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.

Japanese political parties and democracy in the 1920s
Kafka, Martin ; Labus, David (advisor) ; Sýkora, Jan (referee)
V této práci jsem se zabýval vývojem, kterým politické strany v Japonsku prošly, cíle které si stanovily a za jakých podmínek působily. Konkrétně změny jejich postavení, významu a chování v rámci systému vytvořeném Ústavou Meidži. Společně s tím jsem se pokusil postihnout demokratizační změny, kterými japonská společnost ve svém moderním předválečném období prošla.

Influence of Foreign Policy on Relationship of the Japanese Political Parties and Military in the Interwar Period
Kafka, Martin ; Labus, David (advisor) ; Sýkora, Jan (referee)
In this thesis I primarily studied the influence of foreign policy on the development of relations between Japanese political parties and the military in the interwar period. I studied the way in which political parties and military affected each other and which factors influenced the distribution of power on Japanese political scene. Furthermore I tried to show how these relations contributed to the rise of power of political parties and to their subsequent downfall, and how they affected the militarization of Japanese state and it's consequent course towards World War II. Therefore I focused the thesis on 1921 - 1936 period, in which the key events that formed the shape of Japanese state, at least until the end of World War II, took place.
