Course and Exercise “Physics of solar cells”

Lecturer: Prof. Dr.-Ing. Rolf Brendel, 2 + 2 Semester credit hours
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 “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 “Semiconductor measuring techniques for photovoltaics”

Lecturer: Dr. Karsten Bothe, Prof. Dr.-Ing. Rolf Brendel, 2 Semester credit hours
Faculty of Mathematics and Physics
Leibniz Universität Hannover

In this course the production process of a crystalline silicon solar cell is considered from the silicon block to the solar cell. The relevant analytical techniques for the evaluation of the individual processes are presented and explained. These are analytical techniques for material characterization (conductivity, charge carrier density, charge carrier lifetime, defects, crystal orientation) for process characterization (dopant profiles, texture, layer thickness and refraction index) and for characterization of solar cells (current-voltage characteristic, quantum efficiency, reflection, shunt analysis, photo-and electroluminescence imaging).


Course „Working principle and technology of solar cells“

Lecturer: Prof. Dr. Robby Peibst, 2 Semester credit hours
Faculty of Electrical Engineering and Computer Science (MBE)
Leibniz Universität Hannover

This lecture provides a well-founded understanding of the principle working mechanism of solar cells. According to their relevance for world-wide photovoltaics, the lecture is focused on crystalline Silicon solar cells. However, most of the aspects discussed are generally valid for all semiconductor materials. Moreover, the most important aspects, challenges and recent developments in Si solar cell fabrication technology are presented. The lecture closes with the discussion of fundamental limits for the energy conversion efficiency and of novel technological concepts beyond the evolutionary improvement of the current technology.


Course „Introduction to electronic measurement data acquisition and processing with LabView“

Lecturer: Dr. Carsten Schinke, Prof. Dr.-Ing. Rolf Brendel, 2 Semester credit hours
Faculty of Mathematics and Physics
Leibniz Universität Hannover


Advanced practical: „Analysis of solar cells“

Lecturer: Dr. Carsten Schinke, Prof. Dr.-Ing. Rolf Brendel, 2 Semester credit hours
Faculty of Mathematics and Physics
Leibniz Universität Hannover

This course provides practical experience with the help of experimental setups for example of the recording of current-voltage curves on solar cells, the operation of atomic force microscopes or scanning tunneling microscopes, electron microscopy and semi-conductor spectroscopy, magnetic resonance in solid bodies, crystal structure determination with X-rays and X-ray photoemission (XPS).


Course and Exercise „Solar energy systems I: Thermodynamic principles“

Lecturer: Prof. Dr.-Ing. Oliver Kastner, 3 Semester credit hours
Faculty of Mechanical Engineering
Leibniz Universität Hannover

This course provides the scientific-technical principles for the evaluation of thermal solar systems and their integration into energy supply structures. The focal point here are the thermodynamic and fluid-dynamic methods which are required for the representation and evaluation of solar thermal systems. This particularly concerns balances of thermo- and fluid dynamics, stationarity and non-stationarity, local and integral formulations, solar irradiation and its terrestrially usable fraction, momentum and energy transport in solar thermal systems, solar collectors, efficiency levels, modeling and calculations, heat pumps, heating networks and storage.


Course and Exercise „Solar energy systems II: Components and systems“

Lecturer: Prof. Dr.-Ing. Oliver Kastner, 3 Semester credit hours
Faculty of Mechanical Engineering
Leibniz Universität Hannover


Course „Introduction to renewable energy technology“

Lecturer: Dr. Roland Goslich, 2 Semester credit hours
Hochschule Weserbergland (HSW), Hamelin

The course outlines the possibilities for using solar energy. It begins with outline data on energy production, continues by way of the basic physics of solar radiation, then solar thermal heat production and finally describes the basics of electricity production with the help of silicon solar cells. The course is designed for students in the sixth semester of the dual “Energy technology” course.
