Characteristics features of luminescence radiation solar cells
Malý, Martin ; Šimonová, Lucie (referee) ; Stojan, Radek (advisor)
This thesis deals with characteristic features of luminiscence radiation solar cells during electroluminiscence. Electroluminescence is the process in which a substance begins to radiate electromagnetic radiation (luminiscence radiation) due to passing electrical current. Various defects in the structure of the photovoltaic cell can cause polarization of that radiation. The aim of this thesis is to measure some polycrystalline solar cells by electroluminescence. Selected solar cell is measured by electroluminescence extended by polarizing filter and afterward collected data are processed in MATLAB.

Design of workplace for measuring photovoltaic modules in the controlled environment
Palla, Martin ; Vaněk, Jiří (referee) ; Veselý, Aleš (advisor)
BachelorQs thesis introduces basics of photovoltaic cells and modules. Diagnostic methods, which are used for detection of defects of photovoltaic cells and modules, are introduced. The aim of thesis is to propose measuring system, which will be able to detect particular defects and resolve their effect on total power. In the end of thesis there are 5 modules choosed, which have undergone measurement by electro-luminiscence method and FLASH method, which was realized at CTU Prague.

The diagnostics of fuel system in compression ignition engine Škoda Superb with injection CP4 Bosch Common Rail
ŠINDELÁŘ, Jan
This bachelor work is dealing with fuel system Bosch Common Rail in the car Škoda Superb.The main aim of this work is to describe and to explain working of this fuel system and consequently to evaluate its using in this car. The first part is about fuel system in compression ignition engines, its control and injection. In the next part injection and control of system Bosch Common Rail are explained and all the parts of this system are divided and described. In the next part legislation rules and demands of car repairing firms are written.In the last part there are described and divided diagnostic machines and diagnostics in this car is made. This work also includes evaluation of diagnostic results and suitability of using this fuel system in this car.
