Pavlovič, Dean ; Toušek, Jiří (advisor) ; Křivka, Ivo (referee)
Title: Properties of solar cells based on polymer-silicon junction Author: Dean Pavlovič Department / Institute: Department of Macromolecular Physics Supervisor of the bachelor thesis: doc. RNDr. Jiří Toušek, CSc, Department of Macromolecular physics Abstract: The aim of this work is to study unconventional materials, namely conjugated polymers, as to be used for photovoltaic purposes. Among these polymers are polyaniline, derivative of polyphenylene vinylene and two derivatives of polythiophene. Four different methods are used to study some of the physical quantities of the samples, that should affect overall efficiency of solar power conversion. Firstly, I-V characteristics yields fill factor and indicates mechanism of charge transport. Method based on surface photovoltage (SPV) estimates diffusion length of the charge carriers - excitons. Impedance spectroscopy and particular method abbreviated CELIV both measure charge carrier mobility. Outcome of this work are the values of these quantities for some of the samples. Keywords: organic semiconductors, solar cells, mobility, diffusion length, current-voltage characteristic

Tax aspects of selected corporate
Kotlaba, Drahomír ; Vančurová, Alena (advisor) ; Finardi, Savina (referee)
The subject of my bachelor thesis is tax duties of a company operating a photovoltaic power plant in the Czech Republic. Firstly, relevant taxes which the company is obliged to pay are identified and the basic parameters of these taxes are also described. Furthermore, tax risks resulting from changes of tax legislation in 2010 in respect of corporate tax (cancelation of tax holiday, specific rules for tax depreciation) and an introduction of a solar levy are also specified.

Současnost a budoucnost fotovoltaiky v České Republice z pohledu velké energetické společnost
Burianová, Eva ; Jaklová, Martina L. (advisor) ; Kubín, Petr (referee)
Goal of this thesis is to analyse sequence of events that led to current situation on the solar market in Czech Republic. Based on this analysis, current situation and scenarios for the near future from the point of view of large power utility company are described. For this aim, analysis of macro-environment is employed and focuses in detail on legislative and technological factors. Definition of possible scenarios starts with the description of current situation of saturated market. Solar power plants are then presented as reasonable equity investment from the point of view of large power utility company. Assumptions and entry data are described and the investment is evaluated using the net present value evaluation tool. For chosen entry parameters, sensitivity analysis is performed. This thesis then defines the situation when electricity produced from solar irradiation becomes competitive with other conventional sources.

Štrynclová, Monika ; Svobodová, Ivana (advisor) ; Čapek, Pavel (referee)
The graduation theses is concerned with elaboration of business plan whose theme is building of solar power station in locality of Velké Hamry. The aim of graduation theses is evaluation of building and operation of solar power station through the medium of methods which make for assessments of investment as well as entire business plan processing which should be used in application for granting of credit and in application for financial support of Operational program of Enterpreneurship and Innovation.
