides about arguments treated during the course will be prepared by the teacher and made available to students. The download of slides will be allowed for registered students from http://elly.dii.unipr.it/.
