Silicon solar cells: methods for experimental study and evaluation of material parameters in advanced structures
Holovský, Jakub ; Vaněček, Milan (advisor) ; Sládek, Petr (referee) ; Hlídek, Pavel (referee)
This work concerns with today's challenges of photoelectrical characterization methods in the research and development of thin film silicon solar cells. Relevant results are obtained only when photocurrent spectroscopy and measurement of current-voltage characteristics, are applied on the real structures that can however be multi-layered, multi-junction devices with nanostructured interfaces. Analytical and numerical optical models comprising light scattering are used for analysis of light absorption and for evaluation of optical absorption coefficient of silicon layers in sub-gap region. The slope of absorption edge and residual absorption in mid-gap indicate material disorder and defect density. Based on the investigation of electrical interaction between sub-cells in the dual-junction solar cell we developed new methods of evaluation of photocurrent spectra and current-voltage characteristics individually for each sub-cell with no need to contact them directly. Usability of Fourier Transform Photocurrent Spectroscopy as a robust method for photocurrent spectroscopy of amorphous silicon is thoroughly analyzed here. The issues of frequency dependence are addressed in detail and comparison with photothermal deflection spectroscopy is made.

Erotica in a puppet animated film
Žák, Vojtěch ; DĚCKÁ, Eliška (advisor) ; Vaněček, Matěj (referee)
Eroticism and pornography in animated puppet film is a niche genre. Nevertheless, it deserves attention for its unique means of expression. The subject matter of this thesis is a reflection on the relationship between corporeality and the puppet in film. It also includes selected auteur independent films and their analysis, in which sexual behavior is the prevalent topic or which contain explicit erotic scenes.
The puppet functions as a representation of human body; specifically, within the context of this thesis, of the body in erotic situations. The body of the puppet becomes a representation of our own body. With the emergence of new technologies, we can become a representation of the puppet, which in turn becomes a puppeteer, an animator. The principle of identification with the main protagonist is essential for interpretation of the role and function of the puppet in film. One of the key instruments of interpretation of the role of the puppet in film and understanding its function in film. The chosen theme is accompanied by definitions of key terms and a brief overview of legislation concerning pornographic animated film.
