Design of a photovoltaic power plant with battery storage for a family house in area Ústrašice
Wiesner, Lukáš ; Jandová, Kristýna (referee) ; Vaněk, Jiří (advisor)
The master thesis covers the design of a photovoltaic solar power plant for a selected family house in Ústašice in Tábor’s region The theoretical part summarizes the photovoltaic phenomenon, production, and differences of various technologies of photovoltaic panels and different types of battery storages. The project also includes the legislative and subsidy conditions in the Czech Republic related to the PV topic. The practical part of the thesis starts with information about the layout of the family house with an analysis of household consumption data for the last five years. The analysis is followed by the selection of a suitable type of system for photovoltaic water heating. Using multi-criteria analysis, the most suitable solar controller and PV panels are then selected. The proposed system is updated with other necessary components. Finally, a simulation of the system is created in PV*SOL to determine the lighting conditions and to evaluate the economics side of the entire project.

Design of a photovoltaic power plant on an industrial building to reduce energy consumption
Pospíšil, Filip ; Vaněk, Jiří (referee) ; Jandová, Kristýna (advisor)
The master thesis addressed the issue of reducing energy demand. The aim was to design a photovoltaic power plant for an industrial building, which will reduce this energy consumption. During the work, several simulations of different proposed photovoltaic systems were created and compared with each other, and the most suitable design was selected based on the input aspects. The theoretical background of the thesis has been used, which is described in the first two chapters. The thesis is supplemented by the calculation of the energy performance of the building, the project documentation of the chosen design and the analysis of the possibilities of how the surplus energy produced by the photovoltaic power plant can be utilised. Subsequently, an evaluation and conclusion are made.

Design of Perovskite Photovoltaic Solar Cells and Research of their Stability
Strachala, Dávid ; Šály,, Vladimír (referee) ; Sedlaříková, Marie (referee) ; Vaněk, Jiří (advisor)
The work in the first part describe the design of a perovskite photovoltaic cell with planar inverse structure using photovoltaically active material CH3NH3PbI3 and CH3NH3PbI3-xClx. The theoretical description of perovskite materials is supplemented by knowledge of degradation mechanisms reducing the resulting stability of samples and also presents a comprehensive overview of the technology development. The following text brings an innovative process for the perovskite photovoltaic cells production, which has enabled manufacturing of reproducible samples with parameters comparable to the foreign workplaces. The second part of the research analyzes the influence of the external environment to the samples and based on experimental outputs explains possible degradation mechanisms of perovskite material. At the final part of the dissertation thesis is presented and characterized unique structure of planar inversion perovskite cells with a material composition increasing the resistance against external humidity.

Development and Innovation of Manufacturing Processes for Thin-Film Solar Cell Functional Layers
Kadlec, Michal ; Vanýsek, Petr (referee) ; Tauš, Peter (referee) ; Vaněk, Jiří (advisor)
The doctoral thesis deals with a group of thin-film photovoltaic cells based on pigment or perovskite absorption layers of light energy. The principal functionality of the cell is based on the capture of light by the pigment on a photosensitized semiconductor anode with subsequent regeneration of the pigment by the electrolyte. In our research we focused on the preparation and optimization of perovskite solar structures based on TiO2/CH3NH3PbI3. A total of six series of experimental solar cells with a perovskite structure were produced. The first two series were realized according to the chemical formula CH3NH3PbI3. In the other series, we applied the theory of added chlorine, resulting in the chemical formula CH3NH3PbI3Cl2. We defined the requirements for the creation of an active perovskite structure in the cell and determined its photovoltaic properties depending on the composition.

Shared energy economy
Hráček, Martin ; Maule, Petr (referee) ; Vaněk, Jiří (advisor)
The bachelor's thesis focuses on the use of a photovoltaic power plant in a block of flats, electric power distribution to individual consumers and the economic impact. The first part describes the basic principle of the photovoltaic power plant and a description of the individual parts used for the implementation. The second part is devoted to the operational legislation of the Czech Republic and the foreign operation examples. The third part already provides the specific implementation proposal example, the specific implementation budgets and the economic evaluation of the entire project.

Design of a photovoltaic power system with battery storage for household purposes in area of Brno-mesto
Vrana, Martin ; Vanýsek, Petr (referee) ; Vaněk, Jiří (advisor)
Táto bakalárska práca sa zameriava na rešerš technológií obsiahnutých v návrhu fotovoltického systému, ako sú solárne panely, nabíjateľné akumulátory, a systémy na premenu elektrickej energie. Následne sú tieto informácie využité na návrh hybridného a sieťového fotovoltického systému pre rodinný dom nachádzajúci sa v lokalite Brno-Mesto. Plán realizácie je nájsť cenovo výhodné riešenie s rozumným časom návratnosti, ktoré prevažne pokryje energetický odber domácnosti. Takisto sú náklady každého zo systémov znížene o dostupné štátne dotácie podľa parametrov každej inštalácie. Sieťový systém je lacnejší ako hybridný systém, pretože systém neobsahuje drahé batérie. Preto má nižšiu dobu návratnosti šiestich rokov, v porovnaní so siedmimi rokmi v prípade hybridného systému. Hybridný systém je výhodný, pretože umožňuje lokálne ukladanie energie a poskytuje záložné napájanie v prípade výpadku prúdu. Dodávateľ elektriny umožňuje uložiť prebytočnú energiu vyrobenú systémami do virtuálnej batérie, z ktorej je možné počas roka čerpať v čase nedostatočnej výroby energie. V kombinácii so súčasnými vysokými cenami energie majú oba systémy relatívne krátke obdobie finančného bodu zvratu v porovnaní so systémami v minulosti. Finálny výber typu inštalovaného systému je na klientovi.
