Programma dettagliato e risultati di apprendimento attesi

Objectives:

The course is mainly focused on the description of the physical principles of the photovoltaic and the thermoelectric energy conversion effects, and the description of the properties of materials of interest for such applications, with particular attention to new nanostructured materials and systems. Specific lectures will be focused on the principles and nanomaterials-related aspects of other direct energy conversion technologies.

Programme:

- Introduction to direct energy conversion technologies
- Properties of solar radiation
- Review of semiconductor physics and properties
- The photovoltaic effect; p-n junction under illumination, I-V characteristic of solar cells, definition of power conversion efficiency and quantum efficiency; limits for the efficiency
- Crystalline Si solar cells (1st generation): thin film solar cells (2nd generation)
- Excitonic solar cells, organic (bulk heterojunction) and hybrid solar cells, dye-sensitized (and related) solar cells
- New concepts for 3rd generation solar cells (tandem or multijunction cells, intermediate band cells, Multiple Exciton Generation, hot carrier cells, up- and down-conversion, concentration)
- Nanostructured materials for 3rd generation solar cells (e.g. QD-based solar cells)
- Phenomenology of thermoelectric effects (Seebeck, Peltier, Thomson); efficiency and figure of merit of thermoelectric systems (refrigeration and power generation)
- Introduction to irreversible thermodynamics; kinetic coefficients and Onsager theorem
- Microscopic description of charge and heat transport in solids: Boltzmann equation; derivation of thermoelectric coefficients for metals and semiconductors
- Conventional and advanced thermoelectric materials; the phonon glass-electron crystal concept, the substructure approach; Bi2Te3 and related compounds, skutterudites, chlatrates, complex oxides
- Nanostructured thermoelectric materials, examples (superlattices, nanowires, nanocrystalline or nanocomposite materials)
 
If possible, and if permitted by the schedule of lectures, at the end of the course specific lectures on other energy conversion technologies involving nanomaterials will be organized (e.g. fuel cells, solar water splitting, batteries).

Requested background:

A background in solid state physics is preferable. Selected topics of semiconductor physics and transport phenomena in solid state materials reviewed or discussed during the course can be found in most solid state physics texts. See bibliography for suggested books covering more than the programme of the course. Additional material or lecture notes will be made available by the lecturer.


Note Sulla Modalità di valutazione

The examination is an oral discussion about the course topics (typically one topic related to physics and materials for photovoltaics and one topic related to thermoelectricity and thermoelectric materials, chosen by the examiner).
