Printed photoelectrochemical UV sensor
Vrbková, Kateřina ; Syrový, Tomáš (referee) ; Dzik, Petr (advisor)
This paper deals with the sensors, designed for ultraviolet light detection. There are many options in UV sensors construction. But in any case, there is a semiconducter used as a sensitive component. The most common photocatalyst is titanium dioxide. In electronic it is mainly used due to its suitable physical and chemical properties and good chemical stability. The aim of the work is preparation of gel electrolyte, which can close the electrical circuit between cathodic and anodic compartment and allows the passage of electrons. The hole first chapter is divoted to methods of UV sensors production, including electrochemical method on which is based our sensor.

Mechanical properties of gel polymer electrolytes
Bárta, Vladimír ; Vondrák, Jiří (referee) ; Sedlaříková, Marie (advisor)
This work deals with the measurement of electrical conductivity and mechanical properties of gel polymer electrolyte containing Lithium ion. Their preparation and performance depends on the concentration of nanoparticles Al2O3 contained therein. The theoretical part deals with the development of gel polymer electrolyte, their use and methods of measurement of electrical conductivity and mechanical properties. In the experimental part describes the preparation of gel electrolyte, the measurement of electrical conductivity, temperature dependence and the measurement of mechanical properties.

Materials for Supercapacitors
Dvořák, Petr ; Paidar,, Martin (referee) ; Trnková, Libuše (referee) ; Sedlaříková, Marie (advisor)
This dissertation deals with the electrode materials, liquid and gel electrolytes suitable for supercapacitors. In the field of electrode materials were investigated carbon materials based on carbon blacks, expanded and micronized graphite suitable for supercapacitors working on the principle electrochemical double layer. Another area which this thesis deals with are aprotic liquid electrolytes prepared from suitable types of salts and aprotic solvents. The last part is focused on the preparation and subsequent electrochemical characterization of gel polymer electrolytes in order to increase the ionic conductivity of these electrolytes.

Optimalization of gel electrolyte for printed UV sensor based on photoelectrochemical cell
Vrbková, Kateřina ; Gemeiner,, Pavol (referee) ; Dzik, Petr (advisor)
This paper deals with the construction of photoelectrochemical cell, used for detection of ultraviolet radiation as a UV sensor. Photoelectrochemical cell consists of three layers, layer of photoactive semiconductor titanium dioxide, carbon electrodes and poly(vinyl alcohol) polymer electrolyte. The sensor layer enables the detection of UV radiation with the subsequent generation of photocurrent. Material printing techniques, such as screenprinting, pad printing and inkjet printing were used to produce the cell. Gel electrolyte was characterized by optical microscopy and rheometry. Sensor functionality was verified by use of electroanalytical techniques.
