High Temperature Processes in Silicon Solar Cells Production
Frantík, Ondřej ; Hudec, Lubomír (referee) ; Banský,, Juraj (referee) ; Szendiuch, Ivan (advisor)
The thesis is focused on high temperature processes in crystalline solar cells production. Main topic is diffusion of traditional dopants phosphorus and boron. Diffusion processes for creating solar cells are different from classical diffusion in semiconductor industrial. It is reason why the thesis describes crated layers in detail. Knowledge of diffusion processes is used for creating bifacial solar cells and development of a new phosphorus emitter for conventional solar cells. Bifacial cells are a new type of cells. Developed new emitter increases efficiency and decreases cost of solar cells production. Another part the thesis is devoted to the prediction of diffusion processes. New models of phosphorus and boron diffusion for photovoltaic industrial are created in software SILVACO. Models correspond with real results.

Fixed-charge examination by surface energy measurement
Mojrová, Barbora ; Boušek, Jaroslav (referee) ; Hégr, Ondřej (advisor)
This work is deal with development of alternative method measuring fixed charge in thin dielectric layers by surface tension. Presence fixed charge takes effect so-called Back Surface Field (BFS), which helps to decrease surface recombination velocity on back side of solar cell. In work is described experimental measuring on dielectric layers Al2O3, AlN, SiNx, Y2O3 and PSG deposit on crystalline silicon wafers. Surface tension (it is the same like surface free energy) is analyzed from contact angle size using See System.
