asked questions

Are there any extra costs for the on-campus events?

No, not except for your own travel, accommodation, and personal costs. During the Campus Phase week, students come to Freiburg to meet instructors and fellow students and to get a hands-on experience at our facilities.

Two times during the program, participation is mandatory since you will be attending the SEE Lab Workshops exclusive to the SEE students. So, you just need to consider the expenses for travel, accommodation and personal costs.

Are there scholarships or financial support?

Unfortunately, at the moment, we do not offer any scholarships. So if you need extra help to finance your studies, we encourage you to begin your search for scholarships as early as possible. The international office of the university in your homeland, as well as the German embassy or consulate(s), may have information on scholarships for students who are specifically from your country or in your field of study.

Applicants can check the following links for third party scholarship opportunities:


The DAAD is an important German institution created for academic exchange. They provide a lot of information on their website about everything related to studying in Germany. They also have a database about scholarships; you can find information on various kinds of DAAD funding for international students, graduates, and postdocs, as well as on funding offered by other selected organizations here. They also host www.study-in.de, which is a website for international students in Germany.

M.Sc. fees per semester


The cost of each Certificate Program is 2500 € per semester. All certificates last one semester, except for the Solar Thermal Energy Technology which lasts two semesters; it's fees are 2,500 € in total, too.

What do I need to prove my English proficiency?

Due to the admission regulations, students may only be admitted if they have the English language certificate of at least level B2 according to the Common European Framework of Reference for Languages. English certificates must be handed in as officially notarized copies. Online versions - like, for example, the TOEFL “Test taker report” will not be accepted. Please carefully read the official requirements of the University for English language certificates here.


- Students from a country with English as an official language;

- Students holding a German or Luxembourgish “Abitur” with at least 7 Years of English;

- Students holding a previous degree (BSc) which was taught entirely in English (must be mentioned in the official transcript).

What does an official certification look like?

An official certification can be provided by any public body or government agency with an official seal or stamp (Dienstsiegel). Examples are registration offices (Bürgerbüros) or the local registration offices of the State Residents’ Registration Office (Einwohnermeldeamt), as well as embassies, consulates and sworn translators if foreign academic records are to be certified. German notaries are also authorized to perform certifications. The institution (school, higher education institution) that originally issued the record in question can also certify a copy of that record.

Certifications issued by attorneys, certified auditors, associations, health insurance companies, and DAAD (German Academic Exchange Service) or from AStA (Allgemeiner Studierenden Ausschuss) are not recognized.

Every official certification must include at least:

1. Certification notice (this is a notice stating that the copy is as per the original);

2. Signature of the party certifying the document;

3. Official seal or stamp. (An official seal or stamp generally includes an emblem. A simple inked text stamp is not sufficient).

If the copy consists of several pages, proof must be provided showing that each page comes from the same document. It is sufficient if only one page bears the certification notice and signature if all pages are stacked up, stapled together, and stamped or sealed in such a way that a part of the official seal or stamp appears on each page (see below at the upper left-hand corner of the sample).

A sample certification
What if I do not have an engineering background?

For M.Sc. in SEE, the knowledge of an engineering bachelor’s graduate is assumed and required in most lectures. Our experience over the previous years showed that it is better to have this knowledge for students, so that they don't feel overwhelmed with additionally having to learn the fundamental engineering topics.

For students without a strong engineering background, we recommend checking out the certificate programs, especially: 'Crystalline Silicon Photovoltaics' and 'Solar Thermal Energy Technology'. These programs still have a bit of Physics, Mathematics and Engineering content, but could be handled by students without deep knowledge in those areas. The description of these programs can be found here.

What is the language of this program? Do I need to know German?

The courses are taught only in English. Participants may choose to write their master’s thesis in German or French after the University committee’s approval. Please carefully read the official requirements of the University for the English language certificate here.

When do I obtain my Uni-Account?

Once the Student Service Center finalizes your enrolment, you will receive a system-generated email from the University IT department (RZ= Rechenzentrum) with your personal Uni-Account and a single-use password with a link to „myAccount“.

Please change your password on this platform and inform our IT support Daniel Sassiat (daniel.sassiat@rz.uni-freiburg.de) about this. He will then modify your Uni-Account as the last step. Afterwards, the account is fully usable (including VPN).
