Course and exercises “Physics of solar cells”
Lecturers: Prof. Dr.-Ing. Rolf Brendel, Dr. Carsten Schinke

2 Semester credit hours lecture and 2 SCH exercise
Faculty of Mathematics and Physics, Leibniz Universität Hannover

This course deals with the basics of semi-conductor physics and all physical processes which are important to the function of a solar cell. At the same time, in particular, the optical characteristics of the semi-conductor, the trapping of light in the solar cell, the transport of electrons and holes as well as the recombination of charge carriers are considered. The course gives an introduction into the production and experimental characterization of solar cells. The physical limits of the efficiency levels of solar cells are calculated. The course is aimed at students of physics and engineering science from the fifth semester onwards.

Course “Characterization of Semiconductors and Solar
cells”

Lecturer: Prof. Dr. Jan Schmidt

2 Semester credit hours
Faculty of Mathematics and Physics, Leibniz Universität Hannover.

The first part of this lecture deals with the fundamentals of semiconductor physics in connection with characterization
methods for semiconductor materials. One focus is on methods for characterizing defects in semiconductors and their effect on the electrical properties of the semiconductor. In the second part of the lecture, methods for the characterization
of solar cells are presented, including integral methods
such as spectral response as well as spatially resolved methods such as camera-based photoluminescence.

Course “Fundamentals of semiconductor physics”
Lecturer: Prof. Dr. Jan Schmidt

2 Semester credit hours
Faculty of Mathematics and Physics, Leibniz Universität Hannover

This course deals with the electronical and optical properties of semiconductors and their application in devices. The course includes in particular the following topics: band theory, intrinsic and extrinsic conduction, defects in semiconductors, recombination processes, carrier transport, pn-junctions, heterojunctions, metal-semiconductor junctions and semiconductor devices (diodes, transistors, photodiodes).

Course “Present physics – Physics of energy conversion”
Lecturer: Prof. Dr. Rolf Brendel

2 Semester credit hours
Faculty of Mathematics and Physics, Leibniz Universität Hannover

In this course students learn and deepen presentation techniques and literature research based on the issue of energy conversion from renewable and conventional sources. The focus lies on the physical fundamentals and processes for providing electrical power using renewable and conventional techniques. In the field of renewable energies, this includes wind, water and solar energy. In addition, we look at the structure, components and functionality of thermal power plants from a physical point of view. Different sources of thermal energy, such as combustion of fossil raw materials
and renewable heat sources, will also be dealt with.

Course “Introduction to Electronic Measurement Data Acquisition and Processing with LabView”
Lecturer: Dr. Carsten Schinke

4 Semester credit hours
Faculty of Mathematics and Physics, Leibniz Universität Hannover

The course gives an introduction to the principles of electronic measurement data acquisition and processing with the LabView graphical programming environment often used in research and industry. The focus is on the compilation of measurement data with data acquisition cards as part of small experiments carried out on the PC and the subsequent further processing of this data with the PC. In addition, the physical principles of the functioning of the sensors used and the principles of the systematic consideration of measurement uncertainties are also considered.

Course and exercises “Operating principle and technology of solar cells”
Lecturers: Prof. Dr. Robby Peibst, Dr.-Ing. Jan Krügener

4 Semester credit hours
Faculty of Electrical Engineering and Computer
Science (MBE), Leibniz Universität Hannover

Participants receive detailed basic knowledge of the functionality of silicon solar cells and their manufacturing technology, an understanding of the efficiency limits and loss phenomena actually occurring in solar cells as well as basic knowledge of component and process characterization.

Course “Bipolar devices”
Lecturer: Prof. Dr.-Ing. Tobias Wietler

2 Semester credit hours
Faculty of Electrical Engineering and Computer Science, Leibniz Universität Hannover

This lecture course looks into basic semiconductor physics including charge carriers in semiconducting materials, current transport mechanisms and generation and recombination processes. This forms the base for the discussion the static and dynamic characteristics of pn-junctions, metal-semiconductor junctions and semiconductor heterojunctions including a brief introduction to optoelectronic devices. In a special workshop, students give short presentations on different types of diodes and their application. Bipolar junction transistors from basic principles to dynamics and hetero bipolar transistors are also covered.
