Study of magnetic structures in the solar corona
 ŠEBELÍK, Václav
The thesis presents a comparison of data obtained from the solar radio spectrograph RT5 in Ondřejov and data from the space probe SDO. In the theoretical part of the thesis the solar corona and the current state of knowledge are briefly described. The practical part is devoted to the processing of obtained data using developed programs. From all of structures found in the spectrograms, zebra structures have been selected for more detailed study.

Diagnostics of passivation layers for crystalline silicon solar cellls.
 Sládek, Karel ; Hégr, Ondřej (referee) ; Boušek, Jaroslav (advisor)
The work deals with a comparison of existing and perspective types of passivation and anti-reflective coating for silicon solar cells. The theoretical part describes the appropriate methodology for the characterization of these layers and focuses on the passivation layers based on Al2O3. The practical part describes design and verification operations of the equipment for measuring of the amount of fixed charge in the passivation layers using corona discharge. It also describes the implementation of equipment and the results of indicative tests for positive and negative polarity of high voltage. The final part discusses the possibility of equipment improving.
