Teaching Methods

The course consists of theoretical lessons (60 h), classroom exercises (9h) and laboratory exercises (21h).


Verification of learning
The examination consists of an oral test at the end of the course or in alternative of 2 written tests already during the course and additionally the discussion of the protocols, regarding the laboratory exercises. The first written test regards optoelectronics and the second test regards photovoltaics. The final vote is calculated in equal parts using the 2 written tests during the course and the final discussion of the laboratory exercise documentation.
