Jedes Modul umfasst 3 ECTS. Sie wählen insgesamt 10 Module/30 ECTS in den folgenden Modulkategorien:
- 12-15 ECTS in Technisch-wissenschaftlichen Modulen (TSM)
TSM-Module vermitteln Ihnen profilspezifische Fachkompetenz und ergänzen die dezentralen Vertiefungsmodule. - 9-12 ECTS in Erweiterten theoretischen Grundlagen (FTP)
FTP-Module behandeln theoretische Grundlagen wie die höhere Mathematik, Physik, Informationstheorie, Chemie usw. Sie erweitern Ihre abstrakte, wissenschaftliche Tiefe und tragen dazu bei, den für die Innovation wichtigen Bogen zwischen Abstraktion und Anwendung spannen zu können. - 6-9 ECTS in Kontextmodulen (CM)
CM-Module vermitteln Ihnen Zusatzkompetenzen aus Bereichen wie Technologiemanagement, Betriebswirtschaft, Kommunikation, Projektmanagement, Patentrecht, Vertragsrecht usw.

This course focuses on the advanced understanding of the main components of Photovoltaic PV power generation systems.
The goal goes beyond the competence to design a PV System, like the installer business is used do, but also to understand how the components are working in detail, either for different PV module technologies as well as for different inverters power electronic topologies. Due to the fact, that in Switzerland some employees in the PV sector are not installing any PV system, but working for companies supplying component of turn-key PV module production lines for the world market, the main concepts of processes and different concepts of PV module production lines are discussed in the course also. Analysis of the economic parameter of state of art PV systems, together with environmental key factors like energy pay back times will complete this PV course. Today the numbers of PV systems including a battery system to use PV electricity at night is growing in Switzerland. The power electronic concepts and energy flows in these grid connected PV storage systems are discussed.

Lernziele
The students will be able not only to know the different type of Photovoltaic components on the market, but they should be able to work for companies to be able to improve these products on the technology level. Thus in the course exercises this technology knowledge will be trained focused on the applied research needs in the industry in power electronica as well as PV module production technologies, battery storage and PV plant design.
