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.

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.
