Organic solar cells based on lowmolecular materials
Omasta, Lukáš ; David, Jan (referee) ; Weiter, Martin (advisor)
This bachelor thesis is focused on characterization of new organic materials suitable for use in solar cells. In the theoretical part, there is research on organic solar cells together with description of the photovoltaic energy conversion. In this part, description of the structure and general properties of materials used to produce solar cells is given. The individual characterization methods are also described. The practical part includes the preparation of thin layers of organic materials and their optical characterization. Preparation of solar cells with classic structure is also included together with evaluation and comparison of their photoconductivity and efficiency.

Luminescence of organic materials for advanced applications
Dozbaba, Jaroslav ; David, Jan (referee) ; Vala, Martin (advisor)
The thesis deals with study of the radiation recombination of excited states in organic materials, induced by optical and electrical excitation. These processes are studied by optical spectroscopic methods and characterization of electroluminiscence. The theoretical part contains search and summary of basic knowledge necessary for interpretation of data focusing on the fluorescence of organic substances. The conversion processes of electric energy to an electromagnetic radiation in organic electroluminiscence diods were also discussed in the thesis. The practical part describes preparation of model diods, the study of their optical properties and characterization of their electroluminescence.

Diagnostic research of the family house
David, Jan ; Láník, Jaromír (referee) ; Schmid, Pavel (advisor)
This bachelor’s thesis deals with technical construction research of the family house which is located in 15 Horní Street in Brno. Technical construction research had to be made, due to the change of the owner of the house and to determine the status for possible reconstruction. Research includes description of the methodology of diagnostic work on building and evaluation of research with results and draft measures. The results consider the state of structure and status of its component parts.
