Thin layer for electrochromic devices
Pelčák, Vít ; Macalík, Michal (referee) ; Sedlaříková, Marie (advisor)
This diploma thesis deals with creation of transparent conductive layers on glass substrate, which serve as underlay for electrochromic layers. Zinc acetate dissolved in methane and distilled water serves as basis of solution. We are searching for optimal amount of either Fluor or Boron in depositted solutions to achieve best transparency and layer conductivity.

Carbon materials for supercapacitors
Moncoľ, Maroš ; Macalík, Michal (referee) ; Dvořák, Petr (advisor)
This project deals with various carbon electrodes in order to achieve the maximal capacitance of supercapacitors. In a theoretical part of this work, is described physical substance of supercapacitors, energy storage principles and carbon based materials. In an experimental part, is described preparation of electrodes, results and evaluation of measurement.

Thin Film Electrodes for Electrochromic Devices
Macalík, Michal ; Kadlec, Jaromír (referee) ; Nováková,, Sabina (referee) ; Sedlaříková, Marie (advisor)
The work deals with the deposition of layers for electrochromic device with different methods. Transparent electrically conductive layer of SnO2 was deposited by pyrolytic decomposition of peroxostannate solution. Hydrogen peroxide in starting solution contributes to the oxidation process of growth layers and to increase the electrical conductivity. Active electrochromic layer of WO3 was electrolytic deposited from the peroxotungstic acid solution. Optimal deposition time and the optimal annealing temperature of deposited layers were found. Passive electrochromic layer of V2O5 was deposited using dip-coating method from peroxovanadate solution. A contribution of solution diluted with distilled water was investigated. Found results were used to construct complete electrochromic device with polymer gel electrolyte.

Electrodes materials for electrochromic devices based on V2O5
Janov, Pavel ; Macalík, Michal (referee) ; Sedlaříková, Marie (advisor)
The bachelor thesis deals with researching electrodes materials for electrochromic device based on V2O5. The wokr is dividet into two areas – teoretical and practical part. Teoretical part is aimed at elektrochromism, deposition thin layers manely V2O5. Consenquetial part is concentrated on glass substrate covered conducted film and was set their elektrochromic point. Then was found influence subsidy these layers with sodium and observed with sample without subsidy.

Thin layer WO3 for electrochromic devices
Jakubis, Ivan ; Macalík, Michal (referee) ; Sedlaříková, Marie (advisor)
This work deals with issues of electrochromism and coating method electrodeposition. Electrochromic thin-films of tungsten oxide (WO3) have been electrodeposited on glass substrates covered with transparent conductive thin-film SnO2:F (FTO). Elektrochromic characteristics of these substrates that were electrodeposited for different times have been studied. Than there have been studied the impact of various annealing temperatures on electrochromic characteristics. In this work also have been compared electrolytes LiClO4 and NaClO4.
