Sionová, Marcela ; Navrátil, Jiří (referee) ; Weiter, Martin (advisor)
This bachelor thesis concentrates on the properties characterization of new organic materials for solar cells. In the theoretical part, there is a solar cells themed literature search and a description of the fotovoltaic energy conversion. The practical part includes the preparation of solar cells with classic and invert structure and comparsion their efficiency on transparent electrodes from a different producers.

Charge carrier transport in organic disordered materials
Češka, Matěj ; Navrátil, Jiří (referee) ; Weiter, Martin (advisor)
This bachelor´s thesis deals with organic materials for use in photovoltaic energy conversion. A theoretical part of this thesis contains brief introduction to organic photovoltaics. Thin organic films were prepared and were characterized by optical methods and by current voltage characteristics. It was found that the light illumination can improve conductivity of prepared thin layers.
