Teaching methods

The course consists of

1) lectures in classroom;

2) training on design of a phovoltaic plant, storage system and fuel cell by using commercial softwares;

3) laboratory demonstrations on superconductors, batteries and photovoltaic cells.

Assessment methods

The exam for attending students can be divided into two partial tests on half the program: an intermediate test, approximately halfway through the course, and a final test, immediately after the end of the course. The mid-term exam is written while part of the final exam could be oral.

Both tests, lasting a maximum of two hours each, consist of 10 open-ended questions and / or exercises on the topics relating to the parts of the program covered by the test itself. Eight of these questions require short and targeted answers while the remaining two require a broader and more articulate answer, possibly even oral if required by the test.

Each test is assigned a maximum score of 32; sufficiency is achieved with a score of 18. An insufficiency or absence from the first partial test precludes the possibility of taking the second. The final mark, out of thirty, is obtained from the arithmetic average of the marks of the two tests rounded to the nearest integer. Honors can be awarded if the final score is ≥ 31. Once the final grade is known, the student must decide whether to accept or reject the grade before the deadline communicated by the teacher.

The refusal of the grade, insufficiency, or absence in one or both partial tests involves the repetition of the exam in a single session on the whole program.

All sessions following the final partial exam will take place over the entire program in a single session in the same way as the partial tests described above.

Passing the exam will be guaranteed to students who demonstrate mastery and operational skills in relation to the key concepts illustrated in the teaching, and in particular to photovoltaic, superconducting technologies and related to electrochemical storage systems.

A higher score will be awarded to students who demonstrate that they understand and are able to use all the teaching contents, illustrating them with language skills, solving even complex problems and showing good operational skills.

Failure to pass the exam may be due to insufficient knowledge of key concepts, in particular relating to traditional and innovative storage systems, superconductivity phenomena, and photovoltaic systems, as well as the lack of mastery of technical language.

If the final grade is less than 18/30 the student will be rejected and will not be able to take a new test before 15 days.

The student has the right to reject a positive grade assigned by the teacher a maximum of two times.
