Responsible coordinator of the module PH2089 is Martin Stutzmann.
Content, Learning Outcome and Preconditions
The electronic, non-classical forms of renewable energy are contents of this module. Especially the energy conversionby photovoltaic processes as well as the analog biophysical phenomena during photosynthesis are handled. For photovoltaic processes discussed in particular all relevant generations- recombination phenomena in semiconductors are discussed, corresponding rate equations are analyzed and different types of solar cells are discussed. In a direct comparison with the photovoltaic, the fundamental biophysical and molecular processes of photosynthesis are presented and the use of biomass for energy production is discussed. Finally, the thermoelectric energy conversion as a field of research will be discussed. The physical basis of the seebeck effect, as well as the concrete realization of thermoelectric converters are also content of the lecture as the discussion of maximum efficiency and its improvement through the targeted use of nanotechnological approaches to increase the thermoelectric "figure of merit".
After successful participation in this module the students are albe to:
- describe the functional principles of photovoltaic and thermoelectric converters and their current-voltage characteristics.
- estimate the effect of loss mechanisms on the efficiency of such converters
- understand current optimization strategies to improve efficiencies and to reduce manufacturing costs and to estimate their potential.
- describe in comparison to these technological approaches the bio-molecular basis of photosynthesis and to classify the fact-based "biofuel" procedures in terms of their energy potential and its efficiency of the system.
Keine Vorkenntnisse nötig, die über die Zulassungsvoraussetzungen zum Masterstudium hinausgehen.

Description of exams and course work
|Exam type||duration||exam elements||repetition|
|mündlich||25 Minuten||following semester|
In an oral exam the learning outcome is tested using comprehension questions and sample problems.
In accordance with §12 (8) APSO the exam can be done as a written test. In this case the time duration is 60 minutes.
Remarks on associated module exams
If you vistited the courses of the associated module PH2088: Erneuerbare Energien 1 / Renewable Energies 1 during the previous semester but did not take the exam you can take both exams together. In this case you need to register for both exams in the second semester.
