MSE Master of Science in Engineering

The Swiss engineering master's degree


Each module contains 3 ECTS. You choose a total of 10 modules/30 ECTS in the following module categories: 

  • 12-15 ECTS in technical scientific modules (TSM)
    TSM modules teach profile-specific specialist skills and supplement the decentralised specialisation modules.
  • 9-12 ECTS in fundamental theoretical principles modules (FTP)
    FTP modules deal with theoretical fundamentals such as higher mathematics, physics, information theory, chemistry, etc. They will teach more detailed, abstract scientific knowledge and help you to bridge the gap between abstraction and application that is so important for innovation.
  • 6-9 ECTS in context modules (CM)
    CM modules will impart additional skills in areas such as technology management, business administration, communication, project management, patent law, contract law, etc.

Photovoltaic (TSM_Photo)

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.

Prerequisites

Basics in Physics, Electronics

Learning Objectives

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.
