The power of solar radiation falling on a photovoltaic module
Kaliyev, Alexey ; Jandová, Kristýna (referee) ; Křivík, Petr (advisor)
The work is focused on the problem of the solar radiation power impacting on a photovoltaic module. In the theoretical part, the possibilities of using solar energy in renewable energy sources, especially in photovoltaic panels and solar collectors, were discussed and presented. Then the materials on the use of solar energy in these sources were reviewed. In addition, the three main components of incident solar radiation on a photovoltaic module or solar collector were described. Finally, the method for calculating the position of the sun across the sky was discussed and presented, as well as the method for calculating the various components of incident solar radiation on a photovoltaic module.

V-I characteristic of solar cells
Kaderka, Tomasz ; Křivík, Petr (referee) ; Vaněk, Jiří (advisor)
The theoretical part is to outline the possibilities of solar energy conversion, learn about the issues solar cells and describe the history of photovoltaics and photovoltaic energy conversion. Then describe principle of the measurement VA characteristics of photovoltaic cells. This issue is not as easy as it seems at first sight, because the solar cell isn’t a linear component, which is very easy to measure. Analysis of VA characteristic of photovoltaic cells affects parameters such as: light intensity, temperature, serial and parallel resistance, the slope of the light source, and more. The practical part deals with creating a workplace for automatic measurement of VA characteristics of photovoltaic cells in the LabVIEW. Challenge is to create a functional program, which automatically measures the VA characteristics not only in the lighted cells, but also in the shaded cell (diode mode). The program calculates the power and important parameters, such as short-circuit current, open circuit voltage, maximum power, current and voltage at maximum power article. The program allows you to export the measured values to a text file. In the last chapter of this work is made control measurements of three samples of monocrystal photovoltaic cell by the measuring workplace. The measurement is compared with the reference device Solar Cell Tester.

Photoluminescence diagnostic method with transmission illumination
Kafka, Martin ; Veselý, Aleš (referee) ; Vaněk, Jiří (advisor)
The aim of this diploma thesis is an innovation of photoluminescence measure research workplace for measurement of cells structure defects by method of transmissive illumination while employing the current methods of measurement of defect in the solar cells structure. The first part deals with explanation of historical development of solar energy, of how we can reach production of electric power with contribution of solar radiation and defines usability of solar cells in practice. The thesis further analyses a practical application of measurement via laboratory diagnostic methods used by Department of Electrotechnology Brno University of Technology. The second part is focused on mechanical design of experimental photoluminescence measure workspace used for quick diagnostic defects employing the rear arousing source for detection of defects with assistance of transmissive system of illumination. Finally, with co-operation of SOLARTEC s.r.o. three types of solar cells are measured by this new method and compared with results of measurement via diagnostic methods of LBIV (Light Beam Induced Current), LBIC (Light Beam Induced Voltage), Electroluminescence, Photoluminescence, and detection defects by radiation of Microplasma.
