Learning and Teaching Methods
The lecture will be held in a compact form in the first half of the summer semester. Content of the lecture will be extended via tutorials in which worked examples will be presented and students will have the chance to discuss with their tutor.
Lecture: ex-cathedra teaching with blackboard and presentation
Tutorial: Discussion of weekly exrcises, additional explanations to the lectures

Description of exams and course work
There will be an oral exam of 40 minutes duration. Therein the achievement of the competencies given in section learning outcome is tested exemplarily at least to the given cognition level using comprehension questions and sample calculations.
For example an assignment in the exam might be:
- Explain the difference between first and second law efficiencies with the example of a heat pump.
- Compare Ts diagrams of an ideal Rankine cycle and a Carnot cycle and discuss how the individual processes of the Rankine cycle are realized in a vapor power plant.
- What determines the reversible cell voltage of a fuel cell and what are the main loss channels?
- Derive an equivalent circuit for a solarthermal converter and determine the thermal efficiency from the corresponding balance equations.
- Discuss with energy and exergy flow diagrams the energy conversion processes in a photovoltaic cell and explain the physics behind the loss mechanisms.
Participation in the exercise classes is strongly recommended since the exercises prepare for the problems of the exam and rehearse the specific competencies.
The exam may be repeated at the end of the semester.
