Goal of the course is to

• understand the fundamental limits of solar energy conversion.
• know about the used materials and their electronic properties as well as the relevant technologies.
• be able to identify relevant characterization techniques for the analysis of specific material and device properties.

• understand the physical limits of the various characterization techniques.

The course will be held in English and addresses master and PhD students in physics, chemistry, and physical chemistry. Successful participation in the course and passing the oral exam is rewarded with a total of 10 ECTS credit points.
