Inovation of measurement equipment used for analyzing of photovoltaick cells
Otépka, Jakub ; Bača, Petr (referee) ; Vaněk, Jiří (advisor)
This bachelor thesis deals with the design of a tachometer which is used to measure and display of mechanical aperture speed of a measuring equipment for the defect analysis of solar cells using the photoluminescence method. This work is divided into three parts. The first section describes the principle of solar cells, the principle of luminescence radiation and its types. Next the defects of solar cells are analyzed. The second part discusses the theory of tachometers, the principles and methods of loading pulses. The third part is then analyzed the design and construction of the selected type tachometer.

Influence of magnetic field on photovoltaic solar cell
Kadlec, Michal ; Šubarda, Jiří (referee) ; Šimonová, Lucie (advisor)
This thesis describes the issue of PN junction of photovoltaic cells, photovoltaic effect physics, basic materials used in photovoltaic and their properties, important for the area of photovoltaic. It deals with the problems of magnetism focused on electromagnetic fields. Experimental facility for measuring the influence of magnetic field on the solar cells through the Helmholtz coils was constructed. This work also dealing with the influence of magnetic radiation on photovoltaic cells and the influence of electromagnetic waves on the volt-ampere characteristics of the photovoltaic cell.

Photovoltaic system with sun-tracker
Riabov, Mikhail ; Křivík, Petr (referee) ; Vaněk, Jiří (advisor)
The aim of the bachelor thesis " Model of photovoltaic system with solar tracker“ is to apprise with principles of operation of solar systems. We will focus on the tracking system, which is turning itself depending on the position of the sun. In the theoretical part we will describe the principle of operation of photovoltaic cells and solar systems. In the practical part of the work we will compare the parameters of the static and dynamic solar system and make decision, which of these systems is more profitable for use.
