Materials for Energy Conversion and Conservation
The aim of this discipline is to nurture the students'' knowledge on the:
- introduction to global energy challenges
- systems for solar to electrical energy comversion: working principle of a solar cell, production processes, materials that can be used, vantages and disadvantages at economical and environmental level;
- systems for the conversion of solar to thermal energy: importance of the protection/materials radiation absorbers, materials employed and in development;
- systems for conversion of thermal to electrical energy through the thermoelectric effect (Peltier elements): working principle, materials used, production processes;
- systems for convertion of mechanical to electrical energy: piezoelectrics and nano-generators;
- systems for energy storage: batteries and supercapacitors; electrochemistry and fuel cells.

The discipline has two hours of theoretical lessons a week and 3 hours of theoretical-practical lessons and laboratories.
A PowerPoint presentation is used for theoretical classes being the matter exposed in a class room.
The resolution of exercices is done during the theoretical-practical lessons in class room about the matter given during the theoretical classes.
Laboratorial classes are related to the experiences demonstration of the concepts already given both in theoretical and problem sessions
- Average of 2 Tests of continuous evaluation (no minimum grade required to do exam) or Exam grade (60%);
- Report about the photovoltaic characterization work (25% of grade)
- Report about the PV system dimensioning plus batteries work (15% of grade)
Minimum grade to pass: 9.5
The practical group projects will be explained to the students and the experimental data will be provided for the students to analyze.
