Content, Learning Outcome and Preconditions
Photochemical Energy Conversion and Artificial Photosynthesis
For the transition to a renewable energy based energy supply, the greatest challenge is the energy storage to compensate for the daily and yearly variability of wind and solar energy. Owing to their high energy density and temporally unlimited storage capacity, fuels, such as hydrogen, methane or liquid hydrocarbons, present the ideal storage medium.
In the lecture we will discuss in-depth state of the art routes to store solar energy directly in form of chemical energy. These routes involve absorption of solar light (mainly by a semiconductor), and accumulation of the minority charge carriers at the semiconductor surface followed by charge transfer of an electron or hole to a chemical species, such as water or carbon dioxide. Artificial pathways to solar fuels will be compared to natural photosynthesis. The lecture will provide foundations of the various areas being necessary to understand the production of fuels from sunlight: semiconductor physics, semiconductor surfaces, the solid-liquid interface, electron transfer theories, experimental techniques, state of the art of water splitting and carbon dioxide reduction.
After participation in the Module the student is familiar with the prospects of photochemical energy conversion for future energy storage technologies. In particular she/he is able
1. to explain the physical foundations needed for photochemical energy conversion
2. to determine the efficiency of individual energy transfer processes with physical concepts
3. to assess the rank of solar fuels in a future renewable energy scenario
4. to estimate the applicability of different production routes of solar fuels
5. to compare photochemical energy conversion to alternative concepts

Description of exams and course work
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.
The exam may be repeated at the end of the semester.
