Reflex Treatment of Transparent Materials
Meluzín, Ondřej ; Tulka, Jaromír (referee) ; Molliková, Eva (advisor)
This thesis deals with the possibilities and methods of coating of transparent materials in order to improve their optical-reflective properties. It describes various methods that nowadays coatings can be applied on an industrial scale, while maintaining a constant thickness and properties across the applied coating. Further provides specific examples of how the application of different optical coatings can improve the desired properties of materials used for technical applications.

Lighting systems in off-grid applications
Lengyel, Ladislav ; Škoda, Jan (referee) ; Baxant, Petr (advisor)
Aim of the master's thesis is at first to explain appropriate light sources and lighting systems; secondly present suitable light sources selection for lighting a small space and design of an off-grid system. The last part consists of an overview about alternative energy transformations to light energy. The first of these three major themes focuses on the analysis of light sources suitable for use in applications with accumulation together with data on energy efficiency and the utilization efficiency associated with them, concentrating on their consumption and possible energy saving lighting within small applications. It ends with a description and calculations of electricity energy indicators for different types of rooms. The second and main part of the thesis is focusing on suitable light sources selection for off-grid systems and impacts on humans and the environment associated with it. An object representing a small application has been created in RELUX® software with suitable light sources installed in it. For this scene, appropriate parts of off-grid systems were selected, which could be used to power the proposed lighting. The last theme consists of a brief about alternative sources, most of which are still in development or existing only at a theoretical level. All of these alternative sources are having a possible application in the future.

The Business-Related and Logistical Challenges of Entering the African Solar Market. Illustrated on the Example of Solarity.
Widauer, Philipp ; Vinš, Marek (advisor) ; Kolář, Petr (referee)
The thesis evaluates the principal business-related and logistical opportunities and risks on the African solar market which is often associated to offer the last unexploited economic opportunities on this planet. For this purpose, the author examines three major African trade unions and reviews the strengths and weaknesses of each regional coalition. It becomes obvious that each respective trade bloc contains one dominant player, in this case Nigeria, Kenya and South Africa. The practical section starts with an analysis of the appropriate entry market for the Czech solar wholesaler Solarity. Subsequently, the author identifies South Africa as the best fitting market primarily because of good infrastructure, high purchasing power and a similar business culture. The author recommends that Solarity should apply an exporting entry mode due to its size and inexperience on the African market. Secondary research, first-hand experience and close cooperation with Solarity support the author in his final conclusions.
